Implementation Reference

• src/index.ts:892-906 (handler)

  The tool 'doctor' is defined and registered using server.tool, and its handler logic executes `npm doctor` using the `run` helper function.

  // ── npm doctor ──
  server.tool(
    "doctor",
    "Run diagnostics to check npm environment health",
    {},
    async () => {
      try {
        const { stdout, stderr } = await run(["doctor"]);
        return { content: [{ type: "text", text: stdout + stderr }] };
      } catch (e: any) {
        // doctor may exit non-zero if checks fail
        return { content: [{ type: "text", text: e.stdout || e.stderr || e.message }] };
      }
    },
  );
