The hosted Librarian provides source-backed capability guidance. Public chat includes five guest questions, then requires a free account to continue. Registered free accounts include 20 chats per UTC day, subject to service availability. MCP requires an authorized service bearer token; Librarian MCP tools additionally require account entitlement and billing integration. No anonymous MCP bypass. Data operations use existing authorized tools. Road geometry does not imply routing or live traffic. Preserve source attribution and coverage limits.
