Implementation Reference

• src/index.ts:353-373 (handler)

  The tool 'outdated' is registered and implemented directly in src/index.ts, using the 'run' helper to execute 'npm outdated' with appropriate arguments.

  server.tool(
    "outdated",
    "Check for outdated packages in a project",
    {
      path: z.string().describe("Absolute path to the package directory"),
      global: z.boolean().optional().describe("Check global packages"),
      long: z.boolean().optional().describe("Show extended information"),
    },
    async ({ path, global: isGlobal, long }) => {
      const args = ["outdated", "--json"];
      if (isGlobal) args.push("-g");
      if (long) args.push("--long");
      try {
        const { stdout } = await run(args, path);
        return { content: [{ type: "text", text: stdout || "{}" }] };
      } catch (e: any) {
        // npm outdated exits non-zero when outdated packages found
        return { content: [{ type: "text", text: e.stdout || e.stderr || e.message }] };
      }
    },
  );
