This server does not currently have a deployable release on Glama. Follow the repository's setup instructions to install and configure it for your MCP client, including any required credentials and local dependencies.
MCP server for interactive glacier mapping.
Renders a GeoTIFF in OpenLayers, lets you draw and edit polygons with the mouse, and exposes every vertex to an AI agent via MCP tools (get / move / add / delete). Exports the final geometry to a shapefile with a correct .prj.
Existing GIS tools (ArcGIS Pro, QGIS) can be automated via MCP, but none of them give an AI agent direct, per-vertex control over geometry while you edit the same geometry with your mouse. This project fills that gap: the map and the agent share the same polygon state.

| OpenLayers UI | <----------------> | FastAPI backend | <----------> | Agent |
| (your mouse) | | (state + geom) | | (LLM) |
+----------------+ +-------------------+ +-------+Backend: Python 3.11, FastAPI, mcp SDK, uvicorn, shapely, pyproj.
Frontend: OpenLayers 10, vanilla JS.
I/O: rasterio (GeoTIFF), geopandas (shapefile).
Bridge: WebSocket (frontend <-> backend), MCP streamable-http (agent <-> backend).
Two ports, one process:
http://localhost:8765 - interactive map (open in browser)
http://localhost:8766 - MCP endpoint (connect your MCP client here)
Both share one PolygonState instance, so a vertex moved by the agent appears in the browser and vice versa.
pip install -r requirements.txt
python -m glacier_mcpThen:
Draw a polygon with the mouse (OpenLayers Draw interaction)
Drag a vertex (OpenLayers Modify interaction)
Connect your MCP client (Claude Desktop / Cursor / DeepSeek++ / etc.) to http://localhost:8766
Ask the agent: "move the western boundary 50 meters east"
The polygon in the browser updates as the agent edits.
