Implementation Reference

• server.js:2031-2037 (handler)

  The execution handler for the 'get-crd' tool. It runs 'kubectl get crd [name] -o yaml' and returns the stdout as text content.

    const { name } = args;
    const cmd = `kubectl get crd ${name} -o yaml`;
    const { stdout } = await execAsync(cmd);
    return {
      content: [{ type: "text", text: stdout || "CRD not found" }]
    };
  }

• server.js:964-977 (schema)

  The tool schema and registration entry in the tools array, defining the name, description, and input schema (requiring 'name' parameter).

  {
    name: "get-crd",
    description: "Get a custom resource definition",
    inputSchema: {
      type: "object",
      properties: {
        name: { 
          type: "string",
          description: "The name of the CRD"
        }
      },
      required: ["name"]
    }
  },

• server.js:1392-1394 (registration)

  The server request handler for listing tools, which returns the full 'tools' array including the 'get-crd' tool definition.

  server.setRequestHandler(ListToolsRequestSchema, async () => {
    return { tools };
  });
