When were Telnyx MCP Server's facts last verified?
2026-08-20. Each fact on this page links to the sources used to verify it.
Telnyx publishes an MCP server for its communications API. It lives in
the telnyx-node monorepo at packages/mcp-server, is distributed as
the npm package telnyx-mcp, and runs locally over stdio via
npx -y telnyx-mcp@latest with Telnyx API credentials in the
environment. The package is Stainless-generated from the Telnyx API and
sits in Telnyx's own GitHub organization, which grounds first-party
authority.
One catalog caveat drives the record's shape. The ranked MCP 500 row for
io.github.team-telnyx/telnyx points at the telnyx npm package, which
is the API SDK ("Official TypeScript library for the Telnyx API"), not
the MCP server. This record covers the actual MCP server (telnyx-mcp)
that the same monorepo ships. No surface names a supported MCP
specification revision, so spec_status is unknown.
