Nothing serious here today
Today is the operative word: we check Call2Me every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

call2me
call2me_add_campaign_contacts
Adds contacts to a campaign from a JSON list. Numbers must be real E.164 numbers supplied by the user; never invent them.
call2me_add_knowledge_base_sources
Adds text and/or URL sources to an existing knowledge base.
call2me_bind_number
Binds a phone number to an assistant, which then answers calls to that number. Replaces any existing binding.

call2me_cancel_schedule

Creates a checkout link for buying a number. DOES NOT BUY and DOES NOT CHARGE — the user confirms on the payment screen themselves. Use this path when the balance is insufficient.
call2me_create_agent
Creates a new voice assistant. Do not call it unless the user asks explicitly; do not invent fields such as name and language — ask.
call2me_create_campaign

Call2Me — questions
Answers built from our own checks of this server.
What can Call2Me do?
It exposes 79 tools, read directly from the server on our last check. Among them: call2me_add_campaign_contacts, call2me_add_knowledge_base_sources, call2me_bind_number, call2me_campaign_action, call2me_cancel_schedule, call2me_checkout_number and 73 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is Call2Me working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 128 ms. The bar chart above shows every period we have measured.
How do I connect Call2Me?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Call2Me need an API key?
No. Call2Me completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 79 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Call2Me?
It answers our handshake in 128 ms on average, which is faster than 79% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
