- trace_method_calls: method call tracing

## Config

### Add to Cursor / Claude Code

macOS: `~/.cursor/mcp.json`
Windows: `C:\Users\{username}\.cursor\mcp.json`

```json
{
  "mcpServers": {
    "arthas": {
      "command": "uv",
      "args": ["--directory", "F:\\path\\to\\arthas_mcp_server", "run", "python", "main.py"],
      "env": { "ARTHAS_URL": "http://localhost:8563" }
    }
  }
}
```

### Start Arthas

There are multiple deployment methods: either attach mode or agent mode. Both approaches ultimately result in listening for HTTP requests (Arthas commands) on port 8563.
