Kubernetes MCP Server

Instructions

Implementation Reference

• server.js:1459-1467 (handler)

  The execution handler for the 'list-secrets' tool. It extracts the optional namespace from arguments, constructs a 'kubectl get secrets' command, executes it via execAsync, and returns the stdout as text content or a default message if no output.

  case "list-secrets": {
    const { namespace } = args || {};
    const nsArg = namespace ? `-n ${namespace}` : "";
    const cmd = `kubectl get secrets ${nsArg} -o wide`;
    const { stdout } = await execAsync(cmd);
    return {
      content: [{ type: "text", text: stdout || "No secrets found" }]
    };
  }

• server.js:90-100 (schema)

  The schema definition for the 'list-secrets' tool, including name, description, and input schema specifying an optional 'namespace' string parameter.

  name: "list-secrets",
  description: "List Kubernetes secrets in a namespace",
  inputSchema: {
    type: "object",
    properties: {
      namespace: { 
        type: "string",
        description: "The namespace to list secrets from (optional, defaults to current context namespace)"
      }
    }
  }

• server.js:1392-1394 (registration)

  The request handler for listing tools, which returns the 'tools' array containing the 'list-secrets' tool registration.

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