How to Use the Middesk MCP in OpenAI Agents SDK

Q: How do I connect Middesk to my OpenAI Agents SDK project?

Use the MCPServerStreamableHttp class to point your agent at the server URL. Once you pass it into the Agent constructor, the tools become available for immediate use.

Q: Can OpenAI Agents SDK use Middesk to verify tax registrations?

Instant business verification for OpenAI Agents SDK

Stop manual data entry for merchant onboarding by using `autocomplete_identity` to pull legal business details directly from official registries. Your agent grabs the core identity data, ensuring your compliance pipeline stays clean without human intervention. This MCP Server handles the handshake, letting your agent focus on risk assessment rather than state-level data scraping. It's built for production systems where you need reliable, verified entity info immediately.

Automated tax and document tracking

Use `list_tax_registrations` to pull filing statuses for any entity your agent is vetting. It connects your compliance logic to current tax records, giving your agent the full picture required for KYC/KYB decisions. Once the agent identifies a entity, call `get_document` to fetch specific filings. This lets your agent perform automated deep-dives into business history, flagging inconsistencies before they hit your desk.

Production-grade entity management

Initialize new verification workflows with `create_business` directly from your agent's decision loop. This keeps your onboarding flow moving, turning a complex multi-step process into a single, automated server call. When you need to audit existing records, `list_businesses` provides the full history. It's a straightforward way to keep your agent's knowledge base synced with the actual legal status of your merchants.

Setup guide

Set up Middesk 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 Middesk tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Middesk MCP in OpenAI Agents SDK

Use the `MCPServerStreamableHttp` class to point your agent at the server URL. Once you pass it into the `Agent` constructor, the tools become available for immediate use.

Yes. Your agent can call `list_tax_registrations` to pull current filing data. It's a direct way to confirm a business is in good standing.

The server provides raw data that your agent's guardrails can validate immediately. Since the tool responses are structured, your existing validation logic will catch any unexpected fields.

Vinkius manages the connection, but you should still implement standard error handling in your agent code. This ensures your workflow doesn't stall if a registry is temporarily busy.

The data is ephemeral and transit-only. Your agent only sees the specific records you request, and we don't store your query history or entity results.
