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.
Every response includes a shareable verification link to vibhorsingh.com/boundingbox — click it to visually confirm results on an interactive map. No other MCP server does this.
You don't have to be a GIS professional to make use of this. Any AI agent with this MCP server can answer spatial questions using real OpenStreetMap data and not spit out hallucinated garbage.
| Ask your AI agent... | What happens under the hood |
|---|---|
| "How many EV chargers are in downtown Denver?" | Overpass query → H3 hex binning → density analysis |
| "Is there a hospital near this Airbnb?" | POI search with structured tags → map verification link |
| "Find all playgrounds within 1km of this address"* | Overpass query + radius filter → pinned results on a shareable map |
| "Convert this WKT to GeoJSON in EPSG:3857" | Format conversion across 6 inputs, 9 outputs, 3,900+ projections |
| "Show me all bike-share stations in Amsterdam" | Curated OSM tags → Overpass query → results on map |
| "Compare park density across Seattle neighborhoods" | Overpass + H3 aggregation → hex-binned spatial analysis |
Every answer comes with a link. Click it, see if the AI got it right and you can also share it with someone else.
Most AI tools give you text you have to trust. This one gives you an interactive map you can check and verify!
npx -y bbox-mcp-server and you're running.| The problem | How bbox-mcp solves it |
|---|---|
| "I have WKT but the API needs a GeoJSON bbox in EPSG:3857." | Parses 6 input formats, projects to 3,900+ EPSG codes, outputs in 9 formats — in one call. |
| "I keep getting the wrong OSM tags for Overpass queries." | list_osm_tags returns curated tag combos. No more hallucinated amenity=grocery. |
| "How many hospitals are in this district?" | aggregate_overpass_h3 queries Overpass and bins results into H3 hexagons server-side. |
| "Is this bounding box actually correct?" | Every response includes a clickable map link for visual verification. |
| Tool | What it does | Key params |
|---|---|---|
get_bounds | Convert and project a bbox across formats and coordinate systems | bbox, epsg, format, coord_order, zoom |
get_h3_indices | Generate H3 hex cell indices covering a bbox | bbox, resolution, compact |
generate_share_url | Create a shareable map link for a bbox | bbox |
search_overpass | Query OpenStreetMap via Overpass QL within a bbox or radius | bbox, query, limit, radius_meters |
list_osm_tags | Look up correct OSM tags for a category | category |
aggregate_overpass_h3 | Run an Overpass query and bin results into H3 hexagons | bbox, query, resolution |
All tools accept location (natural language, requires Mapbox token) or bbox (coordinates,
