Formats docs-verified: GeoArrow batches (experimental columnar data plane) · MCP server
Access docs-verified: Open source, Apache-2.0 licence (per ENTRY). Public endpoints need no API key or account. Server-attach capabilities need a Honua Server. ENTRY lists HONUA_ADMIN_KEY, HONUA_API_KEY and HONUA_BEARER_TOKEN, which do not appear in the supplied DOCS.

Useful for

Use cases llm-inferred: Inspect and bounded-query a public ArcGIS FeatureServer or OGC endpoint, then map it in MapLibre for a site-constraints review · Build a styled 2D map of WMS or WFS layers as an EIA or planning baseline, using the same typed client for each protocol · Scan an existing ArcGIS web app for classic widgets and migrate it to MapLibre before the ArcGIS JS 6.0 removal · Give a coding agent typed access to live geospatial endpoints for scripted data checks
Audience llm-inferred: GIS analysts · web and GIS developers · geospatial data engineers · planners and ecologists working with agent-assisted queries

Limitations

Constraints llm-inferred: Release status is beta (0.2.2); 26 experimental subpaths may change before 1.0 · The README tracks the development branch; the npm artifact may not include every described capability · It is a client SDK and supplies no datasets itself; coverage depends entirely on the endpoint queried · Entry metadata lists region as Global, and nothing in the DOCS is UK-specific · Server-attach capabilities (8 of 36 claims) need a Honua Server · The columnar data plane is experimental, the Cesium scene surface is beta and Kepler.gl is experimental · Multi-source service roots need an explicit sourceId · Unsupported capabilities throw HonuaCapabilityNotSupportedError · The map path needs maplibre-gl installed as a peer dependency · MCP transport and tool names are not stated in the supplied DOCS
