Phone Call MCP Servers Compared (2026)
A phone call MCP server lets an AI assistant such as Claude or ChatGPT place or answer real phone calls through the Model Context Protocol. This page lists the phone call MCP servers people ask about most, with what each does, whether it is hosted, and its public pricing. Facts come from each vendor’s own page; where we could not confirm a fact, we left it out.

How to choose
You want your assistant to make a call for you today. A hosted server is the short path: add one URL to Claude or ChatGPT and sign in. CallMCP, DialMCP, Mitra, GlobCall and Callsy work this way.
You already run on a carrier account. Twilio MCP and the Vonage Telephony MCP Server wrap the carrier’s own API, so you bring credentials and pay that carrier’s usage.
Your agent also needs its own line that answers. CallMCP gives the agent a dedicated number that answers inbound calls, takes voicemail and hands off to a person, alongside outbound calls and meetings.
You build voice agents as a product. Vapi and Bland expose their voice-agent platforms over MCP so a coding agent can configure them.
What CallMCP adds
CallMCP is one hosted phone call MCP server with 180+ tools. High-impact changes, such as buying a number or changing a live agent, wait for the owner’s approval. Every call request takes an idempotency key, so a retry does not ring the phone twice. Read the safety rails, the call lifecycle and pricing.
Example prompts: “Call my dentist and move my cleaning to Friday.” “Call Rosa’s Pizza and ask if they can cater 20 people on Saturday.” “Join my 2pm Zoom, take notes, and send me a summary.”
