  The implementation of the 'dist-tag' tool using the MCP server tool registration, handling distribution tag management for npm packages.

  server.tool(
    "dist-tag",
    "Manage distribution tags",
    {
      action: z.enum(["ls", "add", "rm"]).describe("Action to perform"),
      package: z.string().describe("Package name (for add: pkg@version)"),
      tag: z.string().optional().describe("Tag name (required for add/rm)"),
    },
    async ({ action, package: pkg, tag }) => {
      const args = ["dist-tag", action, pkg];
      if (tag && (action === "add" || action === "rm")) args.push(tag);
      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,
        };
      }
    },
  );
