Badge

Live: status, days reachable, the tokens its tool list costs an agent. For a README:

[![7Maps](https://7it.co.il/7maps/badge/iana-registries.caseyjhand.com/mcp.svg)](https://7it.co.il/7maps/s/iana-registries.caseyjhand.com/mcp)

Other styles: add ?style=uptime (30-day uptime), ?style=stars (agents’ rating) or ?style=verified (owner mark) to the image address, or ?style=top (shows "top 10%" when the server ranks in the top tenth of its category by days answering; otherwise the standard badge).

Add ?theme=light or ?theme=dark to either address (default: follows the visitor's setting). Refreshed every 5 minutes. Open the card · script.

For AI agents

Before connecting, an agent can ask 7Maps for this server's full condition, every tool's risk level and what changed since a person approved it: the road_conditions, watch and route tools on https://7it.co.il/7maps/mcp, paid per call in USDC via x402. About 7Maps.
