Security profile

Exposure: Limited

Runs commands or loads code on your machine, but does not reach secrets or other agents.

What this server can reach, from a static read of the shipped code. Nothing was executed and nothing here is a verdict: a browser tool has to run commands and an API wrapper has to call its API. Decide what fits your setup.
