Connect it
Claude
- In Claude (web, desktop or mobile), open Customize, then Connectors, and add a custom connector.
- Name it Callmins, enter https://callmins.com/mcp and press Continue.
- Under Authentication choose Sign in now (Claude may pre-select No sign-in), then press Add.
- Press Connect, sign in to Callmins and allow access.
- In a chat, turn Callmins on from the tools menu and ask away.
ChatGPT
- In ChatGPT on the web, open Settings, then Apps, then Advanced settings, and turn on Developer mode.
- Press Create app. Name it Callmins, enter https://callmins.com/mcp as the MCP server URL and choose OAuth.
- Sign in to Callmins and allow access.
- In a chat, add Callmins from the + menu, then ask away.
Developer mode is on paid ChatGPT plans. ChatGPT asks you to confirm before the connector changes anything.
Claude Code
- Add Callmins from a terminal:
claude mcp add --transport http callmins https://callmins.com/mcp - Start Claude Code, run /mcp, choose callmins and sign in.
- Ask away in any session.
Codex
- Add Callmins and sign in from a terminal:
codex mcp add callmins --url https://callmins.com/mcp codex mcp login callmins - Ask away in the Codex CLI, IDE extension or desktop app. They share this setting.
What it can do
- Without signing in: list countries, search numbers for sale, and check call and SMS rates.
- Your account: see your balance, numbers, calls, texts and your own call transcripts. Company admins can also see team call activity.
- Orders: prepare a number order or wallet top-up, then check its status.
- Numbers: turn renewal on or off, and connect a number to a voice agent.
- Agents: create an AI phone agent with your menu, plans or prices, have it answer your number, and (for approved company accounts) call people who agreed to hear from you. It says it's an AI, never asks for payment details or codes, and ends the call when asked. Agents follow the agent use policy: no lottery or prize calls, no fraud.
- Voice messages: call someone from your number to read out a short message you write, like a birthday wish. It's announced as an automated message from you, and messages with links, numbers, payment requests or threats are refused.
You stay in control
- The connector can't take payments. It prepares an order and gives you a link. You see the price and pay on callmins.com.
- Verification codes stay private. Text messages shown to your AI app have anything that looks like a code hidden. Read those in the Callmins app.
- Passwords stay private. The connector never receives a password for your number.
- You can disconnect at any time in Settings. The app's access ends immediately.
Examples to try
- “What would a US number in the 415 area code cost on Callmins?”
- “Get me a UK number and give me the link to pay for it.”
- “Connect my number to my ElevenLabs agent and tell me what to enter.”
- “How much did my team call last week?”
- “Call +44 7… from my UK number and say happy birthday from Sam.”
- “Create an agent for my restaurant with this menu and have it answer my number.”
