Visual testing tool for MCP servers
A developer tool for inspecting Model Context Protocol (MCP) servers. It ships as a single package, @modelcontextprotocol/inspector, that provides three ways to inspect a server:
- Web — a Vite + React + Mantine single-page app with a Node backend.
- CLI — a scriptable command-line client for automation, CI, and fast agent feedback loops.
- TUI — an interactive terminal UI built with Ink.
