Uses Flask to serve the web-based map interface and handle server-to-client communication
Provides a web-based map viewer interface for visualizing OpenStreetMap data
Enables querying and visualization of map data, with tools for map control including adding markers, polygons, setting views, and getting current view
Offers a query interface for OpenStreetMap data stored in PostgreSQL/PostGIS databases
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.
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
:
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

- Execute a SQL query against the OpenStreetMap database
This server cannot be installed
hybrid server
The server is able to function both locally and remotely, depending on the configuration or use case.
Provides OpenStreetMap integration for MCP, allowing users to query and visualize map data with tools for adding markers, polygons, and controlling the map view.
