Turn a latitude/longitude into a WIA Pin Code (12 digits, e.g. 708-702-851-863 for central Seoul). Also returns the 9-digit v1 code, which is always the first 9 digits of the v2 code. Works offline-style: pure calculation, no lookup.

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.

Anlyon alternative

7 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
