Implementation Reference

• src/index.ts:302-322 (handler)

  The 'init' tool is registered and implemented directly in src/index.ts. It calls the 'run' helper function with the 'init' command to initialize a package.json file.

  server.tool(
    "init",
    "Initialize a new package.json",
    {
      path: z.string().describe("Absolute path to the directory"),
      scope: z.string().optional().describe("Scope for the package (e.g. @myorg)"),
    },
    async ({ path, scope }) => {
      const args = ["init", "-y"];
      if (scope) args.push("--scope", scope);
      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,
        };
      }
    },
  );
