This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
Exfil surface
Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.
360 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 3 outbound tools breaks every one.
- Reads private data5
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write24
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out3
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

The endpoint served tools/list without credentials, and the list has 15 tools that change things (1 destructive, 3 irreversible, 11 write). Whether a call also works without credentials was not tested: tools are never called.
