How to Use the CallFire MCP in OpenAI Agents SDK

Q: How do I connect OpenAI Agents SDK to CallFire?

Use MCPServerStreamableHttp with your Vinkius endpoint URL. The SDK handles the rest via its async context manager.

Q: Can OpenAI Agents SDK read CallFire broadcast campaigns?

Yes, the agent runs listcampaigns to fetch your active outreach efforts. It auto-discovers this capability during initialization.

Q: What tools does this MCP Server provide?

The current toolset focuses on read operations like gettext and listcalls. You cannot send new messages directly through these endpoints.

Connect OpenAI Agents SDK to CallFire for automated voice broadcast and SMS campaign tracking.

Monitor Campaigns with OpenAI Agents SDK

Your production agents need visibility into high-volume outreach. Passing this MCP Server to your agent constructor auto-discovers endpoints for monitoring broadcast performance. Built-in guardrails validate requests before your agent calls `get_campaign` or `list_calls`. You get full tracing in the OpenAI dashboard when the system pulls contact histories.

Audit SMS and Voice Logs

Handoffs between specialized agents work best when they share ground truth. One agent executes `list_texts` to find failed deliveries, while another reviews the specific payloads. Fetching individual records via `get_text` or `get_call` gives your safety systems exact timestamps and routing data. Nothing gets assumed.

Inspect CallFire MCP Server Webhooks

Routing events correctly requires knowing your current configuration. Your agent reads active endpoints using `list_webhooks` to confirm delivery destinations. Digging into specific trigger rules happens through `get_webhook`. You verify exactly where your contact updates from `list_contacts` are heading.

Setup guide

Set up CallFire 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 CallFire tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
