- Warning: 9 of 9 tools do not say whether they can change things.
Nothing failed, but there is something to know or fix. Public audit: we connect as an AI client would, list the tools and check what they say. We do not run them. How we audit
- Does it work?
- YesConnected in 358 ms.
- Sign-up?
- None neededIt answered without any account or key.
- Can it change things?
- Doesn't sayIts tools do not say whether they only read, so treat them as able to change things.

What we checked
Security
Passed: Connections are encrypted (HTTPS).
Passed: No hidden instructions found in tool text.
Safety labels
Warning: 9 of 9 tools do not say whether they can change things.
MCP lets a server label each tool as read-only or destructive, so clients can ask the user before risky calls. Unlabelled tools are treated as able to change things.

Passed: The server responds.
Tools (9)
As the server describes them. The labels are the server's own: it says whether each tool only reads or can change things.
