call4me adds a phone-calling tool to agents such as Claude Code, Codex, Claude Desktop, ChatGPT, Muse and Grok through a remote MCP server. After loading at least $10 in prepaid credits and signing in, a user gives the agent a request such as booking a restaurant, scheduling a medical appointment, checking stock, handling an internet-service issue or rebooking a flight. The service says calls cost $0.25 per minute in most supported destinations, with higher rates in several listed countries; the maximum estimated cost is held in advance and unused funds are returned, while unanswered, busy and failed calls are free. Every account can call businesses in the United States, Canada, Europe and the UAE from its free US number, while local numbers can be purchased in 14 countries and are charged carrier cost plus monthly renewal. The agent can gather missing details, place the call, answer questions during the conversation and report the outcome. Users may be connected when a person answers, or listen in silently and take over by pressing 1; call4me may also ring the saved phone when identity verification is needed. The service says it sounds like a normal caller, does not pretend to be the user, and discloses that it is AI if sincerely asked. Calls are recorded by Telnyx, with recordings and transcripts available after completion. The site prohibits telemarketing, surveys, unsolicited calls, emergency numbers and premium-rate numbers.
