The stacktrace-mcp project provides a simple JavaScript Stacktrace MCP server that helps find the nearest error location from JavaScript bundles and checks for matches in the codebase without needing a sourcemap. It is useful for integrating with MCP-supported applications like VSCode Copilot.

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
