Google Pub/Sub Topic MCP Connector for Claude

This MCP does exactly one thing: it publishes messages to a single Google Pub/Sub Topic. That's its only function, and nothing else. Incredible for giving your AI the power to trigger cloud events.

More Details Connect to Claude

This server strips away dangerous global GCP permissions. It gives your AI agent one surgical superpower: the ability to publish messages and trigger events on one specific Pub/Sub Topic.

By strictly scoping access, your AI can safely fan out notifications, trigger downstream workers, and emit system alerts without ever compromising the rest of your messaging infrastructure.

The Superpowers

  • Absolute Containment: The agent is locked to a single topic. It cannot publish to other topics or alter topic configurations.
  • Native Pub/Sub Integration: Send payloads with advanced message attributes.
  • Plug & Play Event Trigger: Instantly gives your agent the ability to act as an event producer in your distributed system architecture.

Publish a message to the configured Google Cloud Pub/Sub Topic

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

Publish an event indicating that the user sign-up was verified.

Done! I've published the message to the topic. The generated Message ID is '3910398201'.

Send the invoice payload to the topic with the attribute 'type=invoice_ready'.

The payload was successfully published. The attribute 'type: invoice_ready' was attached for downstream filtering.

Trigger the background data export via Pub/Sub.

Message sent. The workers subscribed to the topic will now begin the background export process.

To enforce zero-trust architecture. An autonomous AI agent should not have the ability to publish events to arbitrary critical infrastructure topics (e.g., billing alerts or user deletion events).
