rendezvous-mcp makes outbound HTTP requests to:
- Valhalla routing engine (
VALHALLA_URL, default:https://routing.trotters.cc) — isochrone, route matrix, and directions queries - Overpass API (
OVERPASS_URL, default: public instances) — venue search within polygon bounding boxes
No data is sent to any other service. There is no telemetry, analytics, or tracking.
When the routing engine returns HTTP 402 (Payment Required), the response includes a Lightning invoice. After payment, the user stores a macaroon + preimage via store_routing_credentials. These credentials are held in memory only (per-session) and are never persisted to disk.
If you discover a security vulnerability, please email security@trotters.cc rather than opening a public issue. We will respond within 48 hours.
Only the latest major version receives security fixes.
