Smitline MCP server

Your agent can make the call.

Phone calls and meetings for any AI agent. Smitline gives your agent a phone line and a seat in Zoom, Microsoft Teams and Google Meet, talks with people in real time, and reports back to the chat that sent it.

What it does

Ask your agent the way you'd ask a good assistant:

"Call Luigi's and book a table for 4 at 7."

"Call the plumber and see if they can come today. Don't agree to more than $150."

"Join my 3 PM Zoom and take notes for me."

Smitline makes the call, talks with whoever answers in a natural voice, and sends the result back to your chat: what happened, the details you need (times, prices, confirmation numbers), decisions, action items, the full transcript, and what the call cost.

• Calls anyone. Restaurants, offices, plumbers, friends, using your own number through your SignalWire or Twilio account.
• Joins meetings. Zoom, Microsoft Teams and Google Meet, as a participant that listens and answers when it's spoken to.
• Works with your agent. Claude Code, Codex, Cursor, Claude Desktop, OpenClaw, Hermes, and anything that can use MCP, a CLI or a REST API.
• Runs on your computer. One Docker container, your own OpenAI and phone keys, open source under Apache-2.0.

How it works

1. You ask your agent. It writes a short brief: the goal, what to find out, what it may agree to, and what to keep private.
2. Smitline makes the call. It opens with your name and why it's calling, says during the call that it's your AI assistant, and talks in real time using OpenAI's GPT-Live, staying inside the brief.
3. You can follow along. The dashboard on your computer shows the live transcript, and you can take the call over on your own phone at any moment.
4. The result comes back to the chat that asked: the outcome, the details, action items, the transcript, and the cost.
