Data offered llm-inferred: ArcGIS REST portal items, feature layers and query results · geocoding of named places · drive-time polygons · geometry intersection results · local GIS exports read from disk (e.g. GeoJSON, FileGDB) · layers drawn on a live browser map (mappi)
Coverage llm-inferred: Global (catalogue region; actual data depends on the ArcGIS portal queried)
Update frequency llm-inferred: On demand: each request queries the ArcGIS REST endpoint live
Formats llm-inferred: JSON (ArcGIS REST responses) · GeoJSON · FileGDB · MCP streamable HTTP
Access docs-verified: Apache-2.0 licence. ArcGIS REST access needs an ArcGIS portal login via OAuth 2.0 with PKCE (ARCGIS_PORTAL_URL, ARCGIS_CLIENT_ID). Local work needs no portal configuration.

Use cases llm-inferred: Site screening: geocode a development site and check its boundary against planning or environmental layers via the geometry service · Access assessment: 10-minute drive-time catchment around a site or asset for response or access planning · Client briefings: draw query results and drive-time areas on a live map with a summary table in chat
Audience llm-inferred: GIS analysts · planners · environmental consultants · civils engineers

Constraints docs-verified: Each run makes credit-billed drive-time solves · ArcGIS REST needs a portal login and a registered OAuth redirect URL (localhost callback on ports 9500-9600) · Requires Node 22.19 or newer and pi 1.0 or newer · The arcgis_request tool exists only in pi, through the arcgis-rest extension · No ArcGIS CLI or ArcGIS MCP server; ArcGIS is accessed via REST only · The extension handles only streamable-http MCP transport; other transports are reported and skipped
