Implementation Reference

• src/index.ts:909-929 (handler)

  The "cache" tool implementation, which executes npm cache commands using the `run` helper function.

  server.tool(
    "cache",
    "Manage the npm cache",
    {
      action: z.enum(["clean", "verify", "ls"]).describe("Action: clean (clear cache), verify (check integrity), ls (list contents)"),
      force: z.boolean().optional().describe("Force clean (required for clean action)"),
    },
    async ({ action, force }) => {
      const args = ["cache", action];
      if (action === "clean" && force) args.push("--force");
      try {
        const { stdout, stderr } = await run(args);
        return { content: [{ type: "text", text: stdout + stderr || "Done" }] };
      } catch (e: any) {
        return {
          content: [{ type: "text", text: `Error: ${e.stderr || e.message}` }],
          isError: true,
        };
      }
    },
  );
