- Warning: 3 of 3 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 96 ms.

- 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: 3 of 3 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.
- get_climate_data
- find_stations
- get_climate_normals
Tools
Passed: 3 tools listed.
Passed: Every tool describes its inputs with a valid schema.
Protocol
Passed: The MCP handshake works (Streamable HTTP).
Passed: Protocol version 2025-11-25 (latest).
Passed: Unknown requests are refused.
Connection
Passed: The server responds.
Tools (3)
As the server describes them. The labels are the server's own: it says whether each tool only reads or can change things.
