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:

{
  "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.

How do I install Osm MCP?

No package has been published for this server, so install it from source: clone the repository and follow its README.

Is Osm MCP safe to use with an AI agent?

Its trust score is 46 out of 100 (fair). It passes 3 of the 6 static security checks run so far; the failures are listed above. It has no ConduID identity yet, so agent calls to it are not receipted.

Is Osm MCP still maintained?

The last commit was a year ago and 5 open issues. That's long enough that you should check whether the maintainer is responding to issues before depending on it.
