Telnyx, the full-stack communications platform enabling AI-powered voice, messaging, and automation, unveiled the beta release of its Local Model Context Protocol (MCP) Server. This new offering gives developers the power to run Telnyx’s robust API suite directly on their local machines—delivering secure, low-latency access to telephony and AI tools without the need for cloud infrastructure.
Designed for seamless compatibility with top MCP clients such as Claude Desktop and Cursor, the Local MCP Server lets developers build, test, and manage voice calls, SMS and MMS messaging, phone numbers, and AI assistants—all within a local development environment.
“This release is all about putting power and flexibility into the hands of developers,” said David Casem, CEO of Telnyx. “Whether you’re building AI agents or prototyping telecom features, running locally gives you more control, faster iteration, and tighter integrations.”
