All 6 of its tools are labeled read-only. Overall it scored 95/100 on 5 Nov 2026. A test can only see what the server shows from outside, not what it does with your data behind the scenes. Connect servers from makers you trust.

Its source code and packages.
What a tool quietly does behind the scenes, such as writing a file or calling another service.

Hidden instructions worded in a way our list doesn't know yet.
Tools that could change something. Those are read, never run.

Known security advisories
