Server

Overview

Server is a Model Context Protocol (MCP) server: One MCP tool contract for telephony — any call provider, hosted, local, or BYOK. In practice that means any MCP-compatible AI assistant can call Server's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the npm package @callmcp/server speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.1.2, published under the MIT license, with source at CallMCP/callmcp on GitHub.

Server is listed under Development on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
