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

Google Pub/Sub Subscription for LlamaIndex
Every tool call from LlamaIndex 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.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query Google Pub/Sub Subscription tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
