Reach for this when you need geospatial operations without standing up your own infrastructure. It wraps OpenStreetMap data into 18+ tools including geocoding (address to coordinates and reverse), routing between points, isochrone generation (travel time boundaries), H3 hexagonal indexing, and elevation lookups. The spread is practical: you can geocode user input, calculate driving distances, generate service area maps, or snap coordinates to H3 cells for spatial aggregation. All requests run through the MCP protocol via stdio, so you're querying OSM data without managing database dumps or tile servers yourself.
