 # Changelog
 
+## [0.2.0] - 2026-03-20
+
+### Added
+- MCP server for AI-assisted thread dump analysis (Claude, Copilot, Cursor, etc.)
+- Five MCP tools: `analyze_thread_dump`, `detect_deadlocks`, `get_hot_methods`, `get_thread_summary`, `find_threads_by_method`
+- Stdio and HTTP transport modes with optional Bearer token authentication
+- `findThreadsByMethod()` core utility — search threads by method name with substring or regex matching, returns state breakdown and stack depth info
+- VS Code settings for MCP transport, port, and auth configuration
+

 - No data is sent to any remote server or third-party service.
 - The extension does not use telemetry, analytics, or crash reporting.
 
+## MCP Server
+
+The built-in MCP server runs locally on your machine. When using stdio transport (the default), communication stays within your local process. When using HTTP transport, the server listens only on `localhost` at the port you configure. Token authentication is available for HTTP mode but disabled by default.
+
+Thread dump content is passed directly to the MCP tools in-memory — nothing is logged, cached, or written to disk by the server.
+
 ## Network Access
 
-The only external network request is loading **Chart.js** from `cdn.jsdelivr.net` for rendering pie charts in the dashboard webview. No user data is included in this request.
+This extension makes no external network requests. Chart.js is bundled locally.

+## MCP Server
+
+The extension includes an MCP server that lets AI assistants analyze thread dumps directly. It works with any MCP-compatible client — Claude Code, Claude Desktop, GitHub Copilot Chat, Cursor, etc.
+
+### Available tools
+
+| Tool | What it does |
+|------|-------------|
+| `analyze_thread_dump` | Full analysis: thread states, hot methods, and deadlock detection |
+| `detect_deadlocks` | Focused deadlock cycle detection with lock chain details |
+| `get_hot_methods` | Most frequently occurring methods across all stack traces |
+| `get_thread_summary` | Quick overview: thread count, state breakdown, deadlock count |
+| `find_threads_by_method` | Find threads running a specific method, with state and lock info |
+
+### Standalone (stdio)
+
+Point your MCP client at the server:
+
+```bash
+node out/src/mcp/server.js
+```
+
+For Claude Code, add to your `.mcp.json`:
+
+```json
+{
+  "mcpServers": {
+    "fast-java-thread": {
+      "command": "node",
+      "args": ["path/to/FastJavaThread/out/src/mcp/server.js"]
+    }
+  }
+}
+```
+
+### HTTP mode
+
+For network access (e.g. from a Tauri app), run with HTTP transport:
+
+```bash
+node out/src/mcp/server.js --transport http --port 3100 --auth-token mytoken
+```
+
+### VS Code settings
+
+| Setting | Default | Description |
+|---------|---------|-------------|
+| `fastJavaThread.mcp.transport` | `stdio` | Transport mode: `stdio` or `http` |
+| `fastJavaThread.mcp.port` | `3100` | Port for HTTP transport |
+| `fastJavaThread.mcp.auth.enabled` | `false` | Enable Bearer token auth (HTTP only) |
+| `fastJavaThread.mcp.auth.token` | `""` | Bearer token value |
+
