Implementation Reference

• src/index.ts:257-278 (handler)

  The registration and handler implementation for the "pack" tool, which creates a tarball of an npm package.

  server.tool(
    "pack",
    "Create a tarball from a package (preview what would be published)",
    {
      path: z.string().describe("Absolute path to the package directory"),
      dryRun: z.boolean().optional().describe("List files without creating tarball"),
    },
    async ({ path, dryRun }) => {
      const args = ["pack"];
      if (dryRun) args.push("--dry-run");
      args.push("--json");
      try {
        const { stdout } = await run(args, path);
        return { content: [{ type: "text", text: stdout }] };
      } catch (e: any) {
        return {
          content: [{ type: "text", text: `Error: ${e.stderr || e.message}` }],
          isError: true,
        };
      }
    },
  );
