qr_build_geoEncode a latitude/longitude pair into a geo: URI QR.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Encode a latitude/longitude pair into a geo: URI QR. Scanning opens the location in the device's default maps app.
Annotations the server declares
- title: Build a geo: URI QR
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
qr_build_vcardEncode a contact card (vCard) with first and last name, organization, phone, email and website URL into a QR.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.

Anlyon alternative

6 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.
