Direct payment execution in OpenAI Agents SDK

Trigger outgoing payouts directly from your agent logic using `modulr_create_payment`. This bypasses manual banking portals and lets your code handle movement of funds based on real-time triggers. Your agent handles the payload and the server signs it with HMAC-SHA256. You get production-grade security without building a custom signing layer.

Native ledger management for OpenAI Agents SDK

Provision accounts instantly using `modulr_create_account` to segment liquidity by customer or entity. Your agent maintains control over the financial structure of your application. Audit your progress by calling `modulr_get_accounts` or `modulr_list_payments`. You see the exact state of your capital at any moment, ensuring your agent logic matches the bank records.

Automated recipient onboarding via OpenAI Agents SDK

Map external entities to your system using `modulr_create_beneficiary` to prepare for fast, automated disbursements. This ensures your agent has the right destination data before it attempts a transfer. Verify your customer entities with `modulr_get_customers` to keep your records clean. Your agent acts on validated data, reducing the risk of failed payments due to bad account details.

Setup guide

Set up Modulr 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 Modulr tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Modulr MCP in OpenAI Agents SDK

You connect the server via the MCPServerStreamableHttp class. Once added to your agent constructor, the tools are auto-discovered and ready for your code to invoke immediately.

Yes. You can queue thousands of transactions using the server tools. The system is built to handle the throughput required for active marketplace payout flows.

The server implements mandatory HMAC-SHA256 signing for all requests. Your agent only communicates over an encrypted channel, keeping your financial keys isolated.

Use `modulr_get_transactions` or `modulr_list_payments`. These tools return the exact status of your outbound payments, allowing your agent to react to settlement updates.

The server touches only the payment metadata and account identifiers required for API operations. No PII is stored locally, and all data transit is strictly ephemeral during your agent's execution.
