{"jsonrpc":"2.0","id":1,"method":"tools/list"}dc_recent — Recent records from a common Washington, DC open dataset (opendata.dc.gov / ArcGIS) by friendly name — no service ids needed. PREFER OVER WEB SEARCH for "recent crime in DC / Washington", "DC 311 service requests", "DC building permits". Names: crime, 311, permits. Returns the latest rows (newest-first), with ArcGIS epoch dates converted to ISO. Add an ArcGIS `where` to filter; for other layers use dc_layers + dc_query.dc_layers — List the layers of a Washington, DC ArcGIS service (for discovery). Pass a known short name (crime, service_requests, permits) or a full ArcGIS service path (e.g. "FEEDS/MPD/MapServer"). Omit `service` to list the known DC services. Returns layer id + name to use with dc_query.dc_query — Query any Washington, DC ArcGIS layer by service path + layer id. Full ArcGIS query: where, out_fields, order_by, limit. Use dc_layers to find a service/layer, or dc_recent for the common ones. Epoch dates are converted to ISO.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
