Bbox Mcp Server

Ask AI about anything, anywhere — and verify the answer on a map. For Free

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 tovibhorsingh.com/boundingbox— click it to visually confirm results on an interactive map. No other MCP server does this.

{ "mcpServers": { "bbox": { "command": "npx", "args": ["-y", "bbox-mcp-server"] } } }

{ "mcpServers": { "bbox": { "command": "npx", "args": ["-y", "bbox-mcp-server"] } } }

Add to~/.codeium/windsurf/mcp_config.json:

{ "mcpServers": { "bbox": { "command": "npx", "args": ["-y", "bbox-mcp-server"] } } }

Add to.vscode/mcp.jsonin your workspace:

{ "servers": { "bbox": { "command": "npx", "args": ["-y", "bbox-mcp-server"] } } }

Try:"Find all coffee shops within 500m of Times Square"

{ "mcpServers": { "bbox": { "command": "npx", "args": ["-y", "bbox-mcp-server"], "env": { "MAPBOX_ACCESS_TOKEN": "pk.your-token-here", "OVERPASS_API_URL": "https://your.custom.overpass.instance/api/interpreter", "NOMINATIM_API_URL": "https://your.custom.nominatim.instance" } } } }

Or install globally:npm install -g bbox-mcp-server

Convert and project a bounding box across 6 input formats, 9 output formats, and 3,900+ coordinate systems. Returns the center point and tile coordinates for the centroid.

💡 Prompt:"Get the bounding box for Central Park in WKT format projected to EPSG:32618"

Generate Uber H3 hexagonal cell indices covering a bounding box.

💡 Prompt:"Give me H3 cells at resolution 7 for downtown Chicago, include the hex geometries"

Execute an Overpass query within a bounding box or radius. Returns structured results with names, coordinates, and tags. The verification link plots each result as a pin on the map.

💡 Prompt:"Find all parking within 2km of JFK airport"

💡 Prompt:"Search for hospitals in Manhattan, limit 50"

Look up the correct OpenStreetMap tags for a category before writing an Overpass query.

💡 Prompt:"What are the correct OSM tags for supermarkets?"

Run an Overpass query and bin results into H3 hexagons for spatial density analysis. Returns counts per cell and GeoJSON hex boundaries.

💡 Prompt:"Aggregate all hospitals in Seattle into H3 bins at resolution 7"

Generate a shareable link to visualize a bounding box on the interactive map at vibhorsingh.com/boundingbox.

💡 Prompt:"Generate a share link for bbox 40.7128,-74.0060,40.7580,-73.9855"

All tools auto-detect the input format. No need to specify which one you're using.
- Human-readable text— formatted output with the map verification link
- Structured JSON— all computed data, machine-parseable

All errors returnisError: truewith a descriptive message. Invalid coordinates, unknown EPSG codes, and oversized H3 requests all return clean errors — the server never crashes on bad input.

Structured JSON logs go tostderr(stdout is reserved for MCP protocol). Each entry includes timestamp, level, and context.

This tool is built onOpenStreetMap: A global dataset created and maintained by millions of volunteers. Every query you run returns data that someone walked, mapped, or verified by hand. If you find this useful, considercontributing to OSM.

The public Overpass and Nominatim API instances are free community resources with limited capacity. Avoid tight loops, excessive polling, or bulk-scraping. If hosting this as a shared/remote MCP server, pointNOMINATIM_API_URLandOVERPASS_API_URLat your own instance or a commercial provider (seeOverpass API installationandNominatim installation). The default server rotation for Overpass helps spread load, but it's not a substitute for responsible usage.
