What it does

Turns any existing CLI program into a JSON‑API that AI agents can call as if it were a native tool.

When to use it

•You need an AI agent (e.g., ChatGPT, LangChain) to run a legacy command‑line tool that has no API.
•Your startup wants to automate a bash script or system utility without rewriting it in code.
•You want to expose a CLI (git, ffmpeg, curl, etc.) to a no‑code workflow platform or chatbot.

Ready-to-paste prompt

curl -X POST http://localhost:8000/run -H "Content-Type: application/json" -d '{"tool":"ffmpeg","args":["-i","input.mp4","-c:v","libx264","output.mp4"]}'

Heads up: CLI‑Anything only works with Python 3.10+ and requires the target binary to be in your system PATH; if the command isn’t found, the server returns a 404 error.

How CLI-Anything works

Codeflow

Free to inspect

CLI-Anything is a very large Python project (~223k lines across 1074 code files, plus 237 test files). You install it into your AI tool with one command; there is nothing to run yourself. Last commit this month, Apache-2.0 license, has a test suite.
