stacktrace-mcp

Simple JS Stacktrace MCP for getting the nearest error location from JavaScript bundle URL and lets an LLM checks if it matches anything in the current codebase.

Designed for non-sourcemap users.

Getting started

  1. Clone the repo
  2. Run pnpm i for install
  3. Run pnpm build for building the server
  4. Add the local mcp server file path to your MCP-supported app (VSCode Copilot, etc): 
    // settings.json
"mcp": {
    "servers": {
    "stacktrace-mcp-server": {
        "type": "stdio",
        "command": "node",
        "args": [
             "<your-path-to>\/stacktrace-mcp\/dist\/mcp_server.cjs"
        ]
    }
    }
}
  5. Make sure the mcp tool is already enabled
  6. Copy your error stack trace to the prompt chat! That's it
