How to Use the ChurchStamp MCP in OpenAI Agents SDK

Q: Can I manage multiple ChurchStamp campaigns with an OpenAI agent?

Yes. Your agent can use listcampaigns to get all current campaigns and getcampaign to fetch details for a specific one. You can build logic to have your agent report on campaign status or archive old ones.

Q: What happens if the ChurchStamp API is down?

Your agent can handle that gracefully. The checkchurchstampstatus tool lets your agent verify API connectivity before it tries to run other operations, preventing errors.

Build production agents with the OpenAI Agents SDK to automate your ChurchStamp postcard campaigns and contact lists.

Automate Mail Campaigns Safely

Your agent can create and manage entire postcard campaigns. It will use `create_campaign` to start a new mailing, then `list_contacts` to pull the recipient list. You can even have it check on progress with `get_campaign`. Because you're using the OpenAI Agents SDK, every action is validated before it runs. You can set up guardrails to prevent your agent from, say, sending a test campaign to your entire member list by accident. It's production-ready control.

Manage Contacts & Designs in Production

This MCP Server gives your agent direct access to your ChurchStamp contacts and postcard designs. Use `create_contact` to add new members to your mailing list or `list_designs` to see which templates are available before starting a campaign. With the SDK's agent handoff feature, you can have one agent specialize in contact management and another in campaign creation. They'll coordinate tasks, and you get a full trace of their actions in your OpenAI dashboard.

Connect Your OpenAI Agent to this MCP Server

Your agent will auto-discover all 10 ChurchStamp tools the moment you connect. It gets functions to `send_mail` for individual postcards, `list_campaigns` to report on outreach efforts, and even `check_churchstamp_status` to make sure the API is up. Setup is just a few lines of Python. You pass the Vinkius MCP Server endpoint to the `MCPServerStreamableHttp` constructor and add it to your agent. That's it. Your agent is now connected to ChurchStamp.

Setup guide

Set up ChurchStamp 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 ChurchStamp tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about ChurchStamp MCP in OpenAI Agents SDK

It connects your agent to the ChurchStamp API through the Vinkius-managed MCP Server. Your agent discovers tools like `create_campaign` and `list_contacts` automatically, letting you build automations in Python with built-in guardrails for safety.

Yes. Your agent can use `list_campaigns` to get all current campaigns and `get_campaign` to fetch details for a specific one. You can build logic to have your agent report on campaign status or archive old ones.

Not at all. You just need to install the SDK, instantiate the `MCPServerStreamableHttp` class with your Vinkius URL, and pass it to your agent's constructor. The tools are discovered automatically, so there's no manual mapping.

Your agent can handle that gracefully. The `check_churchstamp_status` tool lets your agent verify API connectivity before it tries to run other operations, preventing errors.

Your contact data, including names and addresses, is passed through Vinkius's ephemeral, zero-trust environment to ChurchStamp. The OpenAI SDK provides tracing, so you have a full audit log of which agent accessed what data and when. No data is stored long-term on Vinkius servers.
