OSM PostgreSQL Server

# MCP-OSM: OpenStreetMap Integration for MCP This package provides OpenStreetMap integration for MCP, allowing users to query and visualize map data through an MCP interface. [](osm-mcp.webp) ## Features - Web-based map viewer using Leaflet and OpenStreetMap - Server-to-client communication via Server-Sent Events (SSE) - MCP tools for map control (adding markers, polygons, setting view, getting view) - PostgreSQL/PostGIS query interface for OpenStreetMap data ## Installation This is my `claude_desktop_config.json`: ```json { "mcpServers": { "OSM PostgreSQL Server": { "command": "/Users/wiseman/.local/bin/uv", "args": [ "run", "--env-file", ".env", "--with", "mcp[cli]", "--with", "psycopg2", "--with-editable", "/Users/wiseman/src/mcp-osm", "--directory", "/Users/wiseman/src/mcp-osm", "mcp", "run", "mcp.py" ] } } } ``` When the MCP server starts it also starts a web server at http://localhost:8889/ that has the map interface. ### Environment Variables The following environment variables can be used to configure the MCP: - `FLASK_HOST` - Host for the Flask server (default: 127.0.0.1) - `FLASK_PORT` - Port for the Flask server (default: 8889) - `PGHOST` - PostgreSQL host (default: localhost) - `PGPORT` - PostgreSQL port (default: 5432) - `PGDB` - PostgreSQL database name (default: osm) - `PGUSER` - PostgreSQL username (default: postgres) - `PGPASSWORD` - PostgreSQL password (default: postgres) ### MCP Tools The following MCP tools are available: - `get_map_view` - Get the current map view - `set_map_view` - Set the map view to specific coordinates or bounds - `set_map_title` - Set the title displayed at the bottom right of the map - `add_map_marker` - Add a marker at specific coordinates - `add_map_line` - Add a line defined by a set of coordinates - `add_map_polygon` - Add a polygon defined by a set of coordinates - `query_osm_postgres` - Execute a SQL query against the OpenStreetMap database
