Bbox Mcp Server

iamvibhorsingh/bbox-mcp-server

Connects Claude to OpenStreetMap via the Overpass API and adds H3 hexagon binning for spatial aggregation. You get six tools: coordinate conversion across 3,900+ EPSG projections, POI search with OSM tags, H3 index generation, and Overpass queries that return structured results. Every response includes a shareable map link to vibhorsingh.com/boundingbox where you can verify the AI's answer visually. No API keys required to start, though adding a Mapbox token enables natural language location search. Useful when you need Claude to answer questions like "find all bike shops within 1km" or "compare park density across neighborhoods" using real geodata instead of hallucinations. Zero config setup via npx.

Readme

🌍 bbox-mcp-server

FREE Geospatial tools for AI agents, with results you can inspect on a map.

Search OpenStreetMap, convert coordinates, generate H3 grids, calculate routes, and sample terrain elevation. 11 MCP tools, no API keys required to get started. Spatial results include shareable links to the interactive map.

Try asking

“Find cafes near Times Square.”
“Find me pizza near the Colosseum?”
“Eiffel Tower to the Louvre: walk or bike? Compare the routes.”
“Where are Manhattan’s coffee hotspots?”
“EV road trip: find chargers within 5km of Monterey.”
“How high up is Denver, really?”
“Find the route with the fewest traffic lights from Times Square to Central Park.”

Quick start
