Telnyx MCP Server 2025: Features & Setup Guide

Overview

Telnyx Local MCP Server is the official Telnyx MCP server that enables interaction with telephony, messaging, and AI assistant APIs. It allows MCP clients such as Claude Desktop, Cursor, Windsurf, OpenAI Agents, and others to manage phone numbers, send messages, make calls, and create AI assistants. The server exposes a suite of MCP tools across categories including Assistant Tools, Call Control Tools, Messaging Tools, Phone Number Tools, Connection Tools, Cloud Storage Tools, Embeddings Tools, and Secrets Manager Tools. It supports a webhook receiver for Telnyx webhooks (with optional ngrok tunneling), configuration via Claude Desktop, and tool filtering to enable or disable specific functionality. This Python-based server is run with uvx, and the README provides steps to clone the repository, set TELNYX_API_KEY, and run locally. The project emphasizes code quality with Ruff, provides development setup, and includes troubleshooting guidance. Note: this Python-based MCP server is deprecated in favor of an official TypeScript version, with migration guidance to the Telnyx Node repository.
