MCP Inspector

A developer tool for testing and inspecting MCP servers.

New this week

What it does

MCP Inspector is a tool for developers who build MCP servers, the small programs that give AI assistants extra abilities.

It lets you connect to a server and check what it offers, through a web page, a command line, or a terminal interface.

It is meant for testing and debugging during development, and it stores any secrets it handles in your computer's secure keychain when one is available.

Who it's for
