How to Use the everbill MCP in OpenAI Agents SDK

Q: How do I connect the everbill MCP Server to my OpenAI Agents SDK pipeline?

Install the SDK, then initialize the connection using MCPServerStreamableHttp pointing to your Vinkius endpoint. Pass this server instance in your mcpservers list to let your agent discover everbill tools like listproducts and createinvoice.

Q: How does everbill tool caching work in the OpenAI Agents SDK?

Set cacheToolsList=True when configuring your streamable HTTP server in Python. This keeps the SDK from querying the everbill tool schema on every turn, making your getcustomer and listproducts calls faster.

Run production agents that manage everbill invoices and customers safely using OpenAI Agents SDK guardrails.

Safe billing updates with OpenAI Agents SDK

Prevent your agents from writing bad financial data by applying OpenAI Agents SDK guardrails to the everbill `create_invoice` tool. This setup checks raw inputs like tax rates and line items before the tool executes, keeping your billing records clean. You can monitor every single `create_customer` call initiated by your agent directly inside the OpenAI developer dashboard. If an agent tries to pull client profiles, the dashboard displays the exact parameters sent to everbill.

Smart agent handoffs for client onboarding

Build a specialized onboarding agent using the OpenAI Agents SDK that gathers client details and then hands off to a billing agent to run `create_customer`. This prevents your primary customer-facing agent from needing direct access to your everbill accounting tools. The billing agent can then independently run `get_customer` or `list_customers` to verify the profile was created correctly. This division of labor keeps your financial data isolated and secure.

Fast everbill MCP Server discovery

Registering this MCP Server with `MCPServerStreamableHttp` lets your OpenAI Agents SDK setup instantly discover all seven everbill tools, including `list_invoices` and `get_invoice`. You do not have to write custom API wrappers for your accounting. Turn on tool caching in your Python configuration to speed up how fast your agent reads everbill products via `list_products`. Your production agents get immediate access to billing data without lagging.

Setup guide

Set up everbill 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 everbill tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about everbill MCP in OpenAI Agents SDK

Install the SDK, then initialize the connection using `MCPServerStreamableHttp` pointing to your Vinkius endpoint. Pass this server instance in your `mcp_servers` list to let your agent discover everbill tools like `list_products` and `create_invoice`.

Yes, you can write custom verification logic in your Python code to intercept calls to `create_invoice`. The agent can run `list_invoices` first to check if a duplicate everbill record exists before proceeding.

Set `cacheToolsList=True` when configuring your streamable HTTP server in Python. This keeps the SDK from querying the everbill tool schema on every turn, making your `get_customer` and `list_products` calls faster.

Define a specialized billing agent in the OpenAI Agents SDK that exclusively owns the everbill `create_customer` tool. Your primary routing agent can hand off the conversation context to this billing agent once it collects the necessary everbill customer details.

All everbill customer details, invoices, and product lists are processed in a secure, isolated V8 sandbox on Vinkius. Your OpenAI Agents SDK setup connects via an encrypted HTTP transport, meaning your private financial records never leak into public training sets.
