Developers reach for this to see what a server actually exposes before wiring it into an assistant. List its tools, call one by hand with your own inputs, read its resources, or open an interactive shell and poke around. It can also stand up a fake server for testing, sit in the middle and log traffic, block tools you would rather nobody reach, and manage the settings files that Claude Desktop, Cursor, VS Code, and Windsurf read. Install it with Homebrew or Go.

Installation

mcptools FAQ

Who is this for?
Developers and tinkerers. It is a terminal tool, not something you chat with.
How do I install it?
On a Mac, brew tap f/mcptools then brew install mcp. On Windows or Linux, go install from source.
Can I use this to check what a server does before adding it to my assistant?
Yes. One command lists every tool, resource, and prompt the server publishes.
Does it work with servers hosted on the web?
Yes. It handles local programs and web addresses alike, picking the right connection method automatically.
Is there anything visual?
Yes. A web command starts a browser interface, and output can be printed as tables, plain JSON, or a formatted view.
Do I need an assistant installed to use it?
No. It talks to servers directly, which is what makes it handy for debugging.
