This one needs environment variables set before it will start: OSM_USER_AGENT (Identifying User-Agent sent to all OSM services (Nominatim requires one)), ORS_API_KEY (Optional OpenRouteService key; switches routing/matrix/isochrones to ORS), OSM_ALLOW_TOOLS (Comma-separated tool names or list_* prefixes to register; 'essential' selects a curated preset (default: all tools)), OSM_DENY_TOOLS (Comma-separated tool names or list_* prefixes to remove from whatever OSM_ALLOW_TOOLS left). The author declared them in the registry entry; get the values from the project itself.
