Barryyosi/mcp-it ? reverse-engineered prompt

Build me a small Python CLI tool that can take any installed command line app and turn it into something an agent can use inside an instruction file like AGENTS.md or CLAUDE.md.

I want to run it like mcp-it <cli_executable> <target_file> and have it inspect that CLI, collect its commands, options, and short descriptions, then write them into the target file in a clean structured way. If the file does not exist, it should be able to create it. I also want a dry run mode so I can preview what would be added without changing anything.

Make it easy to install and use globally, and keep the project simple and well organized. If you need to look up current docs or best practices for parsing CLI help output, go ahead and check online. Please include a good README with a quick start and a couple of examples, especially one for something like GitHub CLI.
