Execute remote business logic

When you need your agent to run heavy processing tasks or access external services, the `gcf_invoke_function` tool makes it happen. This lets your AI client execute secure serverless compute steps that aren't part of the main chat flow. It’s perfect for calling out business logic—think image resizing or complex data transformation—without having to manage infrastructure yourself. Your agent just calls the function and gets a clean result back.

Manage multi-step workflows

Your agent can use this MCP to perform several distinct steps in sequence, chaining together different external services. This means you don't write monolithic code; instead, you define microservices that your agents call out. This is key for building truly robust systems. If the first step works, the second one can execute reliably because it’s calling a specific, isolated function endpoint.

Integrate specialized computation

Need to run complex calculations that hit rate limits or are too long for a single API call? Use this MCP to offload the work. Your agent passes the necessary parameters and waits for the result. It keeps your main conversational flow clean while ensuring heavy lifting happens in a controlled, external environment. The entire process is managed securely by Vinkius.

Setup guide

Set up Google Cloud Functions 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 Cloud Functions tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Google Cloud Functions 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 Cloud Functions 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 Cloud Functions Agent",
            instructions="You have access to Google Cloud Functions tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Google Cloud Functions MCP in OpenAI Agents SDK

The OpenAI Agents SDK auto-discovers this MCP and treats it like any other tool. You simply pass the server to your Agent constructor, and the guardrails handle all validation before calling Google Cloud Functions.

Use it when an action requires guaranteed execution outside of the agent's immediate context. For instance, if a user uploads a file and needs that file processed by a backend worker, this MCP handles the call.

While the core invocation is designed for result retrieval, you can wrap the tool calls in async contexts. This allows your agent to manage complex workflows that treat external service results as streamable outputs.

No. The MCP handles connection management and optimization. You get native token optimization built in, which cuts down on wasted tokens when your agent calls the function.

The primary data type handled is structured input parameters (JSON) passed to the remote business logic. The resulting output is also typically a JSON payload containing the computation result, ensuring predictable data flow.
