  The "uninstall" tool is registered and implemented in src/index.ts. It calls the 'run' helper function with the appropriate 'npm uninstall' arguments.

  // ── npm uninstall ──
  server.tool(
    "uninstall",
    "Remove packages from a project",
    {
      path: z.string().describe("Absolute path to the package directory"),
      packages: z.array(z.string()).describe("Package names to uninstall"),
      global: z.boolean().optional().describe("Uninstall from global"),
    },
    async ({ path, packages, global: isGlobal }) => {
      const args = ["uninstall", ...packages];
      if (isGlobal) args.push("-g");
      try {
        const { stdout, stderr } = await run(args, path);
        return { content: [{ type: "text", text: stdout + stderr }] };
      } catch (e: any) {
        return {
          content: [{ type: "text", text: `Error: ${e.stderr || e.message}` }],
          isError: true,
        };
      }
    },
  );
