Questions
Which calling MCP servers work in Claude and ChatGPT?
Any remote MCP server over streamable HTTP. CallForMe, ClawCall, and Pine are remote servers you add by URL. PhoneBooth and open-source builds can run locally.
Which one needs the least setup?
CallForMe needs only the URL https://callforme.tel/mcp and one click on Connect. No email or form. You add a prepaid balance once, through a link your agent shows you at the first call.
Which is cheapest?
For heavy use, ClawCall's $4.99 per month unlimited plan. Per minute, PhoneBooth at $0.07. For a few calls a month, CallForMe at $1 per answered call and nothing when unanswered.
What should a good calling MCP server do?
Handle phone menus and hold, disclose that it's AI, let your agent answer questions mid-call, return structured results, and keep guardrails like blocked emergency numbers and opt-out lists.
