The geospatial toolkit for AI agents — query, convert, and verify spatial data with zero config. 6 tools for bounding boxes, coordinate projection, H3 indexing
The geospatial toolkit for AI agents. 6 tools, zero config — give any LLM the ability to find, query, convert, and aggregate spatial data using open data. No API keys or signups required to start.
Installation goes through your MCP client rather than a global install: point it at bbox-mcp-server on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
You will need 2 environment variables: MAPBOX_ACCESS_TOKEN, OVERPASS_API_URL. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
get_bounds — Convert and project a bbox across formats and coordinate systemsget_h3_indices — Generate H3 hex cell indices covering a bboxgenerate_share_url — Create a shareable map link for a bboxsearch_overpass — Query OpenStreetMap via Overpass QL within a bbox or radiuslist_osm_tags — Look up correct OSM tags for a categoryaggregate_overpass_h3 — Run an Overpass query and bin results into H3 hexagonsCompare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
