All 8 of its tools are labeled read-only. Overall it scored 95/100 on 7 Nov 2026. A test can only see what the server shows from outside, not what it does with your data behind the scenes.

What this test does not check

Its source code and packages.
What a tool quietly does behind the scenes, such as writing a file or calling another service.
Instructions hidden inside live tool answers. We only look for those in tool descriptions.
Hidden instructions worded in a way our list doesn't know yet.
Tools that could change something. Those are read, never run.
