DialMCP

DialMCP gives your agent (i.e. Gamut, Claude, Codex) the ability to place phone calls withyour actual phone numberand speak on your behalf.

One endpoint:https://mcp.dialmcp.com/mcp— OAuth sign-in with your phone number, no API keys.

Your agent callsplace_callwith a phone number and an objective. DialMCP does the rest and hands back a structured result.

Calls go out with your phone number so recipient seesyoucalling — and can call you back.

Every call returns a full transcript, a link to the audio recording, and a structured resolution: outcome, summary, commitments made, follow-ups needed.

It presses the keys, answers voice menus, waits silently through hold, and detects voicemail (it hangs up rather than leaving one).

The first thing any human hears: it's an AI assistant, calling on your behalf, and the call is recorded. Always.

place_callreturns instantly with a call ID; your agent pollsget_callfor progress. Works within every client's tool timeout.

Every call complies with calling-hours enforcement, rate limits, do-not-call registries, objective screening, and hard blocklists.

Try asking the agent to call a friend to test it out.
- Get theGamut Desktop app.
- OpenSettings → Connectorsand chooseAdd MCP server.
- Paste the server URL:https://mcp.dialmcp.com/mcp(transport: HTTP, auth: OAuth).
- Complete the sign-in window — enter your phone number and the SMS code to verify it as your caller ID.
- Enable the connector in a session and ask:“Call Tosca and book a table for two at 7:30 tonight.”

- Add the block above to~/.codex/config.toml(Codex's MCP servers section).
- Restart Codex; approve the OAuth browser prompt the first time the server is used.
- Tool calls are async — tell Codex to pollget_callrather than wait on the line.

Everything you need to know about how DialMCP places calls, protects your number, and keeps every call compliant.

Whose number shows up on the callee's phone?

Yours. During sign-up you verify your own number via SMS, and every call the agent places presents that number as the caller ID. Callees can call or text you back directly — DialMCP never hides behind a random number.

Does the person being called know it's an AI?

Always. The agent's first words to any human are a disclosure — that it's an AI assistant, who it's calling for, and that the call is recorded. This is enforced in the calling system and independently checked after every call, not left to the model's discretion. If someone objects to talking to an AI, the agent apologizes and ends the call.

US and Canadian numbers, between 8:00 and 21:00 in thedestination'slocal time. Emergency services, premium-rate lines, and high-fraud number ranges are blocked outright and can never be called. See thesafety pagefor the full guardrail list.

A structured resolution (achieved / partially achieved / not achieved, with a summary, any commitments made, and suggested follow-ups), the full turn-by-turn transcript, and a signed link to the audio recording. For the full walkthrough of having an AI assistant place the call, seehow to make a phone call with an AI assistant.

The agent confirms it on the spot and the number goes onto a permanent do-not-call list — enforced before any future call is placed, by any user. There's also aself-serve opt-out pageanyone can use, no account needed.

Yes — any client that supports remote MCP servers with OAuth works: claude.ai and Claude Desktop (Settings → Connectors → Add custom connector), ChatGPT developer-mode connectors, Cursor, and more. Same URL everywhere. DialMCP is not a standaloneAI phone call app; it attaches to the assistant you already use.

Yes during launch. DialMCP is in a pilot and early-access period: it is free of charge, limits are conservative, and pricing may be introduced later with notice. No API key and no credit card. Seewhat $0 includes.

Start with the official Python or TypeScript SDK, register tools, and pick stdio for local hosts or Streamable HTTP plus OAuth 2.1 for a remote server. DialMCP is the hosted phone-call version of that design. Seehow to build an MCP server.
