MCP Ts Core runs on your own machine — the client starts it, so there is no endpoint to ping. 30 991 installs a week from npm. Last commit 26 Oct 2026.
Agent-native TypeScript framework for building MCP servers.

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
