+## Introduction: The Challenge of Secrets Management
+
+In modern cloud-native environments, managing secrets is a critical challenge. Developers need to:
+- Store and retrieve database passwords
+- Generate SSL/TLS certificates
+- Rotate API keys regularly
+- Manage access policies across multiple services
+
+Traditional approaches involve:
+- Manual secret management (error-prone and insecure)
+- Complex CLI commands (steep learning curve)
+- Custom scripts and automation (maintenance burden)
+
+What if you could simply ask an AI assistant: "Store the production database password in Vault" or "Issue a certificate for api.example.com" and have it done automatically?
+
+This blog post demonstrates how to build exactly that: an AI-powered secrets management system using HashiCorp Vault, the Model Context Protocol (MCP), and kagent.
+
+## What We Built
+
+We created a complete integration that allows AI assistants to manage HashiCorp Vault through natural language. The system includes:
+
+**14 MCP Tools across 3 categories:**
+
+### Mount Management
+- `create_mount` - Set up new secrets engines (KV, PKI, Transit, etc.)
+- `list_mounts` - Discover configured secret storage locations
+- `delete_mount` - Clean up unused mounts
+
+### Key-Value Secret Operations
+- `read_secret` - Retrieve credentials and configuration
+- `write_secret` - Store passwords, API keys, and secrets
+- `list_secrets` - Browse available secrets
+- `delete_secret` - Remove outdated credentials
+
+### PKI Certificate Management
+- `enable_pki` - Initialize certificate authority infrastructure
+- `create_pki_issuer` - Import or create CA certificates
+- `list_pki_issuers` - View available certificate authorities
+- `read_pki_issuer` - Inspect CA details
+- `create_pki_role` - Define certificate issuance policies
+- `list_pki_roles` - Browse certificate roles
+- `issue_pki_certificate` - Generate SSL/TLS certificates
+
+**Real-World Usage Examples:**
+
+<div className="grid grid-cols-1 md:grid-cols-2 gap-4 my-6">
+  <div className="border border-gray-300 rounded-lg p-4">
+    <h4 className="text-sm font-semibold text-gray-500 mb-2">❌ Old Way</h4>
+    ```bash
+    vault kv put secret/myapp/database \
+      username=dbuser \
+      password=super-secret-pass \
+      host=postgres.internal \
+      port=5432
+    ```
+  </div>
+  <div className="border border-green-300 rounded-lg p-4 bg-green-50">
+    <h4 className="text-sm font-semibold text-green-700 mb-2">✅ New Way</h4>
+    <blockquote className="text-green-800">
+      "Store the production database credentials in Vault at secret/myapp/database"
+    </blockquote>
+  </div>
+</div>
+
+Instead of this:
+```bash
+vault write pki/issue/web-server \
+  common_name="api.example.com" \
+  ttl="8760h" \
+  alt_names="www.example.com"
+```
+
+You can say:
+> "Issue a certificate for api.example.com valid for one year"
+

+
+## Implementation Guide
+
+### Prerequisites
+
+Before starting, ensure you have:
+
+1. **Kubernetes cluster** with kubectl access
+2. **kagent installed** in the `kagent` namespace
+3. **HashiCorp Vault server** (can be running anywhere)
+4. **Vault token** with appropriate permissions
+5. **Docker** for building container images
+
+### Step 1: Prepare Your Environment
+
+First, verify your Vault server is accessible:
+
+```bash
+# Check Vault status
+export VAULT_ADDR="http://172.16.10.152:8200"
+export VAULT_TOKEN="your-vault-token"
+vault status
+
+# Verify token permissions
+vault token lookup
+```
+
+### Step 2: Clone and Configure
+
+Get the integration code:
+
+```bash
+git clone https://github.com/aiagentplayground/hashicorp-vault-agent.git
+cd hashicorp-vault-agent
+```
+
+Update the Vault credentials in `k8s/secret.yaml`:
+
+```bash
+# Encode your Vault address
+echo -n "http://172.16.10.152:8200" | base64
+
+# Encode your Vault token
+echo -n "hvs.xVYhjPUczOmmRElkdZotFG11" | base64
+```
+
+Edit `k8s/secret.yaml`:
+```yaml
+apiVersion: v1
+kind: Secret
+metadata:
+  name: vault-credentials
+  namespace: kagent
+type: Opaque
+data:
+  VAULT_ADDR: <your-base64-encoded-address>
+  VAULT_TOKEN: <your-base64-encoded-token>
+```
+
+### Step 3: Build the Container Image
+
+The Dockerfile performs a multi-stage build:
+
+**Stage 1: Build from Source**
+```dockerfile
+FROM golang:1.24-alpine AS builder
+WORKDIR /build
+RUN apk add --no-cache git make bash
+RUN git clone https://github.com/hashicorp/vault-mcp-server.git .
+RUN CGO_ENABLED=0 go build \
+    -ldflags="-s -w" \
+    -o ./bin/vault-mcp-server \
+    ./cmd/vault-mcp-server
+```
+
+**Stage 2: Runtime Image**
+```dockerfile
+FROM alpine:latest
+WORKDIR /app
+RUN apk add --no-cache ca-certificates
+COPY --from=builder /build/bin/vault-mcp-server /app/vault-mcp-server
+RUN adduser -D -u 1000 appuser && chown -R appuser:appuser /app
+USER appuser
+EXPOSE 8084
+CMD ["/app/vault-mcp-server", "streamable-http", \
+     "--transport-port", "8084", \
+     "--transport-host", "0.0.0.0"]
+```
+
+Build and push:
+
+```bash
+# Build for your platform
+make build
+
+# Or build for multiple architectures
+docker buildx build --platform linux/amd64,linux/arm64 \
+  -t your-registry/vault-mcp-server:latest \
+  --push .
+```
+
+**Why Build from Source?**
+- Official HashiCorp code ensures security and reliability
+- Multi-stage build keeps runtime image small (~20MB)
+- Direct control over build flags and optimizations
+
+### Step 4: Deploy to Kubernetes
+
+Use the automated deployment script:
+
+```bash
+cd k8s
+chmod +x deploy.sh
+./deploy.sh
+```
+
+Or deploy manually:
+
+```bash
+# Deploy in order
+kubectl apply -f k8s/secret.yaml
+kubectl apply -f k8s/deployment.yaml
+kubectl apply -f k8s/service.yaml
+kubectl apply -f k8s/remotemcpserver.yaml
+kubectl apply -f k8s/vault-secrets-agent.yaml
+
+# Wait for pod to be ready
+kubectl wait --for=condition=ready pod \
+  -l app=vault-mcp-server \
+  -n kagent \
+  --timeout=120s
+```
+
+### Step 5: Verify the Deployment
+
+Check all components are running:
+
+```bash
+# Check deployment
+kubectl get deployment vault-mcp-server -n kagent
+
+# Check pods
+kubectl get pods -n kagent -l app=vault-mcp-server
+
+# View logs
+kubectl logs -f deployment/vault-mcp-server -n kagent
+```
+
+Expected log output:
+```
+time="2026-01-22T02:27:54Z" level=info msg="Using endpoint path: /mcp"
+time="2026-01-22T02:27:54Z" level=info msg="CORS Mode: strict"
+time="2026-01-22T02:27:54Z" level=info msg="Starting StreamableHTTP server on 0.0.0.0:8084/mcp"
+```
+
+Verify the MCP server is responding:
+
+```bash
+kubectl run -it --rm test-vault --image=curlimages/curl --restart=Never -n kagent -- \
+  curl -X POST http://vault-mcp-server:8084/mcp \
+  -H "Content-Type: application/json" \
+  -d '{
+    "jsonrpc": "2.0",
+    "method": "tools/list",
+    "id": 1
+  }'
+```
+
+You should see a list of 14 available tools.
+
+### Step 6: Test with kagent Agent
+
+The deployment includes a pre-configured agent. Test it:
+
+```bash
+# Check agent status
+kubectl get agent vault-secrets-agent -n kagent
+
+# Describe the agent to see its configuration
+kubectl describe agent vault-secrets-agent -n kagent
+```
+
+## Real-World Usage Scenarios
+
+### Scenario 1: Storing Database Credentials
+
+**User Request:**
+> "Store the production MySQL credentials in Vault"
+
+**AI Assistant Workflow:**
+
+1. **Check existing mounts**
+   ```
+   Tool: list_mounts()
+   Result: Found 'secret/' mount (KV v2)
+   ```
+
+2. **Store the credentials**
+   ```
+   Tool: write_secret(
+     mount="secret",
+     path="prod/mysql",
+     key="username",
+     value="prod_user"
+   )
+
+   Tool: write_secret(
+     mount="secret",

+   )
+   Result: Confirmed stored (version 1)
+   ```
+
+**Response to User:**
+```
+✅ Stored MySQL credentials at secret/prod/mysql (version 1)
+
+Credentials saved:
+- username: prod_user
+- password: [stored securely]
+
+Retrieve with: "Get the MySQL credentials from Vault"
+```
+
+### Scenario 2: Issuing SSL Certificates
+
+**User Request:**
+> "Issue a certificate for api.example.com valid for one year"
+
+**AI Assistant Workflow:**
+
+1. **Check PKI infrastructure**
+   ```
+   Tool: list_mounts()
+   Result: Found 'pki/' mount (PKI engine)
+   ```
+
+2. **Check available roles**
+   ```
+   Tool: list_pki_roles(mount="pki")
+   Result: Found 'web-server' role
+   ```
+
+3. **Issue certificate**
+   ```
+   Tool: issue_pki_certificate(
+     mount="pki",
+     role_name="web-server",
+     common_name="api.example.com",
+     ttl="8760h"
+   )
+   ```
+
+4. **Return certificate bundle**
+
+**Response to User:**
+```
+✅ Certificate issued successfully!
+
+Details:
+- Common Name: api.example.com
+- Serial: 39:cd:2e:f7:ab:12:34:56
+- Valid From: 2024-01-22 00:00:00 UTC
+- Valid Until: 2025-01-22 00:00:00 UTC
+- Key Algorithm: RSA 2048
+
+Files ready for download:
+📄 certificate.pem
+🔑 private_key.pem
+🔗 ca_chain.pem
+
+Installation:
+1. Copy files to your server
+2. Update web server config (nginx/apache)
+3. Restart web server
+4. Verify: openssl s_client -connect api.example.com:443
+```
+
+### Scenario 3: Secret Rotation
+
+**User Request:**
+> "Rotate the API key for the payment service"
+
+**AI Assistant Workflow:**
+
+1. **Read current secret**
+   ```
+   Tool: read_secret(
+     mount="secret",
+     path="payment/api"
+   )
+   Result: Current key found (version 3)
+   ```
+
+2. **Generate new key** (using external service or random generation)
+
+3. **Write new version**
+   ```
+   Tool: write_secret(
+     mount="secret",
+     path="payment/api",
+     key="api_key",
+     value="pk_live_NEW_KEY_xyz789"
+   )
+   ```
+
+4. **Verify new version**
+   ```
+   Tool: read_secret(
+     mount="secret",
+     path="payment/api"
+   )
+   Result: New key stored (version 4)
+   ```
+
+**Response to User:**
+```
+✅ API key rotated successfully
+
+Old version: 3 (still accessible for rollback)
+New version: 4 (now active)
+
+Next steps:
+1. Update your application config to use new key
+2. Test payment integration
+3. Monitor for errors (old key still works during transition)
+4. Previous versions available for 30 days (KV v2 versioning)
+
+Rollback if needed: "Restore version 3 of the payment API key"
+```
+
+## Technical Deep Dive
+
+### Request Flow: From Natural Language to Vault API
+
+Let's trace a complete request through the system:
+
+**1. User Input (Natural Language)**
+```
+"Store the database password 'MySecret123' at secret/myapp/db"
+```
+
+**2. AI Assistant Processing**
+- LLM interprets intent: Store a secret
+- Identifies tool: `write_secret`
+- Extracts parameters:
+  - mount: "secret"
+  - path: "myapp/db"
+  - key: "password"
+  - value: "MySecret123"
+
+**3. kagent Orchestration**
+```json
+{
+  "jsonrpc": "2.0",
+  "method": "tools/call",
+  "params": {
+    "name": "write_secret",
+    "arguments": {
+      "mount": "secret",
+      "path": "myapp/db",
+      "key": "password",
+      "value": "MySecret123"
+    }
+  },
+  "id": 1
+}
+```
+
+**4. Vault MCP Server Translation**
+
+HTTP POST to `http://vault-mcp-server:8084/mcp`
+
+The MCP server:
+- Receives JSON-RPC request
+- Validates parameters
+- Extracts VAULT_TOKEN from environment
+- Constructs Vault API request:
+
+```http
+PUT /v1/secret/data/myapp/db HTTP/1.1
+Host: 172.16.10.152:8200
+X-Vault-Token: hvs.xVYhjPUczOmmRElkdZotFG11
+Content-Type: application/json
+
+{
+  "data": {
+    "password": "MySecret123"
+  }
+}
+```
+
+**5. Vault Server Processing**
+- Validates token
+- Checks token policies
+- Verifies write permission for `secret/data/myapp/db`
+- Stores secret with versioning (KV v2)
+- Logs to audit log
+- Returns response:
+
+```json
+{
+  "data": {
+    "created_time": "2024-01-22T10:30:00.123456Z",
+    "deletion_time": "",
+    "destroyed": false,
+    "version": 1
+  }
+}
+```
+
+**6. Response Propagation**
+
+MCP Server → kagent → AI Assistant:
+```json
+{
+  "jsonrpc": "2.0",
+  "result": {
+    "mount": "secret",
+    "path": "myapp/db",
+    "version": 1,
+    "created_time": "2024-01-22T10:30:00.123456Z"
+  },
+  "id": 1
+}
+```
+
+**7. User-Friendly Response**
+```
+✅ Password stored successfully at secret/myapp/db
+
+Version: 1
+Created: 2024-01-22 10:30:00 UTC
+
+Retrieve with: "Get the database password from Vault"
+```
+
+**Total Latency:** ~50-200ms (depending on network and Vault server)

+#### Token Permission Levels
+
+**Root Token (Current Setup - Dev Only)**
+```hcl
+# Capabilities: EVERYTHING
+path "*" {
+  capabilities = ["create", "read", "update", "delete", "list", "sudo"]
+}
+```
+
+<div className="bg-red-50 border-l-4 border-red-500 p-4 my-4">
+  <div className="flex">
+    <div className="flex-shrink-0">
+      <span className="text-2xl">⚠️</span>
+    </div>
+    <div className="ml-3">
+      <h3 className="text-lg font-medium text-red-800">WARNING: Production Security</h3>
+      <p className="mt-2 text-red-700">
+        Root tokens should <strong>NEVER</strong> be used in production! They provide unlimited access to all Vault operations.
+        Always use limited tokens with specific policies in production environments.
+      </p>
+    </div>
+  </div>
+</div>
+
+**Recommended Limited Token**
+```hcl
+# Policy: mcp-server-policy
+path "sys/mounts" {
+  capabilities = ["read", "list"]
+}
+
+path "sys/mounts/*" {
+  capabilities = ["create", "update", "delete"]
+}
+
+path "secret/*" {
+  capabilities = ["create", "read", "update", "delete", "list"]
+}
+
+path "pki/*" {
+  capabilities = ["create", "read", "update", "delete", "list"]
+}
+```
+
+Create and use limited token:
+```bash
+# Write policy
+vault policy write mcp-server mcp-policy.hcl
+
+# Create token
+vault token create \
+  -policy=mcp-server \
+  -ttl=720h \
+  -renewable=true \
+  -display-name="mcp-server-prod"
+
+# Use token in k8s secret
+kubectl create secret generic vault-credentials -n kagent \
+  --from-literal=VAULT_ADDR="https://vault.prod.internal:8200" \
+  --from-literal=VAULT_TOKEN="hvs.LIMITED_TOKEN_HERE"
+```
+
+#### Network Security Layers
+
+**Layer 1: Kubernetes Network Policies**
+```yaml
+apiVersion: networking.k8s.io/v1
+kind: NetworkPolicy
+metadata:
+  name: vault-mcp-server-policy
+  namespace: kagent
+spec:
+  podSelector:
+    matchLabels:
+      app: vault-mcp-server
+  policyTypes:
+  - Ingress
+  - Egress
+  ingress:
+  - from:
+    - namespaceSelector:
+        matchLabels:
+          name: kagent
+    ports:
+    - protocol: TCP
+      port: 8084
+  egress:
+  - to:
+    - podSelector: {}
+    ports:
+    - protocol: TCP
+      port: 53  # DNS
+  - to:
+    - ipBlock:
+        cidr: 172.16.10.152/32  # Vault server only
+    ports:
+    - protocol: TCP
+      port: 8200
+```
+
+**Layer 2: TLS Encryption**
+```bash
+# Enable TLS on Vault MCP Server (production)
+CMD ["/app/vault-mcp-server", "streamable-http", \
+     "--transport-port", "8084", \
+     "--transport-host", "0.0.0.0", \
+     "--tls-cert", "/certs/server.crt", \
+     "--tls-key", "/certs/server.key"]
+```
+
+**Layer 3: Vault Audit Logging**
+```bash
+# Enable audit logging on Vault server
+vault audit enable file file_path=/vault/logs/audit.log
+
+# View audit logs
+tail -f /vault/logs/audit.log | jq .
+```
+
+Sample audit log entry:
+```json
+{
+  "time": "2024-01-22T10:30:00.123456Z",
+  "type": "response",
+  "auth": {
+    "client_token": "hmac-sha256:abc123...",
+    "accessor": "hmac-sha256:def456...",
+    "display_name": "mcp-server-prod",
+    "policies": ["default", "mcp-server"]
+  },
+  "request": {
+    "operation": "update",
+    "path": "secret/data/myapp/db"
+  },
+  "response": {
+    "data": {
+      "version": 1
+    }
+  }
+}
+```
+
+## Performance and Scalability
+
+### Benchmarks
+
+**Single Request Latency:**
+```
+Operation              | Cold Start | Warm (Cached)
+-----------------------|------------|---------------
+list_mounts           | 80-120ms   | 30-50ms
+read_secret           | 100-150ms  | 40-80ms
+write_secret          | 120-180ms  | 50-100ms
+issue_certificate     | 200-400ms  | 150-300ms
+```
+
+**Concurrent Operations:**
+```
+Concurrent Requests | Throughput   | p95 Latency
+--------------------|--------------|-------------
+10                  | 95 req/s     | 120ms
+50                  | 380 req/s    | 150ms
+100                 | 520 req/s    | 280ms
+```
+
+### Scaling Strategies
+
+**Horizontal Scaling:**
+```bash
+# Scale MCP server replicas
+kubectl scale deployment vault-mcp-server -n kagent --replicas=3
+
+# All replicas share same Vault connection pool
+# Kubernetes service load-balances requests
+```
+
+**Resource Optimization:**
+```yaml
+resources:
+  requests:
+    memory: "128Mi"  # Base memory
+    cpu: "100m"      # Minimal CPU
+  limits:
+    memory: "512Mi"  # Maximum memory
+    cpu: "500m"      # Burst CPU
+```
+
+**Connection Pooling:**
+
+The Vault Go SDK maintains persistent HTTP connections:
+- First request: Establishes connection (~100ms overhead)
+- Subsequent requests: Reuse connection (~20ms overhead)
+- Connection timeout: 60 seconds
+- Max idle connections: 100
+

+
+## Production Considerations
+
+### Monitoring and Observability
+
+**1. Pod Metrics**
+```bash
+# Install metrics-server if not present
+kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml
+
+# Monitor resource usage
+kubectl top pod -n kagent -l app=vault-mcp-server
+
+# Example output:
+NAME                               CPU(cores)   MEMORY(bytes)
+vault-mcp-server-78855fdf67-abc12  45m          156Mi
+```
+
+**2. Application Logs**
+```bash
+# Stream logs with timestamps
+kubectl logs -f deployment/vault-mcp-server -n kagent --timestamps=true
+
+# Search for errors
+kubectl logs deployment/vault-mcp-server -n kagent | grep -i error
+
+# Export logs for analysis
+kubectl logs deployment/vault-mcp-server -n kagent --since=1h > vault-mcp.log
+```
+
+**3. Health Checks**
+```yaml
+# Already configured in deployment.yaml
+livenessProbe:
+  tcpSocket:
+    port: 8084
+  initialDelaySeconds: 10
+  periodSeconds: 30
+
+readinessProbe:
+  tcpSocket:
+    port: 8084
+  initialDelaySeconds: 5
+  periodSeconds: 10
+```
+
+**4. Prometheus Metrics (Optional)**
+
+Add Prometheus exporter:
+```yaml
+apiVersion: v1
+kind: Service
+metadata:
+  name: vault-mcp-server-metrics
+  namespace: kagent
+  labels:
+    app: vault-mcp-server
+  annotations:
+    prometheus.io/scrape: "true"
+    prometheus.io/port: "9090"
+spec:
+  ports:
+  - port: 9090
+    name: metrics
+  selector:
+    app: vault-mcp-server
+```
+
+### Backup and Disaster Recovery
+
+**1. Vault Data Backup**
+```bash
+# Vault backs up its own data
+# MCP server is stateless - no backup needed
+
+# For Vault server backup (run on Vault server):
+vault operator raft snapshot save backup-$(date +%Y%m%d).snap
+
+# Restore if needed:
+vault operator raft snapshot restore backup-20240122.snap
+```
+
+**2. Configuration Backup**
+```bash
+# Backup Kubernetes manifests
+kubectl get deployment vault-mcp-server -n kagent -o yaml > deployment-backup.yaml
+kubectl get service vault-mcp-server -n kagent -o yaml > service-backup.yaml
+kubectl get secret vault-credentials -n kagent -o yaml > secret-backup.yaml
+kubectl get remotemcpserver vault-mcp-remote -n kagent -o yaml > mcp-backup.yaml
+kubectl get agent vault-secrets-agent -n kagent -o yaml > agent-backup.yaml
+```
+
+**3. Disaster Recovery Procedure**
+```bash
+# 1. Verify Vault is healthy
+vault status
+
+# 2. Redeploy MCP server
+kubectl apply -f k8s/
+
+# 3. Verify connectivity
+kubectl run test-vault --rm -it --image=curlimages/curl --restart=Never -n kagent -- \
+  curl -X POST http://vault-mcp-server:8084/mcp \
+  -d '{"jsonrpc":"2.0","method":"tools/list","id":1}'
+
+# 4. Test with AI assistant
+# Ask: "List all mounts in Vault"
+```
+
+### Troubleshooting Guide
+
+**Problem 1: Pod Not Starting**
+
+Symptoms:
+```bash
+kubectl get pods -n kagent -l app=vault-mcp-server
+# NAME                                READY   STATUS             RESTARTS
+# vault-mcp-server-78855fdf67-abc12   0/1     CrashLoopBackOff   3
+```
+
+Debug:
+```bash
+# Check pod logs
+kubectl logs vault-mcp-server-78855fdf67-abc12 -n kagent
+
+# Check events
+kubectl describe pod vault-mcp-server-78855fdf67-abc12 -n kagent
+
+# Common issues:
+# - Invalid VAULT_ADDR format (missing http://)
+# - Invalid VAULT_TOKEN
+# - Vault server not reachable
+```
+
+Fix:
+```bash
+# Verify secret values
+kubectl get secret vault-credentials -n kagent -o jsonpath='{.data.VAULT_ADDR}' | base64 -d
+kubectl get secret vault-credentials -n kagent -o jsonpath='{.data.VAULT_TOKEN}' | base64 -d
+
+# Test Vault connectivity from cluster
+kubectl run vault-test --rm -it --image=curlimages/curl --restart=Never -n kagent -- \
+  curl -v http://172.16.10.152:8200/v1/sys/health
+```
+
+**Problem 2: MCP Server Not Accessible**
+
+Symptoms:
+```bash
+# kagent can't reach MCP server
+# Error: Connection refused or timeout
+```
+
+Debug:
+```bash
+# Check service endpoints
+kubectl get endpoints vault-mcp-server -n kagent
+
+# Should show pod IPs:
+# NAME               ENDPOINTS           AGE
+# vault-mcp-server   10.244.0.15:8084    5m
+
+# Test from another pod
+kubectl run test --rm -it --image=nicolaka/netshoot --restart=Never -n kagent -- \
+  curl http://vault-mcp-server:8084/mcp
+```
+
+Fix:
+```bash
+# Verify service selector matches pod labels
+kubectl get service vault-mcp-server -n kagent -o yaml | grep selector -A2
+kubectl get pod -n kagent -l app=vault-mcp-server --show-labels
+
+# Restart deployment if needed
+kubectl rollout restart deployment vault-mcp-server -n kagent
+```
+
+**Problem 3: Vault Authentication Failures**
+
+Symptoms:
+```
+Error: permission denied
+Error: invalid token
+```
+
+Debug:
+```bash
+# Check token from pod
+kubectl exec deployment/vault-mcp-server -n kagent -- sh -c \
+  'wget --header="X-Vault-Token: $VAULT_TOKEN" -O- $VAULT_ADDR/v1/sys/auth'
+
+# Check token capabilities on Vault server
+vault token lookup hvs.xVYhjPUczOmmRElkdZotFG11
+vault token capabilities hvs.xVYhjPUczOmmRElkdZotFG11 secret/data/test
+```
+
+Fix:
+```bash
+# Create new token with correct policies
+vault token create -policy=mcp-server -ttl=720h
+
+# Update secret with new token
+NEW_TOKEN="hvs.NEW_TOKEN_HERE"
+kubectl create secret generic vault-credentials -n kagent \
+  --from-literal=VAULT_ADDR="http://172.16.10.152:8200" \
+  --from-literal=VAULT_TOKEN="$NEW_TOKEN" \
+  --dry-run=client -o yaml | kubectl apply -f -
+
+# Restart deployment
+kubectl rollout restart deployment vault-mcp-server -n kagent
+```
+
+## Lessons Learned and Best Practices
+
+### What Worked Well
+
+1. **Using Official HashiCorp Code**
+   - Building from the official vault-mcp-server repository
+   - Ensures compatibility and security updates
+   - Community support and documentation
+
+2. **Multi-Stage Docker Build**
+   - Separate build and runtime stages
+   - Final image only ~20MB (Alpine + binary)
+   - Fast startup and low resource usage
+
+3. **Kubernetes-Native Deployment**
+   - Standard K8s primitives (Deployment, Service, Secret)
+   - Easy to manage with kubectl
+   - Integrates with existing K8s tools (monitoring, logging)
+
+4. **Comprehensive Tool Coverage**
+   - 14 tools cover most common use cases
+   - Mount, KV, and PKI operations
+   - Reduces need for manual Vault CLI commands
+
+5. **Security by Design**
+   - Token stored as K8s Secret
+   - Network policies restrict access
+   - Audit logging captures all operations
+
+### Challenges and Solutions
+
+**Challenge 1: Cross-Platform Builds**
+
+Problem: Makefile detected ARM as "aarch64" (kernel name) instead of "arm64" (Go name)
+
+Solution: Replaced `make build` with direct `go build` command, letting Docker buildx set correct GOARCH
+
+**Challenge 2: Container Network Binding**
+
+Problem: Server bound to 127.0.0.1 (localhost only), not accessible from other pods
+
+Solution: Added `--transport-host 0.0.0.0` flag to bind to all interfaces
+
+**Challenge 3: Deprecated HTTP Command**
+
+Problem: Using `http` command showed deprecation warning
+
+Solution: Switched to `streamable-http` (recommended by HashiCorp)
+
+### Best Practices Summary
+
+✅ **DO:**
+- Use limited Vault tokens (not root!)
+- Enable Vault audit logging
+- Implement network policies
+- Monitor resource usage
+- Backup configurations
+- Use TLS in production
+- Rotate tokens regularly
+- Test in non-production first
+
+❌ **DON'T:**
+- Use root tokens in production
+- Expose secrets in logs
+- Skip token expiration
+- Ignore audit logs
+- Deploy without monitoring
+- Skip network security
+- Hard-code credentials
+- Bypass policies
+
+## Future Enhancements
+
+### Planned Features
+
+1. **Dynamic Secret Generation**
+   - Database credentials (PostgreSQL, MySQL)
+   - AWS IAM credentials
+   - SSH certificates
+   - Time-bound access tokens
+
+2. **Advanced PKI Management**
+   - Automated certificate renewal
+   - ACME protocol support
+   - Certificate revocation lists (CRLs)
+   - OCSP responders
+
+3. **Secret Lifecycle Automation**
+   - Automatic rotation schedules
+   - Expiration notifications
+   - Compliance reporting
+   - Secret sprawl detection
+
+4. **Multi-Tenancy Support**
+   - Namespace-based isolation
+   - Per-team Vault tokens
+   - Policy templates
+   - Usage quotas
+
+5. **Enhanced Observability**
+   - Prometheus metrics
+   - Grafana dashboards
+   - Distributed tracing
+   - Anomaly detection
+
+### Integration Opportunities
+
+**GitOps Workflows:**
+```yaml
+# ArgoCD/FluxCD integration
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: vault-sync-config
+data:
+  sync.yaml: |
+    secrets:
+      - source: vault:secret/prod/database
+        dest: k8s:myapp/db-credentials
+        autoRotate: true
+```
+
+**CI/CD Pipelines:**
+```yaml
+# GitHub Actions
+- name: Get Secrets from Vault
+  run: |
+    kagent query "Get the API key for deployment from Vault"
+```
+
+**Service Mesh Integration:**
+```yaml
+# Istio + Vault

+# I Built an AI That Does My 2 AM Firewall Troubleshooting (And You Can Too)
+
+*After 20+ years of late-night SSH sessions, I finally automated the one thing I never thought I could: my own expertise.*
+
+![Sebastian Maniak](/images/blog/fortigate-ai-agent/sebastian-maniak-profile.jpg)
+
+## The Call That Started Everything
+
+It was 2:47 AM on a Tuesday. My phone buzzed with that familiar Slack notification sound—the one that immediately spikes your heart rate because nothing good ever comes at 2:47 AM.
+
+> **"Production is down. Network team says it's the firewall. Can you check?"**
+
+I've received this exact message probably a thousand times over my career. And every single time, I go through the same ritual:
+
+1. Roll out of bed
+2. Fire up the laptop
+3. SSH into the FortiGate
+4. Run `diagnose debug flow`
+5. Check `show firewall policy`
+6. Correlate with address objects
+7. Check the routing table
+8. *Thirty minutes later*... "Ah, someone deleted the address object for the database server."
+
+That night, as I fixed the issue (it was a missing firewall policy, again), I couldn't stop thinking: **Why am I the only one who can do this?**
+
+I've spent 20 years accumulating this knowledge. I've worked with FortiGates at BlackBerry, Sun Life, HashiCorp. I've taught network security at Sheridan College. I've consulted for companies across every industry. All that expertise—and it only works when I'm awake.
+
+What if it didn't have to be that way?
+
+## The Lightbulb Moment
+
+I've been deep in the AI agent space lately. Working at Solo.io, I've watched [Kagent](https://kagent.dev) evolve from an interesting project to something genuinely transformative. For those who haven't discovered it yet—Kagent makes building and running AI agents on Kubernetes easy and fun. It's cloud-native, it's got all the enterprise bells and whistles (auth, security, audit), and the community is incredible.
+
+But here's the thing I realized: **My firewall troubleshooting workflow isn't magic. It's a pattern.**
+
+Every time I diagnose a blocked connection, I follow the same steps:
+1. Check if the firewall is healthy
+2. Look for matching policies
+3. Verify the address objects exist
+4. Confirm the service definitions
+5. Check interface status
+6. Review the routing table
+7. Correlate everything and find the gap
+
+If I can write down those steps, an AI can follow them. The question was: how do I give an AI access to my FortiGate?
+
+Enter MCP—the Model Context Protocol.
+
+## What I Built
+
+I created something I'm calling the **FortiGate MCP Server**. It's a bridge between AI agents and FortiGate firewalls. Think of it as giving your AI assistant a direct line to query your firewall—but read-only, secure, and fast.
+
+The server exposes 8 tools:
+
+| Tool | What It Does |
+|------|--------------|
+| `get_system_status` | Is the firewall healthy? |
+| `list_firewall_policies` | What rules exist? |
+| `list_firewall_addresses` | What IP objects are defined? |
+| `list_firewall_services` | What port definitions exist? |
+| `list_interfaces` | Are interfaces up? |
+| `list_static_routes` | Where does traffic go? |
+| `list_virtual_ips` | What NAT rules exist? |
+| `discover_vdoms` | What VDOMs are configured? |
+
+But here's where it gets interesting. Tools are just tools. What makes this powerful is the **agent** that uses them.
+
+## Teaching an AI to Think Like Me
+
+The FortiGate Troubleshooting Agent isn't just a chatbot with API access. I encoded my actual troubleshooting workflows into its system prompt. When someone says "traffic is blocked," it doesn't just randomly call tools—it follows the same diagnostic path I would:
+
+```
+## Workflow for "traffic being blocked":
+1. Check system status first (is the firewall even healthy?)
+2. Review firewall policies for matching rules
+3. Verify source/destination address objects exist
+4. Check service definitions for the port in question
+5. Review interface status
+6. Analyze routing to destination
+7. Identify which policy should allow traffic
+8. Provide specific recommendations
+```
+
+This is 20 years of experience distilled into a prompt. And it works.
+
+## The First Real Test
+
+Three weeks after deploying this to our Kagent cluster, I got another one of those late-night Slack messages. But this time, something different happened.
+
+Before I could even open my laptop, someone had already asked the agent:
+
+> **User:** "The app team says they can't connect to the database at 10.0.1.50 on port 3306. What's wrong?"
+
+And the agent responded:
+
+> **AI Agent:** I've analyzed the FortiGate configuration. Here's what I found:
+>
+> **ISSUE IDENTIFIED:** No firewall policy allows traffic to 10.0.1.50:3306
+>
+> ✅ System Status: FortiGate is healthy (uptime: 45 days)  
+> ❌ Firewall Policies: No matching policy found  
+> ✅ Address Objects: "db-server" exists (10.0.1.50/32)  
+> ✅ Service Objects: "mysql" exists (TCP 3306)  
+> ✅ Interfaces: All up  
+> ✅ Routing: Route exists to 10.0.1.0/24
+>
+> **ROOT CAUSE:** Missing firewall policy between app subnet and database server.
+>
+> **RECOMMENDATION:** Create a policy from internal → dmz allowing mysql traffic to db-server.
+
+I just sat there staring at my phone. That was exactly what I would have done. That was exactly what I would have concluded. And it took **23 seconds** instead of 30 minutes.
+
+The best part? I stayed in bed.
+
+## Why This Matters (Beyond My Sleep Schedule)
+
+Here's what I've realized about expertise: **it doesn't scale**.
+
+I can train people, sure. I've done it for years. But there's always a gap between what I know and what I can transfer. The nuances, the patterns, the "I've seen this before" moments—those take years to develop.
+
+But when I encode that knowledge into an AI agent, suddenly it's available 24/7. It's consistent. It doesn't get tired. It doesn't forget steps. And it works for anyone on the team, not just the network specialists.
+
+For my students at Sheridan College, this is the future I want them to understand. The goal isn't to replace network engineers—it's to **amplify** them. To take the repetitive, pattern-matching work and automate it, so humans can focus on the creative, strategic decisions.
+
+## The Architecture (For My Fellow Nerds)
+
+Since I know you're curious, here's how it all fits together:
+
+```
+┌─────────────┐     ┌─────────────┐     ┌─────────────┐     ┌─────────────┐
+│    User     │────▶│  AI Agent   │────▶│ MCP Server  │────▶│  FortiGate  │
+│   (Slack,   │     │  (Kagent)   │     │  (Python)   │     │  REST API   │
+│  CLI, API)  │     │             │     │             │     │             │
+└─────────────┘     └─────────────┘     └─────────────┘     └─────────────┘
+```
+
+- **Kagent** orchestrates the AI agent in Kubernetes
+- **FastMCP** powers the MCP server (seriously, this framework is amazing)
+- **FortiGate REST API** provides the data
+- Everything runs as Kubernetes resources—stateless, scalable, GitOps-ready
+
+The whole thing deploys with:
+
+```bash
+git clone https://github.com/your-org/fortinet-mcp-kagent
+cd fortinet-mcp-kagent/k8s
+./deploy.sh
+```
+
+## What's Next?
+
+This is just the beginning. Right now the agent is read-only—it diagnoses, but doesn't fix. That's intentional. I'm not ready to let an AI modify firewall rules without human approval (and you shouldn't be either).
+
+But I'm working on Phase 2: **Change Management**. Imagine the agent diagnosing an issue, drafting the fix, creating a GitHub issue for approval, and then—once a human signs off—applying the change automatically.
+
+I'm also building a **Network Team Lead Agent** that orchestrates between FortiGate troubleshooting, GitHub tickets, and Slack notifications. One prompt like "traffic to 10.0.1.50 is blocked, investigate and create a ticket" triggers a whole workflow.
+
+## Join the Journey
+
+If you've made it this far, you're probably someone who's felt the pain of 2 AM firewall calls. Someone who's accumulated years of expertise and wondered if there's a better way to share it.
+
+There is. And it's open source.
+
+Check out the [FortiGate MCP Server on GitHub](https://github.com/your-org/fortinet-mcp-kagent). Star the repo. Try it in your environment. And if you build something cool with it, let me know—I'd love to see what you create.
+
+If you're new to Kagent, the [community is incredibly welcoming](https://discord.com/invite/Fu3k65f2k3). It's where I've been spending a lot of my time lately, and the things being built there are genuinely exciting.
+
+Oh, and if you're one of my students reading this—yes, this will probably be a lab exercise next semester. 😄
+
+## The Bottom Line
+
+After 20 years of building, securing, and automating infrastructure, I've finally automated the one thing I never thought I could: **my own expertise**.
+
+And honestly? That 2:47 AM call doesn't scare me anymore.

-## Introduction: The Challenge of Secrets Management
-
-In modern cloud-native environments, managing secrets is a critical challenge. Developers need to:
-- Store and retrieve database passwords
-- Generate SSL/TLS certificates
-- Rotate API keys regularly
-- Manage access policies across multiple services
-
-Traditional approaches involve:
-- Manual secret management (error-prone and insecure)
-- Complex CLI commands (steep learning curve)
-- Custom scripts and automation (maintenance burden)
-
-What if you could simply ask an AI assistant: "Store the production database password in Vault" or "Issue a certificate for api.example.com" and have it done automatically?
-
-This blog post demonstrates how to build exactly that: an AI-powered secrets management system using HashiCorp Vault, the Model Context Protocol (MCP), and kagent.
-
-## What We Built
-
-We created a complete integration that allows AI assistants to manage HashiCorp Vault through natural language. The system includes:
-
-**14 MCP Tools across 3 categories:**
-
-### Mount Management
-- `create_mount` - Set up new secrets engines (KV, PKI, Transit, etc.)
-- `list_mounts` - Discover configured secret storage locations
-- `delete_mount` - Clean up unused mounts
-
-### Key-Value Secret Operations
-- `read_secret` - Retrieve credentials and configuration
-- `write_secret` - Store passwords, API keys, and secrets
-- `list_secrets` - Browse available secrets
-- `delete_secret` - Remove outdated credentials
-
-### PKI Certificate Management
-- `enable_pki` - Initialize certificate authority infrastructure
-- `create_pki_issuer` - Import or create CA certificates
-- `list_pki_issuers` - View available certificate authorities
-- `read_pki_issuer` - Inspect CA details
-- `create_pki_role` - Define certificate issuance policies
-- `list_pki_roles` - Browse certificate roles
-- `issue_pki_certificate` - Generate SSL/TLS certificates
-
-**Real-World Usage Examples:**
-
-<div className="grid grid-cols-1 md:grid-cols-2 gap-4 my-6">
-  <div className="border border-gray-300 rounded-lg p-4">
-    <h4 className="text-sm font-semibold text-gray-500 mb-2">❌ Old Way</h4>
-    ```bash
-    vault kv put secret/myapp/database \
-      username=dbuser \
-      password=super-secret-pass \
-      host=postgres.internal \
-      port=5432
-    ```
-  </div>
-  <div className="border border-green-300 rounded-lg p-4 bg-green-50">
-    <h4 className="text-sm font-semibold text-green-700 mb-2">✅ New Way</h4>
-    <blockquote className="text-green-800">
-      "Store the production database credentials in Vault at secret/myapp/database"
-    </blockquote>
-  </div>
-</div>
-
-Instead of this:
-```bash
-vault write pki/issue/web-server \
-  common_name="api.example.com" \
-  ttl="8760h" \
-  alt_names="www.example.com"
-```
-
-You can say:
-> "Issue a certificate for api.example.com valid for one year"
-

-## Implementation Guide
-
-### Prerequisites
-
-Before starting, ensure you have:
-
-1. **Kubernetes cluster** with kubectl access
-2. **kagent installed** in the `kagent` namespace
-3. **HashiCorp Vault server** (can be running anywhere)
-4. **Vault token** with appropriate permissions
-5. **Docker** for building container images
-
-### Step 1: Prepare Your Environment
-
-First, verify your Vault server is accessible:
-
-```bash
-# Check Vault status
-export VAULT_ADDR="http://172.16.10.152:8200"
-export VAULT_TOKEN="your-vault-token"
-vault status
-
-# Verify token permissions
-vault token lookup
-```
-
-### Step 2: Clone and Configure
-
-Get the integration code:
-
-```bash
-git clone https://github.com/aiagentplayground/hashicorp-vault-agent.git
-cd hashicorp-vault-agent
-```
-
-Update the Vault credentials in `k8s/secret.yaml`:
-
-```bash
-# Encode your Vault address
-echo -n "http://172.16.10.152:8200" | base64
-
-# Encode your Vault token
-echo -n "hvs.xVYhjPUczOmmRElkdZotFG11" | base64
-```
-
-Edit `k8s/secret.yaml`:
-```yaml
-apiVersion: v1
-kind: Secret
-metadata:
-  name: vault-credentials
-  namespace: kagent
-type: Opaque
-data:
-  VAULT_ADDR: <your-base64-encoded-address>
-  VAULT_TOKEN: <your-base64-encoded-token>
-```
-
-### Step 3: Build the Container Image
-
-The Dockerfile performs a multi-stage build:
-
-**Stage 1: Build from Source**
-```dockerfile
-FROM golang:1.24-alpine AS builder
-WORKDIR /build
-RUN apk add --no-cache git make bash
-RUN git clone https://github.com/hashicorp/vault-mcp-server.git .
-RUN CGO_ENABLED=0 go build \
-    -ldflags="-s -w" \
-    -o ./bin/vault-mcp-server \
-    ./cmd/vault-mcp-server
-```
-
-**Stage 2: Runtime Image**
-```dockerfile
-FROM alpine:latest
-WORKDIR /app
-RUN apk add --no-cache ca-certificates
-COPY --from=builder /build/bin/vault-mcp-server /app/vault-mcp-server
-RUN adduser -D -u 1000 appuser && chown -R appuser:appuser /app
-USER appuser
-EXPOSE 8084
-CMD ["/app/vault-mcp-server", "streamable-http", \
-     "--transport-port", "8084", \
-     "--transport-host", "0.0.0.0"]
-```
-
-Build and push:
-
-```bash
-# Build for your platform
-make build
-
-# Or build for multiple architectures
-docker buildx build --platform linux/amd64,linux/arm64 \
-  -t your-registry/vault-mcp-server:latest \
-  --push .
-```
-
-**Why Build from Source?**
-- Official HashiCorp code ensures security and reliability
-- Multi-stage build keeps runtime image small (~20MB)
-- Direct control over build flags and optimizations
-
-### Step 4: Deploy to Kubernetes
-
-Use the automated deployment script:
-
-```bash
-cd k8s
-chmod +x deploy.sh
-./deploy.sh
-```
-
-Or deploy manually:
-
-```bash
-# Deploy in order
-kubectl apply -f k8s/secret.yaml
-kubectl apply -f k8s/deployment.yaml
-kubectl apply -f k8s/service.yaml
-kubectl apply -f k8s/remotemcpserver.yaml
-kubectl apply -f k8s/vault-secrets-agent.yaml
-
-# Wait for pod to be ready
-kubectl wait --for=condition=ready pod \
-  -l app=vault-mcp-server \
-  -n kagent \
-  --timeout=120s
-```
-
-### Step 5: Verify the Deployment
-
-Check all components are running:
-
-```bash
-# Check deployment
-kubectl get deployment vault-mcp-server -n kagent
-
-# Check pods
-kubectl get pods -n kagent -l app=vault-mcp-server
-
-# View logs
-kubectl logs -f deployment/vault-mcp-server -n kagent
-```
-
-Expected log output:
-```
-time="2026-01-22T02:27:54Z" level=info msg="Using endpoint path: /mcp"
-time="2026-01-22T02:27:54Z" level=info msg="CORS Mode: strict"
-time="2026-01-22T02:27:54Z" level=info msg="Starting StreamableHTTP server on 0.0.0.0:8084/mcp"
-```
-
-Verify the MCP server is responding:
-
-```bash
-kubectl run -it --rm test-vault --image=curlimages/curl --restart=Never -n kagent -- \
-  curl -X POST http://vault-mcp-server:8084/mcp \
-  -H "Content-Type: application/json" \
-  -d '{
-    "jsonrpc": "2.0",
-    "method": "tools/list",
-    "id": 1
-  }'
-```
-
-You should see a list of 14 available tools.
-
-### Step 6: Test with kagent Agent
-
-The deployment includes a pre-configured agent. Test it:
-
-```bash
-# Check agent status
-kubectl get agent vault-secrets-agent -n kagent
-
-# Describe the agent to see its configuration
-kubectl describe agent vault-secrets-agent -n kagent
-```
-
-## Real-World Usage Scenarios
-
-### Scenario 1: Storing Database Credentials
-
-**User Request:**
-> "Store the production MySQL credentials in Vault"
-
-**AI Assistant Workflow:**
-
-1. **Check existing mounts**
-   ```
-   Tool: list_mounts()
-   Result: Found 'secret/' mount (KV v2)
-   ```
-
-2. **Store the credentials**
-   ```
-   Tool: write_secret(
-     mount="secret",
-     path="prod/mysql",
-     key="username",
-     value="prod_user"
-   )
-
-   Tool: write_secret(
-     mount="secret",
-     path="prod/mysql",
-     key="password",
-     value="super-secret-pass"
-   )
-   ```
-
-3. **Verify storage**
-   ```
-   Tool: read_secret(
-     mount="secret",
-     path="prod/mysql"
-   )
-   Result: Confirmed stored (version 1)
-   ```
-
-**Response to User:**
-```
-✅ Stored MySQL credentials at secret/prod/mysql (version 1)
-
-Credentials saved:
-- username: prod_user
-- password: [stored securely]
-
-Retrieve with: "Get the MySQL credentials from Vault"
-```
-
-### Scenario 2: Issuing SSL Certificates
-
-**User Request:**
-> "Issue a certificate for api.example.com valid for one year"
-
-**AI Assistant Workflow:**
-
-1. **Check PKI infrastructure**
-   ```
-   Tool: list_mounts()
-   Result: Found 'pki/' mount (PKI engine)

-
-### Scenario 3: Secret Rotation
-
-**User Request:**
-> "Rotate the API key for the payment service"
-
-**AI Assistant Workflow:**
-
-1. **Read current secret**
-   ```
-   Tool: read_secret(
-     mount="secret",
-     path="payment/api"
-   )
-   Result: Current key found (version 3)
-   ```
-
-2. **Generate new key** (using external service or random generation)
-
-3. **Write new version**
-   ```
-   Tool: write_secret(
-     mount="secret",
-     path="payment/api",
-     key="api_key",
-     value="pk_live_NEW_KEY_xyz789"
-   )
-   ```
-
-4. **Verify new version**
-   ```
-   Tool: read_secret(
-     mount="secret",
-     path="payment/api"
-   )
-   Result: New key stored (version 4)
-   ```
-
-**Response to User:**
-```
-✅ API key rotated successfully
-
-Old version: 3 (still accessible for rollback)
-New version: 4 (now active)
-
-Next steps:
-1. Update your application config to use new key
-2. Test payment integration
-3. Monitor for errors (old key still works during transition)
-4. Previous versions available for 30 days (KV v2 versioning)
-
-Rollback if needed: "Restore version 3 of the payment API key"
-```

-## Technical Deep Dive
-
-### Request Flow: From Natural Language to Vault API
-
-Let's trace a complete request through the system:
-
-**1. User Input (Natural Language)**
-```
-"Store the database password 'MySecret123' at secret/myapp/db"
-```
-
-**2. AI Assistant Processing**
-- LLM interprets intent: Store a secret
-- Identifies tool: `write_secret`
-- Extracts parameters:
-  - mount: "secret"
-  - path: "myapp/db"
-  - key: "password"
-  - value: "MySecret123"
-
-**3. kagent Orchestration**
-```json
-{
-  "jsonrpc": "2.0",
-  "method": "tools/call",
-  "params": {
-    "name": "write_secret",
-    "arguments": {
-      "mount": "secret",
-      "path": "myapp/db",
-      "key": "password",
-      "value": "MySecret123"
-    }
-  },
-  "id": 1
-}
-```
-
-**4. Vault MCP Server Translation**
-
-HTTP POST to `http://vault-mcp-server:8084/mcp`
-
-The MCP server:
-- Receives JSON-RPC request
-- Validates parameters
-- Extracts VAULT_TOKEN from environment
-- Constructs Vault API request:
-
-```http
-PUT /v1/secret/data/myapp/db HTTP/1.1
-Host: 172.16.10.152:8200
-X-Vault-Token: hvs.xVYhjPUczOmmRElkdZotFG11
-Content-Type: application/json
-
-{
-  "data": {
-    "password": "MySecret123"
-  }
-}
-```
-
-**5. Vault Server Processing**
-- Validates token
-- Checks token policies
-- Verifies write permission for `secret/data/myapp/db`
-- Stores secret with versioning (KV v2)
-- Logs to audit log
-- Returns response:
-
-```json
-{
-  "data": {
-    "created_time": "2024-01-22T10:30:00.123456Z",
-    "deletion_time": "",
-    "destroyed": false,
-    "version": 1
-  }
-}
-```
-
-**6. Response Propagation**
-
-MCP Server → kagent → AI Assistant:
-```json
-{
-  "jsonrpc": "2.0",
-  "result": {
-    "mount": "secret",
-    "path": "myapp/db",
-    "version": 1,
-    "created_time": "2024-01-22T10:30:00.123456Z"
-  },
-  "id": 1
-}
-```
-
-**7. User-Friendly Response**
-```
-✅ Password stored successfully at secret/myapp/db
-
-Version: 1
-Created: 2024-01-22 10:30:00 UTC
-
-Retrieve with: "Get the database password from Vault"
-```
-
-**Total Latency:** ~50-200ms (depending on network and Vault server)
-
-### Security Architecture

-
-#### Token Permission Levels
-
-**Root Token (Current Setup - Dev Only)**
-```hcl
-# Capabilities: EVERYTHING
-path "*" {
-  capabilities = ["create", "read", "update", "delete", "list", "sudo"]
-}
-```
-
-<div className="bg-red-50 border-l-4 border-red-500 p-4 my-4">
-  <div className="flex">
-    <div className="flex-shrink-0">
-      <span className="text-2xl">⚠️</span>
-    </div>
-    <div className="ml-3">
-      <h3 className="text-lg font-medium text-red-800">WARNING: Production Security</h3>
-      <p className="mt-2 text-red-700">
-        Root tokens should <strong>NEVER</strong> be used in production! They provide unlimited access to all Vault operations.
-        Always use limited tokens with specific policies in production environments.
-      </p>
-    </div>
-  </div>
-</div>
-
-**Recommended Limited Token**
-```hcl
-# Policy: mcp-server-policy
-path "sys/mounts" {
-  capabilities = ["read", "list"]
-}
-
-path "sys/mounts/*" {
-  capabilities = ["create", "update", "delete"]
-}
-
-path "secret/*" {
-  capabilities = ["create", "read", "update", "delete", "list"]
-}
-
-path "pki/*" {
-  capabilities = ["create", "read", "update", "delete", "list"]
-}
-```
-
-Create and use limited token:
-```bash
-# Write policy
-vault policy write mcp-server mcp-policy.hcl
-
-# Create token
-vault token create \
-  -policy=mcp-server \
-  -ttl=720h \
-  -renewable=true \
-  -display-name="mcp-server-prod"
-
-# Use token in k8s secret
-kubectl create secret generic vault-credentials -n kagent \
-  --from-literal=VAULT_ADDR="https://vault.prod.internal:8200" \
-  --from-literal=VAULT_TOKEN="hvs.LIMITED_TOKEN_HERE"
-```
-
-#### Network Security Layers
-
-**Layer 1: Kubernetes Network Policies**
-```yaml
-apiVersion: networking.k8s.io/v1
-kind: NetworkPolicy
-metadata:
-  name: vault-mcp-server-policy
-  namespace: kagent
-spec:
-  podSelector:
-    matchLabels:
-      app: vault-mcp-server
-  policyTypes:
-  - Ingress
-  - Egress
-  ingress:
-  - from:
-    - namespaceSelector:
-        matchLabels:
-          name: kagent
-    ports:
-    - protocol: TCP
-      port: 8084
-  egress:
-  - to:
-    - podSelector: {}
-    ports:
-    - protocol: TCP
-      port: 53  # DNS
-  - to:
-    - ipBlock:
-        cidr: 172.16.10.152/32  # Vault server only
-    ports:
-    - protocol: TCP
-      port: 8200
-```
-
-**Layer 2: TLS Encryption**
-```bash
-# Enable TLS on Vault MCP Server (production)
-CMD ["/app/vault-mcp-server", "streamable-http", \
-     "--transport-port", "8084", \
-     "--transport-host", "0.0.0.0", \
-     "--tls-cert", "/certs/server.crt", \
-     "--tls-key", "/certs/server.key"]
-```
-
-**Layer 3: Vault Audit Logging**
-```bash
-# Enable audit logging on Vault server
-vault audit enable file file_path=/vault/logs/audit.log
-
-# View audit logs
-tail -f /vault/logs/audit.log | jq .
-```
-
-Sample audit log entry:
-```json
-{
-  "time": "2024-01-22T10:30:00.123456Z",
-  "type": "response",
-  "auth": {
-    "client_token": "hmac-sha256:abc123...",
-    "accessor": "hmac-sha256:def456...",
-    "display_name": "mcp-server-prod",
-    "policies": ["default", "mcp-server"]
-  },
-  "request": {
-    "operation": "update",
-    "path": "secret/data/myapp/db"
-  },
-  "response": {
-    "data": {
-      "version": 1
-    }
-  }
-}
-```
-
-## Performance and Scalability
-
-### Benchmarks
-
-**Single Request Latency:**
-```
-Operation              | Cold Start | Warm (Cached)
------------------------|------------|---------------
-list_mounts           | 80-120ms   | 30-50ms
-read_secret           | 100-150ms  | 40-80ms
-write_secret          | 120-180ms  | 50-100ms
-issue_certificate     | 200-400ms  | 150-300ms
-```
-
-**Concurrent Operations:**
-```
-Concurrent Requests | Throughput   | p95 Latency
---------------------|--------------|-------------
-10                  | 95 req/s     | 120ms
-50                  | 380 req/s    | 150ms
-100                 | 520 req/s    | 280ms
-```
-
-### Scaling Strategies
-
-**Horizontal Scaling:**
-```bash
-# Scale MCP server replicas
-kubectl scale deployment vault-mcp-server -n kagent --replicas=3
-
-# All replicas share same Vault connection pool
-# Kubernetes service load-balances requests
-```
-
-**Resource Optimization:**
-```yaml
-resources:
-  requests:
-    memory: "128Mi"  # Base memory
-    cpu: "100m"      # Minimal CPU
-  limits:
-    memory: "512Mi"  # Maximum memory
-    cpu: "500m"      # Burst CPU
-```
-
-**Connection Pooling:**
-
-The Vault Go SDK maintains persistent HTTP connections:
-- First request: Establishes connection (~100ms overhead)
-- Subsequent requests: Reuse connection (~20ms overhead)
-- Connection timeout: 60 seconds
-- Max idle connections: 100
-

-
-## Production Considerations
-
-### Monitoring and Observability
-
-**1. Pod Metrics**
-```bash
-# Install metrics-server if not present
-kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml
-
-# Monitor resource usage
-kubectl top pod -n kagent -l app=vault-mcp-server
-
-# Example output:
-NAME                               CPU(cores)   MEMORY(bytes)
-vault-mcp-server-78855fdf67-abc12  45m          156Mi
-```
-
-**2. Application Logs**
-```bash
-# Stream logs with timestamps
-kubectl logs -f deployment/vault-mcp-server -n kagent --timestamps=true
-
-# Search for errors
-kubectl logs deployment/vault-mcp-server -n kagent | grep -i error
-
-# Export logs for analysis
-kubectl logs deployment/vault-mcp-server -n kagent --since=1h > vault-mcp.log
-```
-
-**3. Health Checks**
-```yaml
-# Already configured in deployment.yaml
-livenessProbe:
-  tcpSocket:
-    port: 8084
-  initialDelaySeconds: 10
-  periodSeconds: 30
-
-readinessProbe:
-  tcpSocket:
-    port: 8084
-  initialDelaySeconds: 5
-  periodSeconds: 10
-```
-
-**4. Prometheus Metrics (Optional)**
-
-Add Prometheus exporter:
-```yaml
-apiVersion: v1
-kind: Service
-metadata:
-  name: vault-mcp-server-metrics
-  namespace: kagent
-  labels:
-    app: vault-mcp-server
-  annotations:
-    prometheus.io/scrape: "true"
-    prometheus.io/port: "9090"
-spec:
-  ports:
-  - port: 9090
-    name: metrics
-  selector:
-    app: vault-mcp-server
-```
-
-### Backup and Disaster Recovery
-
-**1. Vault Data Backup**
-```bash
-# Vault backs up its own data
-# MCP server is stateless - no backup needed
-
-# For Vault server backup (run on Vault server):
-vault operator raft snapshot save backup-$(date +%Y%m%d).snap
-
-# Restore if needed:
-vault operator raft snapshot restore backup-20240122.snap
-```
-
-**2. Configuration Backup**
-```bash
-# Backup Kubernetes manifests
-kubectl get deployment vault-mcp-server -n kagent -o yaml > deployment-backup.yaml
-kubectl get service vault-mcp-server -n kagent -o yaml > service-backup.yaml
-kubectl get secret vault-credentials -n kagent -o yaml > secret-backup.yaml
-kubectl get remotemcpserver vault-mcp-remote -n kagent -o yaml > mcp-backup.yaml
-kubectl get agent vault-secrets-agent -n kagent -o yaml > agent-backup.yaml
-```
-
-**3. Disaster Recovery Procedure**
-```bash
-# 1. Verify Vault is healthy
-vault status
-
-# 2. Redeploy MCP server
-kubectl apply -f k8s/
-
-# 3. Verify connectivity
-kubectl run test-vault --rm -it --image=curlimages/curl --restart=Never -n kagent -- \
-  curl -X POST http://vault-mcp-server:8084/mcp \
-  -d '{"jsonrpc":"2.0","method":"tools/list","id":1}'
-
-# 4. Test with AI assistant
-# Ask: "List all mounts in Vault"
-```
-
-### Troubleshooting Guide
-
-**Problem 1: Pod Not Starting**
-
-Symptoms:
-```bash
-kubectl get pods -n kagent -l app=vault-mcp-server
-# NAME                                READY   STATUS             RESTARTS
-# vault-mcp-server-78855fdf67-abc12   0/1     CrashLoopBackOff   3
-```
-
-Debug:
-```bash
-# Check pod logs
-kubectl logs vault-mcp-server-78855fdf67-abc12 -n kagent
-
-# Check events
-kubectl describe pod vault-mcp-server-78855fdf67-abc12 -n kagent
-
-# Common issues:
-# - Invalid VAULT_ADDR format (missing http://)
-# - Invalid VAULT_TOKEN
-# - Vault server not reachable
-```
-
-Fix:
-```bash
-# Verify secret values
-kubectl get secret vault-credentials -n kagent -o jsonpath='{.data.VAULT_ADDR}' | base64 -d
-kubectl get secret vault-credentials -n kagent -o jsonpath='{.data.VAULT_TOKEN}' | base64 -d
-
-# Test Vault connectivity from cluster
-kubectl run vault-test --rm -it --image=curlimages/curl --restart=Never -n kagent -- \
-  curl -v http://172.16.10.152:8200/v1/sys/health
-```
-
-**Problem 2: MCP Server Not Accessible**
-
-Symptoms:
-```bash
-# kagent can't reach MCP server
-# Error: Connection refused or timeout
-```
-
-Debug:
-```bash
-# Check service endpoints
-kubectl get endpoints vault-mcp-server -n kagent
-
-# Should show pod IPs:
-# NAME               ENDPOINTS           AGE
-# vault-mcp-server   10.244.0.15:8084    5m
-
-# Test from another pod
-kubectl run test --rm -it --image=nicolaka/netshoot --restart=Never -n kagent -- \
-  curl http://vault-mcp-server:8084/mcp
-```
-
-Fix:
-```bash
-# Verify service selector matches pod labels
-kubectl get service vault-mcp-server -n kagent -o yaml | grep selector -A2
-kubectl get pod -n kagent -l app=vault-mcp-server --show-labels
-
-# Restart deployment if needed
-kubectl rollout restart deployment vault-mcp-server -n kagent
-```
-
-**Problem 3: Vault Authentication Failures**
-
-Symptoms:
-```
-Error: permission denied
-Error: invalid token
-```
-
-Debug:
-```bash
-# Check token from pod
-kubectl exec deployment/vault-mcp-server -n kagent -- sh -c \
-  'wget --header="X-Vault-Token: $VAULT_TOKEN" -O- $VAULT_ADDR/v1/sys/auth'
-
-# Check token capabilities on Vault server
-vault token lookup hvs.xVYhjPUczOmmRElkdZotFG11
-vault token capabilities hvs.xVYhjPUczOmmRElkdZotFG11 secret/data/test
-```
-
-Fix:
-```bash
-# Create new token with correct policies
-vault token create -policy=mcp-server -ttl=720h
-
-# Update secret with new token
-NEW_TOKEN="hvs.NEW_TOKEN_HERE"
-kubectl create secret generic vault-credentials -n kagent \
-  --from-literal=VAULT_ADDR="http://172.16.10.152:8200" \
-  --from-literal=VAULT_TOKEN="$NEW_TOKEN" \
-  --dry-run=client -o yaml | kubectl apply -f -
-
-# Restart deployment
-kubectl rollout restart deployment vault-mcp-server -n kagent
-```
-
-## Lessons Learned and Best Practices
-
-### What Worked Well
-
-1. **Using Official HashiCorp Code**
-   - Building from the official vault-mcp-server repository
-   - Ensures compatibility and security updates
-   - Community support and documentation
-
-2. **Multi-Stage Docker Build**
-   - Separate build and runtime stages
-   - Final image only ~20MB (Alpine + binary)
-   - Fast startup and low resource usage
-
-3. **Kubernetes-Native Deployment**
-   - Standard K8s primitives (Deployment, Service, Secret)
-   - Easy to manage with kubectl
-   - Integrates with existing K8s tools (monitoring, logging)
-
-4. **Comprehensive Tool Coverage**
-   - 14 tools cover most common use cases
-   - Mount, KV, and PKI operations
-   - Reduces need for manual Vault CLI commands
-
-5. **Security by Design**
-   - Token stored as K8s Secret
-   - Network policies restrict access
-   - Audit logging captures all operations
-
-### Challenges and Solutions
-
-**Challenge 1: Cross-Platform Builds**
-
-Problem: Makefile detected ARM as "aarch64" (kernel name) instead of "arm64" (Go name)
-
-Solution: Replaced `make build` with direct `go build` command, letting Docker buildx set correct GOARCH
-
-**Challenge 2: Container Network Binding**
-
-Problem: Server bound to 127.0.0.1 (localhost only), not accessible from other pods
-
-Solution: Added `--transport-host 0.0.0.0` flag to bind to all interfaces
-
-**Challenge 3: Deprecated HTTP Command**
-
-Problem: Using `http` command showed deprecation warning
-
-Solution: Switched to `streamable-http` (recommended by HashiCorp)
-
-### Best Practices Summary
-
-✅ **DO:**
-- Use limited Vault tokens (not root!)
-- Enable Vault audit logging
-- Implement network policies
-- Monitor resource usage
-- Backup configurations
-- Use TLS in production
-- Rotate tokens regularly
-- Test in non-production first
-
-❌ **DON'T:**
-- Use root tokens in production
-- Expose secrets in logs
-- Skip token expiration
-- Ignore audit logs
-- Deploy without monitoring
-- Skip network security
-- Hard-code credentials
-- Bypass policies
-
