Implementation Reference

• src/index.ts:216-229 (handler)

  The handler function for the 'owner' tool, which constructs the npm command arguments and executes them.

  async ({ action, package: pkg, user, otp }) => {
    const args = ["owner", action, pkg];
    if (user && (action === "add" || action === "rm")) args.push(user);
    if (otp) args.push("--otp", otp);
    try {
      const { stdout } = await run(args);
      return { content: [{ type: "text", text: stdout }] };
    } catch (e: any) {
      return {
        content: [{ type: "text", text: `Error: ${e.stderr || e.message}` }],
        isError: true,
      };
    }
  },

• src/index.ts:210-215 (schema)

  Zod schema definition for the 'owner' tool arguments.

  {
    action: z.enum(["ls", "add", "rm"]).describe("Action to perform"),
    package: z.string().describe("Package name"),
    user: z.string().optional().describe("Username (required for add/rm)"),
    otp: z.string().optional().describe("One-time password for 2FA"),
  },

• src/index.ts:207-230 (registration)

  Full registration of the 'owner' tool using server.tool.

  server.tool(
    "owner",
    "Manage package owners",
    {
      action: z.enum(["ls", "add", "rm"]).describe("Action to perform"),
      package: z.string().describe("Package name"),
      user: z.string().optional().describe("Username (required for add/rm)"),
      otp: z.string().optional().describe("One-time password for 2FA"),
    },
    async ({ action, package: pkg, user, otp }) => {
      const args = ["owner", action, pkg];
      if (user && (action === "add" || action === "rm")) args.push(user);
      if (otp) args.push("--otp", otp);
      try {
        const { stdout } = await run(args);
        return { content: [{ type: "text", text: stdout }] };
      } catch (e: any) {
        return {
          content: [{ type: "text", text: `Error: ${e.stderr || e.message}` }],
          isError: true,
        };
      }
