Google Pub/Sub Subscription MCP Connector for Claude

A+

This MCP does exactly one thing: it pulls and acknowledges messages from a single Google Pub/Sub Subscription. That's its only function, and nothing else. Incredible for building secure AI workers.

More Details Connect to Claude

This server strips away dangerous global GCP permissions. It gives your AI agent one surgical superpower: the ability to pull tasks and acknowledge completion on one specific Pub/Sub Subscription.

By strictly scoping access, your AI can safely operate as a highly scalable background worker, processing tasks one by one without ever accessing other subscriptions.

The Superpowers

  • Absolute Containment: The agent is locked to a single subscription. It cannot peek into other workloads or purge queues.
  • Native Pub/Sub Integration: Uses standard polling and acknowledgment mechanisms to ensure tasks are processed reliably.
  • Plug & Play Worker: Instantly turns your AI into an asynchronous background worker capable of chewing through millions of queued tasks.

2 tools expose this connector's capabilities to your AI agent.

pull_messages

You MUST acknowledge the messages using their ackIds after you process them, otherwise they will be redelivered. Pull messages from the configured Google Cloud Pub/Sub Subscription

acknowledge_messages

Acknowledge messages to remove them from the Pub/Sub Subscription

See how to talk to your AI agent using Google Pub/Sub Subscription.

Pull the latest 5 messages from the subscription.

I retrieved 2 messages. The first message contains a JSON payload instructing a database backup. Here are their ackIds for when we finish processing.

Process the first message payload and write a summary.

The message data contains an alert about high CPU usage. I have created the summary report as requested.

Acknowledge the messages using these IDs: ["ack123", "ack456"].

Successfully acknowledged 2 messages. They will no longer appear in the queue.

To enforce zero-trust security. An autonomous AI agent pulling its worker tasks should not have access to read messages from unrelated subscriptions, such as system audit logs or financial events.
