OpenStreetMap

The OSM PostgreSQL Server provides Claude with direct access to OpenStreetMap geospatial data stored in a PostgreSQL database with PostGIS extensions. Built by John Wiseman, this implementation allows querying complex geographic information including points of interest, roads, buildings, and natural features through SQL. The server includes comprehensive safety measures like read-only query enforcement and execution timeouts, while offering rich documentation through resources that explain OSM data structure, common query patterns, and spatial query techniques. It's particularly valuable for location-based analysis, finding geographic relationships between features, and extracting structured information about the physical world from the complete OpenStreetMap dataset.
