mcp-man

MCP (Model Context Protocol) is the standard way for AI assistants like Claude to connect to external tools, such as database clients, file systems, web search, and GitHub integrations. Each tool provider runs an MCP server, and there are hundreds of them available. The problem is that figuring out what any given server does, what parameters its tools accept, and what credentials it needs typically requires digging through GitHub READMEs and guessing.

mcp-man is a browser-based UI and command-line tool that solves this. Install it with npm, run mcp-man ui, and you get a local web interface with a registry of 156 MCP servers you can search by name or tag. Pick one, paste in the startup command, and mcp-man connects to it and shows you every tool it exposes, the full input schema for each tool, required parameters, and types. From the same UI you can call any tool live with JSON arguments and see the raw response, without needing to wire the server into an AI assistant first.

For servers that need API keys or other credentials, mcp-man includes an auth wizard that covers 78 servers and provides direct links to get each required token.

Everything in the UI is also available from the command line. You can search for servers, inspect a server's tools, and call a specific tool all from the terminal.

The project is open to adding new servers: edit the registry JSON file and open a pull request. If a server requires credentials, add an env array and the auth wizard picks it up automatically. The project is MIT licensed and written in TypeScript.
