Triage Agent

MCP server that guides an AI agent through stack trace triage — from raw error to the commit and PR that introduced it.

How it works

Three tools, called in sequence by the agent:

Tool	Input	Output
blame_stack_trace	raw stack trace	instructions to identify the source file and line
submit_trace_location	file path + line range	git blame command to run + instructions to gather commit context
submit_git_context	commit message, PR info, comments	structured triage result as JSON

Example

Use mcp__triage-agent-mcp__blame_stack_trace to analyze this error:

Uncaught TypeError: Cannot read properties of null (reading 'useContext')
  at e.useContext (_virtual_mf___mfe_internal__remote__loadShare__react__loadShare__.mjs)
  at app-xaIRccHv.js:3:17698

The agent calls all three tools in sequence and returns the commit message, PR, and reviewer comments linked to the fault.

Usage

Add to your MCP client config (e.g. Claude Desktop claude_desktop_config.json):

{
  "mcpServers": {
    "triage-agent-mcp": {
      "command": "node",
      "args": ["/path/to/triage-agent-mcp/dist/index.js"]
    }
  }
}

Development

npm install
npm test         # tsc type-check + smoke test
npm run build    # tsc → dist/
