What is Gdal Mcp?
Gdal Mcp is a Model Context Protocol server that gives AI agents geospatial analysis capabilities backed by GDAL, Rasterio, and PyProj. It requires AI agents to justify methodological choices—such as CRS selection or resampling—through a reflection middleware system, creating an auditable trail of epistemic reasoning. It is designed for developers and geospatial professionals who want reproducible, methodology-aware geospatial workflows with AI.
How to use Gdal Mcp?
Install via uvx --from gdal-mcp gdal --transport stdio or run with Docker. Configure the server in your MCP client (e.g., Claude Desktop) by adding a gdal-mcp entry to mcpServers with the uvx command and setting the GDAL_MCP_WORKSPACES environment variable. The server exposes 12 tools: 4 raster tools (info, convert, reproject, stats) and 6 vector tools (info, reproject, convert, clip, buffer, simplify), plus reflection system tools.
Key features of Gdal Mcp
- Reflection middleware forces methodological justification before execution.
- Structured justifications capture intent, alternatives, tradeoffs, and confidence.
- Persistent cache achieves 75% hit rates across raster–vector workflows.
- 12 production-ready tools for raster and vector operations.
- Workspace isolation and path validation for security.
- Python-native stack (Rasterio, PyProj, pyogrio, Shapely, NumPy).
Use cases of Gdal Mcp
- Reprojecting a DEM to UTM for accurate slope analysis with documented CRS reasoning.
- Overlaying vector and raster datasets after justifying a common projection.
- Converting file formats (GeoTIFF, COG, Shapefile, GeoJSON, GPKG) while recording methodological tradeoffs.
- Clipping or buffering vector layers for spatial subsetting with an audit trail.
- Educational scenarios where AI learns geospatial best practices through required justification.
