Compatible with every major AI agent and IDE
What is the Google Pub/Sub Subscription MCP Server?
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.
Built-in capabilities (2)
Acknowledge messages to remove them from the Pub/Sub Subscription
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
Why Cursor?
Cursor's Agent mode turns Google Pub/Sub Subscription into an in-editor superpower. Ask Cursor to generate code using live data from Google Pub/Sub Subscription and it fetches, processes, and writes. all in a single agentic loop. 2 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
- —
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
- —
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
- —
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
- —
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

Why teams choose Vinkius for Google Pub/Sub Subscription in Cursor
The Google Pub/Sub Subscription MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 2 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Cursor only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

How Vinkius secures
Google Pub/Sub Subscription for Cursor
Every tool call from Cursor to the Google Pub/Sub Subscription MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Why limit the agent to a single Pub/Sub Subscription?
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.
Why do I need to acknowledge messages?
Pub/Sub uses at-least-once delivery. If you pull a message but don't acknowledge it using its ackId, the message will reappear in the queue after the acknowledgment deadline expires.
Does the agent handle base64 decoding?
Yes! The MCP Engine automatically decodes the data field of every incoming message from base64 into an easily readable UTF-8 string/JSON.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
Server shows as disconnected
Check Settings → Features → MCP and verify the server status. Try clicking the refresh button.
