Perplexity

Fetch messages with OpenAI Agents SDK

Your agent pulls raw data directly from your queue using the `pull_messages` tool. This bypasses complex middleware and gives your logic direct access to the stream. Keep your agent logic clean by treating these messages as the primary source of truth. The SDK handles the connection while you define how the agent reacts to incoming payloads.

Manage message lifecycle in OpenAI Agents SDK

Once your agent completes its task, use `acknowledge_messages` to commit the transaction. This removes the message from the subscription and prevents redundant processing cycles. Failing to call this tool triggers redelivery, which clutters your logs. Explicit control ensures your agent only handles each piece of data exactly one time.

Secure MCP Server integration

This MCP Server relies on standard Google Cloud IAM roles to verify your agent's identity. Your environment remains locked down because you only grant the specific permissions needed for message retrieval. Connect your OpenAI Agents SDK instance by pointing it at the Vinkius endpoint. You get a direct line to your data without opening your infrastructure to external threats.

Setup guide

Set up Google Pub/Sub Subscription MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all Google Pub/Sub Subscription tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Google Pub/Sub Subscription tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Google Pub/Sub Subscription tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="Google Pub/Sub Subscription Agent",
            instructions="You have access to Google Pub/Sub Subscription tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Google Pub/Sub Subscription MCP in OpenAI Agents SDK

You initialize an MCPServerStreamableHttp instance with the Vinkius URL and pass it to your agent constructor. The SDK automatically detects the available tools.

Yes, provided you manage your acknowledgment flow correctly. Your agent must call `acknowledge_messages` promptly to clear the queue and maintain system throughput.

The server supports multiple concurrent connections. You can scale your agent instances horizontally to pull and process messages in parallel.

The message remains unacknowledged in the queue. It will reappear for another agent instance to process once the visibility timeout expires.

Yes. The server only touches message bodies and ack IDs. All traffic is encrypted in transit and confined to your authenticated GCP project boundaries.
