+
+## Ready for Deployment
+
+### 1. MCP Server → npm + MCP Registry
+
+#### Publishing to npm
+```bash
+# Ensure you're logged in
+npm whoami
+
+# Publish to npm
+npm publish --access public
+
+# Verify published package
+npx -y @ewalid/rosetta-mcp
+```
+
+#### Submitting to MCP Registry
+1. Fork: https://github.com/modelcontextprotocol/servers
+2. Add `src/rosetta/server.json` with metadata
+3. Add documentation in `src/rosetta/README.md`
+4. Create pull request
+5. Wait for review and approval
+
+#### User Installation (After Publishing)
+```json
+// ~/.config/claude-desktop/config.json
+{
+  "mcpServers": {
+    "rosetta": {
+      "command": "npx",
+      "args": ["-y", "@ewalid/rosetta-mcp"],
+      "env": {
+        "ANTHROPIC_API_KEY": "sk-ant-your-key-here"
+      }
+    }
+  }
+}
+```
+
+### 2. HTTP API → Production Deployment
+
+#### Environment Configuration
+```bash
+# Required environment variables
+export ENVIRONMENT=production
+export ANTHROPIC_API_KEY=sk-ant-your-key-here
+export RECAPTCHA_SECRET_KEY=your_recaptcha_secret
+export RECAPTCHA_SITE_KEY=your_recaptcha_site
+export FRONTEND_URL=https://your-frontend.com
+export CORS_ALLOW_ALL=false  # NEVER true in production!
+
+# Optional
+export MAX_FILE_SIZE=52428800  # 50MB
+export MAX_CONTEXT_LENGTH=1000
+```
+
+#### Deployment Command
+```bash
+# Install dependencies
+uv sync
+
+# Run in production
+uv run uvicorn rosetta.api:app \
+  --host 0.0.0.0 \
+  --port 8000 \
+  --workers 4 \
+  --log-level info
+```
+
+#### Docker Deployment (Recommended)
+```dockerfile
+FROM python:3.11-slim
+
+WORKDIR /app
+COPY . .
+
+RUN pip install uv && uv sync
+
+EXPOSE 8000
+
+CMD ["uv", "run", "uvicorn", "rosetta.api:app", "--host", "0.0.0.0", "--port", "8000"]
+```
+
+```bash
+docker build -t rosetta-api .
+docker run -p 8000:8000 \
+  -e ENVIRONMENT=production \
+  -e ANTHROPIC_API_KEY=$ANTHROPIC_API_KEY \
+  -e RECAPTCHA_SECRET_KEY=$RECAPTCHA_SECRET_KEY \
+  rosetta-api
+```
+
+---
+
+## Post-Deployment Verification
+
+### 1. MCP Server Verification
+```bash
+# Test the published package
+npx -y @ewalid/rosetta-mcp
+
+# In Claude Desktop, try:
+"Count cells in ~/Downloads/report.xlsx"
+"Translate ~/Documents/data.xlsx to French"
+```
+
+### 2. HTTP API Verification
+```bash
+# Health check
+curl https://your-api.com/health
+
+# Test translation endpoint
+curl -X POST https://your-api.com/estimate \
+  -F "file=@test.xlsx" \
+  -F "recaptcha_token=valid_token"
+
+# Run comprehensive security tests against production
+ROSETTA_API_URL=https://your-api.com uv run python test_comprehensive_security.py
+```
+
+---
+
+## Monitoring & Maintenance
+
+### Recommended Monitoring
+
+1. **Error Tracking**: Set up Sentry or similar
+   ```bash
+   export SENTRY_DSN=your_sentry_dsn
+   ```
+
+2. **Request Logging**: Monitor for suspicious patterns
+   - High rate of invalid file uploads
+   - Prompt injection attempts
+   - CORS violations
+   - reCAPTCHA failures
+
+3. **Performance Monitoring**
+   - API response times
+   - Translation success rate
+   - Error rates by endpoint
+
+4. **Security Alerts**
+   - Rate limit violations
+   - File validation failures
+   - Authentication failures
+
+### Logs to Monitor
+```bash
+# Application logs
+tail -f /var/log/rosetta/app.log
+
+# Security events
+grep "ERROR" /var/log/rosetta/app.log | grep -E "(validation|rate|CORS|reCAPTCHA)"
+
+# Performance metrics
+grep "POST /translate" /var/log/rosetta/app.log | awk '{print $4}' | sort -n
+```

+✅ Validates file magic bytes (prevents spoofing)
+✅ Resolves symlinks (prevents file system attacks)
+✅ Enforces 50MB file size limit
+✅ Protects against prompt injection (16 patterns)
+✅ Prevents Unicode/control character attacks
+✅ Never overwrites existing files
