Automate accounting with OpenAI Agents SDK

Your agent can pull live financial data using `list_invoices` and `list_expenses` to reconcile your books. It processes your data as it arrives, keeping your internal records updated without manual entry. Use `get_invoice_details` to verify billing status before your agent takes any action. This allows your production system to check current invoice states against your business logic.

Manage client billing with tool auto-discovery

The SDK detects available functions like `list_clients` and `get_client_details` automatically. You spend less time mapping endpoints and more time building agent logic for your business workflows. Your agent handles routine queries by calling `list_time_entries` and `list_project_tasks` directly. It identifies billable hours and prepares accurate records for your approval.

Track project performance and payments

Monitor your cash flow by having your agent run `list_payments` against your active records. You get immediate visibility into which clients have settled their accounts. Combine `list_active_projects` with your own task data to keep your team aligned. The server provides the raw numbers, and your agent ensures the billing matches the work done.

Setup guide

Set up FreshBooks 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 FreshBooks tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about FreshBooks MCP in OpenAI Agents SDK

You instantiate the server using the streamable HTTP parameters and inject it into your agent constructor. The SDK handles the connection, letting your agent discover all twelve accounting tools immediately.

Yes. You can implement validation logic within your agent to gate any write operations. Since the agent only reads data by default, you control exactly when and how updates occur.

Absolutely. You can add custom validation functions to ensure the output from `get_invoice_details` matches your internal business rules before the agent proceeds.

The MCP server uses standard HTTP transport. If the connection fails, the SDK raises an exception that your agent can catch, allowing you to retry or log the error.

Your financial data stays within the secure Vinkius sandbox. The agent only accesses specific records when you explicitly call tools like `list_expenses` or `list_payments`.
