Telephony

Telephony MCP Server is an open-source Model Context Protocol (MCP) server that enables LLM applications to perform real-world telephony actions, such as making voice calls and sending SMS messages via the Vonage API. It is intended for developers building advanced AI-powered agents or LLM integrations, and can be used with clients such as LangChain or Claude Desktop to extend LLM capabilities beyond content generation. The solution features tools for voice calling, SMS, and an event callback server, running via Python or Docker.
