Planetary Computer MCP Server

A Python implementation of the Planetary Computer MCP server, providing unified access to satellite and geospatial data through natural language queries.

Sample Outputs

Features

• Unified Interface: Single download_data tool that automatically detects datasets from natural language queries
• Natural Language Geocoding: Automatically converts place names (e.g., "San Francisco", "the Alps", "Amazon rainforest") to geospatial bounding box coordinates using the Nominatim geocoding service—no need to manually specify coordinates
• Multi-format Support: Raster (GeoTIFF), Vector (GeoParquet), and Zarr data
• Automatic Visualization: Generate RGB/JPEG previews for LLM analysis
• Fast Downloads: Uses odc-stac for efficient COG access

Installation

uv sync

Usage

As MCP Server

python -m planetary_computer_mcp.server

Direct API Usage

from planetary_computer_mcp.tools.download_data import download_data

# Download Sentinel-2 data for San Francisco
result = download_data(
    query="sentinel-2 imagery",
    aoi="San Francisco",
    time_range="2024-01-01/2024-01-31"
)

print(f"Raw data: {result['raw']}")
print(f"Visualization: {result['visualization']}")

Tools

download_data

Unified tool for raster, DEM, land cover, and climate data.

Parameters:

• query: Natural language query (e.g., "sentinel-2", "elevation data")
• aoi: Bounding box [W,S,E,N] or place name
• time_range: ISO8601 datetime range
• max_cloud_cover: Maximum cloud cover (optical data)

Returns:

• Raw GeoTIFF/Zarr/Parquet file
• RGB/JPEG visualization
• Metadata

download_geometries

Tool for vector/building data.

Parameters:

• collection: Collection ID (e.g., "ms-buildings")
• aoi: Bounding box or place name
• limit: Maximum features

Returns:

• GeoParquet file
• Map visualization
• Feature count

Supported Datasets

See collections.md for the complete list of supported datasets.
