name: qgis description: > Geospatial analysis and GIS operations via QGIS. Use for calculating distances, buffering zones, coordinate transforms (EPSG:4326 to EPSG:3857), layer operations, geoprocessing (intersect, union, clip), and exporting map images. Requires QGIS running on Display :1 with MCP plugin enabled. version: 2.0.0 author: turbo-flow-claude mcp_server: true protocol: fastmcp entry_point: mcp-server/server.py port: 9877 dependencies:

QGIS Skill

Geospatial analysis and GIS operations via FastMCP protocol, communicating with QGIS instance via TCP socket.

When to Use This Skill

• Calculate distances between geographic points
• Create buffer zones around features (proximity analysis)
• Transform coordinates between CRS (GPS to Web Mercator)
• Load and manipulate geospatial layers (Shapefile, GeoJSON, GeoPackage)
• Perform geoprocessing operations (intersect, union, difference, clip)
• Export map images for reports or web display
• Query features with spatial filters
• Style layers with categorized or graduated symbology

Tools

Examples

# Load a GeoJSON layer
load_layer({
    "path": "/data/cities.geojson",
    "name": "Cities"
})

# Create 10km buffer around points
buffer_analysis({
    "layer_name": "Cities",
    "distance": 10000,  # meters
    "output_name": "city_buffers"
})

# Transform GPS coordinates to Web Mercator
transform_coordinates({
    "coordinates": [-122.4194, 37.7749],  # San Francisco
    "source_crs": "EPSG:4326",
    "target_crs": "EPSG:3857"
})

# Export map image
export_map({
    "output_path": "/output/map.png",
    "width": 1920,
    "height": 1080,
    "dpi": 150
})

Environment Variables

Troubleshooting

Connection refused:

# Check QGIS is running on Display :1
supervisorctl status qgis

# Verify MCP plugin is loaded
# In QGIS: Plugins → Manage Plugins → Search "MCP"
