Connect your AI to Google Pub/Sub to turn chat commands into cloud events. Once connected, your agent can trigger any process listening to your specific topic.

Short answer

How can I use my AI to start cloud processes?

Your AI uses the publish_message tool to drop a payload into a designated Google Pub/Sub topic. This message acts as a signal for your cloud infrastructure to start running heavy data tasks. You'll see how the handoff works below.

Where signals land.

The outcomes of a trigger.

The AI acts as the trigger for your backend services.

EVENT

Instant cloud triggers

The AI sends a message to your topic. This immediately alerts your cloud functions or workers to start their work.

DATA

Payload delivery

Your agent includes specific data in the message. This ensures your backend receives the exact parameters it needs to run.

LOGS

Execution tracking

Once the message is sent, your cloud logs will show the incoming event. You can monitor the task progress in your Google Cloud console.

HUMAN

Manual oversight

The AI only sends the signal. You still manage the actual cloud infrastructure and the logic that processes the messages.

The workflow

What your AI does when a command arrives.

The AI handles the communication layer between your chat and your cloud environment.

  1. Parse the intent

    Your agent looks at your request to figure out what data needs to be sent to the cloud.

    publish_message

  2. Format the payload

    The AI structures your instructions into a valid message format for the topic.

    publish_message

  3. Send the signal

    The agent pushes the message directly to your specified Google Pub/Sub topic.

    publish_message

  4. Confirm delivery

    The AI verifies the message was successfully published so you know the trigger worked.

FAQ

How the trigger behaves

  • 01

    Can the AI create new Pub/Sub topics?

    No. The AI can only publish messages to topics that already exist in your Google Cloud project.

  • 02

    Will the AI delete my existing messages or topics?

    No. This MCP only has the ability to publish messages. It cannot delete, modify, or manage your cloud resources.

  • 03

    Does the AI know if my cloud function actually finished the task?

    No. The AI only knows that the message was successfully delivered to the topic. It cannot see the results of the downstream process.

  • 04

    Can I send complex JSON objects?

    Yes. You can tell your agent to include specific JSON payloads in the message it publishes.

  • 05

    Do I need to provide my Google Cloud keys?

    You provide them once during setup. Vinkius manages the connection securely so you don't have to paste keys into every chat.
