mcp-geo

A geospatial MCP server that gives agents dependable GIS tools: geocoding, routing, OpenStreetMap queries, geometry operations, file inspection, raster sampling, elevation, isochrones, static maps, and workspace storage.

Why it exists

Geospatial work usually requires several specialized libraries and services. mcp-geo packages common GIS operations behind stable MCP tools so an agent can compose real spatial workflows instead of generating one-off scripts.

Example workflow:

1. geocode a place such as "Buriganga River, Dhaka".
2. buffer the returned point by 2 km.
3. osm_features for {"amenity": "hospital"} inside that area.
4. distance or nearest_neighbor to rank the results.
5. static_map or save_map to create a visual preview.

Installation

pip install mcp-geo

For local GIS files:

pip install "mcp-geo[files,raster,visual]"

MCP client config

{
  "mcpServers": {
    "geo": {
      "command": "uvx",
      "args": ["mcp-geo"]
    }
  }
}

The default transport is stdio. HTTP and SSE are also available:

mcp-geo --http --host 127.0.0.1 --port 8000
mcp-geo --sse --host 127.0.0.1 --port 8000

Tools

Geometry

Configuration

The server works without configuration by using public geospatial services. For production use, self-host high-volume providers where possible.

mcp-geo sends a project-specific User-Agent and rate-limits Nominatim calls to one request per second by default.

Development

git clone https://github.com/tabibhasann/geo-mcp.git
cd geo-mcp
uv sync --group dev
uv run ruff check src/ tests/
uv run mypy src/
uv run pytest

Optional GIS dependencies can be tested with:

uv sync --group dev --extra files --extra raster --extra visual
uv run pytest

Docker

docker build -t mcp-geo .
docker run --rm -p 8000:8000 mcp-geo mcp-geo --http --host 0.0.0.0 --port 8000
