Check Bill Details with OpenAI Agents SDK

The `get_bill_details` tool pulls full legislative data for any specific bill you name. You'll get everything—the status, the sponsors, and all the historical context—directly into your agent. This works perfectly for building mission-critical agents that need reliable data.

List Members via MCP Server

Use `list_congress_members` to pull names of both current and past U.S. Congress members. Your agent can instantly cross-reference these lists, making sure every data point it processes is tied back to an official congressional record.

Review Congressional Sessions

The `list_congress_sessions` tool gives you the start and end dates for specific Congresses (like 118th or 117th). This lets your agent scope its search precisely, so it only processes data relevant to the time period you care about.

Setup guide

Set up U.S. Congress 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 U.S. Congress tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
