Connect Google Pub/Sub Topic to ChatGPT, Claude and Gemini

Set it up once and it works in ChatGPT, Claude, Cursor, and any other client you love. It all runs safely in the background, so you can relax and focus on what really matters. Trigger cloud events and system alerts directly from your AI client.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Curated set · 1 capability

We ship only the actions that matter.

Capability set01 / 01

01

1 capability in this set.

Part of 1 available through Google Pub/Sub Topic.

  1. 01

    Publish message

    Sends a message payload to your configured Google Cloud Pub/Sub Topic. You can include specific attributes to help downstream services filter the incoming data.

Real work

What teams actually run

01

Automated User Workflows

The AI triggers a notification topic once a user verification process is complete.

02

System Alerting

Your agent emits a message to a specific topic when it detects an anomaly in your data.

03

Background Task Triggering

You tell your AI to start a heavy data export, and it sends the command via Pub/Sub.

04

Microservices Communication

The AI acts as a bridge to signal downstream workers that a specific event has occurred.

Automate a task

Put Google Pub/Sub Topic to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Google Pub/Sub Topic works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Google Pub/Sub Topic to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 1 capability arrives ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Google Pub/Sub Topic, so you can see the experience inside your AI.

It does not authenticate your account with Google Pub/Sub Topic. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for

Built for the work Google Pub/Sub Topic owners hand off.

This is built for engineers managing event-driven cloud architectures who want to add AI agency to their workflows.

  • 01

    Cloud Engineers

    They use the MCP to bridge AI reasoning with existing GCP messaging pipelines.

  • 02

    Backend Developers

    They hand off event triggering tasks to the AI to automate system notifications.

  • 03

    DevOps Specialists

    They use it to trigger automated workflows or alerts through a controlled interface.

FAQ

Questions Google Pub/Sub Topic owners ask.

  • 01

    Can this MCP publish to any topic in my GCP project?

    No. This MCP is designed to be scoped to one specific topic to ensure security and containment.

  • 02

    What AI clients can I use with this?

    You can use any MCP-compatible client, including Claude, Cursor, Windsurf, and VS Code.

  • 03

    How does this handle security?

    It avoids using broad, global GCP permissions. Instead, it uses scoped access limited to the single topic you configure.

  • 04

    Can I add metadata to my messages?

    Yes. You can include advanced message attributes with your payloads to help with downstream filtering.

  • 05

    Do I need to host the MCP myself?

    No. Vinkius hosts and manages the MCP for you, so it is ready to use immediately after connection.

  • 06

    Why limit the agent to a single Pub/Sub Topic?

    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).

  • 07

    Do I need to base64-encode my messages manually?

    No. Provide plain text or JSON strings directly to the capability. The engine will automatically convert your payload to base64 as required by the Google Cloud Pub/Sub REST API.

  • 08

    Can the agent receive messages with this capability?

    No. This capability only has publish_message capabilities to enforce unidirectional isolation. If the agent needs to receive messages, it must use the Google Pub/Sub Subscription MCP.
