- Warning: 3 of 14 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 568 ms.
- Sign-up?
- None neededIt answered without any account or key.
- Can it change things?
- YesSome tools say they can change things, and others do not say.

What we checked
Security
Passed: Connections are encrypted (HTTPS).
Passed: No hidden instructions found in tool text.
Safety labels
Warning: 3 of 14 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.
- service_status
- overpass_query
- find_features
Note: 2 tools are labelled as able to change things.
Expected for tools that send, write or buy. Your AI client should ask before calling them.
- geo_jobs
- geo_style
Tools
Passed: 14 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 (14)
As the server describes them. The labels are the server's own: it says whether each tool only reads or can change things.
