How to Use the Gmail MCP in OpenAI Agents SDK

Q: How does OpenAI Agents SDK handle rate limits during large Gmail searches?

The SDK manages backoff when your agent calls listgmailthreads repeatedly. If you hit Google API limits, the OpenAI Agents SDK pauses execution until the window resets.

Q: Does this setup support reading multi-threaded Gmail conversations?

Yes, the agent calls getthreaddetails to pull the full history of a conversation. This lets your OpenAI Agents SDK agent understand context before replying.

Run multi-agent Gmail workflows with OpenAI Agents SDK using safe, auto-discovered MCP tools and built-in guardrails.

Perplexity

Query your inbox using the Gmail MCP Server.

The `list_gmail_messages` tool connects your OpenAI Agents SDK agent directly to your inbox to run search queries. Your agent calls `get_message_content` to read the body of those emails without pulling down unnecessary clutter. Running this inside the OpenAI Agents SDK means you can chain these calls. An agent first runs `find_emails_from_sender` to isolate messages, then hands off the clean text to a specialized drafting agent.

Label threads with OpenAI Agents SDK guardrails.

The `modify_message_labels` tool applies system or custom labels to organize your inbox dynamically. Your agent uses `list_mailbox_labels` to check available folders before making changes, preventing messy tag creation. When running these write actions, the OpenAI Agents SDK validates the proposed label changes before executing them. This safety layer stops agents from running wild on your live threads.

Safe trash management for OpenAI Agents SDK.

The `trash_gmail_message` tool moves unwanted or processed emails directly to your Gmail trash. If an agent makes a mistake during a bulk run, you call `untrash_gmail_message` to restore the thread instantly. By using the OpenAI Agents SDK dashboard, you trace every trash and untrash action to audit exactly why your agent decided to archive a thread. This gives you complete visibility into automated cleanup runs.

Setup guide

Set up Gmail 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 Gmail tools at runtime.
3

Create your Agent

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

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Gmail 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="Gmail Agent",
            instructions="You have access to Gmail tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Gmail MCP in OpenAI Agents SDK

You pass your single Vinkius endpoint token to the OpenAI Agents SDK HTTP client wrapper. Vinkius hosts the Gmail MCP Server and handles the underlying OAuth handshake so your Python agent never touches raw Gmail credentials.

Yes, you define allowed tools directly in the OpenAI Agents SDK agent constructor. For example, you can expose `list_unread_emails` while withholding `trash_gmail_message` to enforce a read-only setup.

The SDK manages backoff when your agent calls `list_gmail_threads` repeatedly. If you hit Google API limits, the OpenAI Agents SDK pauses execution until the window resets.

Yes, the agent calls `get_thread_details` to pull the full history of a conversation. This lets your OpenAI Agents SDK agent understand context before replying.

Your email bodies and mailbox profile data pass through an ephemeral V8 sandbox via our MCP runtime. Vinkius never stores your Gmail messages, keeping all text strictly in-memory during execution.
