Safe Asaas MCP Server Execution

Building a finance bot requires strict boundaries. The OpenAI Agents SDK applies built-in guardrails before executing any financial operation through this MCP Server. When your agent tries to run `create_payment` or `create_customer`, the framework validates the parameters against your predefined safety constraints. You'll get full tracing in the OpenAI dashboard for every API call made to the Brazilian payment gateway.

Multi-Agent Financial Workflows

Single agents struggle with complex accounting logic. Handing off tasks between specialized routines solves this problem entirely. You might have one agent reading the `get_balance` and `list_transfers` tools to audit the daily ledger. If it finds a discrepancy, it'll transfer control to a billing agent that uses `list_subscriptions` to identify missing recurring charges.

Zero-Config Tool Discovery

Writing boilerplate code for an MCP integration wastes time. Passing the server endpoint directly to the Agent constructor handles everything automatically. The framework reads the schema and exposes `list_payments` and `get_account_check` to your model immediately. Setting `cacheToolsList=True` drops the initialization latency, letting your system scale efficiently.

Setup guide

Set up Asaas 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 Asaas tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Asaas MCP in OpenAI Agents SDK

Install the package via pip install openai-agents. Initialize the connection using MCPServerStreamableHttp with your Vinkius endpoint URL. Pass it into the mcp_servers list when setting up your agent.

Yes, the server provides full write access. Your agent can call `create_payment` and manage recurring billing cycles directly. Safety guardrails will check the inputs before committing the transaction.

Direct REST integration means writing custom parsing and error handling for every endpoint. The standard gives your agent automatic access to all tools like `list_customers` without manual mapping. Vinkius handles the underlying authentication.

The system logs every tool invocation automatically. You monitor the execution of tools like `get_balance` directly inside the OpenAI dashboard traces. Failed validations trigger clear exceptions in your Python code.

Your client communicates directly with the Vinkius V8 Isolate Sandbox. Customer names, PIX keys, and bank balances read by `list_customers` pass through an ephemeral, zero-trust tunnel. We never store your transaction history.
