What's in it
- Data offered docs-verified
- Wikipedia dumps (jawiki full-text search) · OpenStreetMap place names and POIs per country (osm_<country>) · GeoNames worldwide place names · Overture Maps data (overture_japan)
- Coverage llm-inferred
- Global for GeoNames; OpenStreetMap by country; Overture Japan
- Update frequency docs-verified
- Manual: re-run the ingest container to refresh dumps; no schedule stated
- Formats docs-verified
- REST API (HTTP /v1/...) · MCP (HTTP endpoint /mcp) · SQLite (FTS5) local index
- Access docs-verified
- Free, self-hosted via Docker Compose; code under MIT; underlying data carries its own licences (CC BY-SA 4.0, ODbL 1.0, CC BY 4.0, CDLA/Apache 2.0)
Useful for
- Use cases llm-inferred
- Offline GeoNames place-name lookup to geocode site and locality names in desk studies · OpenStreetMap POI search for mapping nearby features as constraints context · Local gazetteer for client-facing reports, with attribution and ODbL/CC BY-SA compliance tracked
- Audience llm-inferred
- GIS analysts · desk-study environmental consultants · planners · developers integrating MCP tools
Limitations
- Constraints llm-inferred
- Docs give no UK-specific dataset; the ENTRY region is Global and examples are Japan-focused · Entry lists only the geonames and overture_japan tools; the Wikipedia search described in the docs is not among them · Sources must be ingested locally before use; jawiki build takes 2-6 hours and each source needs 2 GiB memory · Refresh is a manual re-ingest with no update schedule · Self-hosted server required; no hosted option stated · Data licences impose attribution and share-alike obligations when DB or results are distributed · MCP transport type is not stated in the docs
