    Questions about the MCP server

    What is the Leximo MCP server?+

    It is an open-source Model Context Protocol server that exposes Leximo's AI calling agent as tools your LLM client can call. Once installed, Claude can schedule real phone calls, check their status and read transcripts on your behalf.

    Which clients does it work with?+

    Any MCP-compatible client. It is tested with Claude Desktop and Claude Code, and runs over stdio via npx, so no server hosting is required on your side.

    Do I need a paid Leximo plan?+

    You need a Leximo account and an API token. Calls consume credits from your account, and the server itself is free and MIT licensed.

    Where do I get the API token?+

    Sign in at calls.leximo.ai and copy the access token from your profile page, then pass it to the server as the LEXIMO_API_TOKEN environment variable.

    Does Claude place the call itself?+

    No. Claude creates an assignment through the MCP tools, and Leximo's voice agent places the actual phone call over the telephony network, then returns the result and transcript.
