How to Use the Moneybird MCP in OpenAI Agents SDK

Q: Does the OpenAI Agents SDK support caching for Moneybird tool schemas?

Yes, set cacheToolsList=True in your OpenAI Agents SDK parameters to prevent redundant network requests. This keeps your agent fast when it repeatedly checks Moneybird listinvoices or getinvoice.

Let your OpenAI Agents SDK run your Moneybird accounting with built-in guardrails that validate every transaction before execution.

Validate Moneybird Workflows via OpenAI Agents SDK

The `list_workflows` tool lets your OpenAI Agents SDK pull your active Moneybird accounting workflows to verify compliance before executing changes. This setup hooks your OpenAI system to your Moneybird ledger using our MCP server, letting you pull workflows with `list_workflows` and verify they match your business rules. The built-in safety guardrails in the OpenAI Agents SDK mean you can audit the plan in your terminal before it touches real Moneybird financial data. If the agent tries to push an invalid change to Moneybird, the OpenAI Agents SDK catches it before execution. You get a clean trace on your OpenAI dashboard showing exactly where the Moneybird ledger logic failed, keeping your `list_ledger_accounts` clean and accurate without manual babysitting.

Automate Invoice Audits and Reconciliation

The `list_financial_mutations` tool pulls your latest Moneybird bank feed directly into your OpenAI Agents SDK reconciliation loop. Your OpenAI agent uses these mutations to pull recent bank activity and matches those lines against open Moneybird invoices retrieved via `list_invoices`. When the OpenAI Agents SDK finds a match in your Moneybird records, it flags it for execution. If it hits an edge case, the OpenAI agent hands off the task to a specialized human-in-the-loop agent, ensuring you never misreconcile a Moneybird payment.

Track Estimates and Contacts on Autopilot

The `list_estimates` tool tracks all your active Moneybird proposals so your OpenAI Agents SDK can follow up on unsigned deals. By calling `list_estimates` and `list_contacts`, the OpenAI agent checks which Moneybird proposals are outstanding and who needs a follow-up. When a new lead signs on, the OpenAI Agents SDK uses `create_contact` to instantly set up their profile in Moneybird. Your sales reps do zero data entry, and your Moneybird accounting records stay perfectly mirrored with your OpenAI CRM agent.

Setup guide

Set up Moneybird 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 Moneybird tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Moneybird MCP in OpenAI Agents SDK

Install the OpenAI Agents SDK and use the streamable HTTP client with your Vinkius endpoint. Pass the Moneybird server instance directly into your Agent constructor to let the OpenAI system auto-discover all accounting tools.

Yes, you can control tool access directly in your OpenAI Agents SDK configuration. This prevents the agent from calling sensitive Moneybird tools like `list_ledger_accounts` while still allowing it to run `create_contact` for new leads.

Yes, set `cacheToolsList=True` in your OpenAI Agents SDK parameters to prevent redundant network requests. This keeps your agent fast when it repeatedly checks Moneybird `list_invoices` or `get_invoice`.

The OpenAI Agents SDK relies on the server to handle Moneybird rate limiting under the hood. When your agent calls `list_purchase_invoices` or `list_recurring_invoices`, the connection manages retries automatically to prevent crashes.

Your Moneybird financial mutations and ledger accounts never touch public logs during OpenAI Agents SDK execution. All traffic runs through a zero-trust V8 sandbox, meaning your private balance sheets stay encrypted and isolated from other processes.
