call4me — Claude Code MCP server: what it does, how to install
Your agent dials businesses itself: books, reschedules, cancels, asks questions, sits on hold, then reports back with a transcript.
claude mcp add --transport http call4me https://call4.me/mcpWhat call4me does
call4me is a remote MCP server at https://call4.me/mcp over streamable HTTP. Hand an agent a task that needs a phone call and it dials the business, works through the keypad menu, waits on hold, speaks to whoever answers, and hands back the outcome plus a transcript. It can ring you in so you join the call yourself.
Sign-in happens in the browser with Google or X. No browser in reach? Create a key on https://call4.me/account, then point the client at https://call4.me/mcp/<key>, or send Authorization: Bearer <key> to /mcp.
Calls come out of prepaid credits, packages start at $10. The from number has a limit worth knowing: dialling from your own verified number reaches businesses inside that number's country only. The callback still arrives from a call4me number.
What it helps with
- Book a table without dialling the number yourself
- Move a dentist appointment by voice
- Cancel a subscription over the phone
- Ask a shop whether something is in stock
- Read a transcript of what the business actually said
Example prompts for the agent
- Call the clinic in
contacts.mdand move my appointment to Friday afternoon. - Ring the restaurant and book a table for tonight; if they're full, ask about the nearest slot.
- Get through to my provider's support, wait on hold, and find out why the internet bill went up.
