[Website & Live Interactive Demo](https://eo-mcp.github.io/) • [LinkedIn Page](https://www.linkedin.com/company/eo-mcp/) • [Quickstart](#quickstart) • [Tools Reference](#tools-reference) • [Architecture](#architecture) <img src="assets/hero-earth.gif" alt="eo-mcp : Autonomous Planetary Earth Observation Protocol" width="720" style="max-width: 100%; border-radius: 8px;" /> </div> --- ## Why `eo-mcp`? Proprietary platforms (like Planet Labs' agentic dashboard or Google Earth Engine) build walled gardens that trap users in closed user interfaces and expensive recurring subscription paywalls. `eo-mcp` takes the opposite philosophy, modeled after open-source community standards: - **100% Open Standards**: Speaks standard **Model Context Protocol (JSON-RPC 2.0)**. Works in Claude Desktop, Cursor IDE, VS Code, Open WebUI, and custom agent frameworks (LangChain, AutoGen, CrewAI). - **Zero-Config Free Government Data**: Instant out-of-the-box queries to AWS Earth Search, NASA CMR, and Copernicus public STAC endpoints for Sentinel-2, Landsat 8/9, and Copernicus DEM without needing API keys. - **Cloud-Native COG Streaming**: Never download a 1GB satellite granule again. `eo-mcp` leverages HTTP range requests (`/vsicurl/`) to stream and compute band math on only the exact bounding box of your city, farm, or river in seconds (saving >98% bandwidth). - **Deterministic Scientific Visualization (Zero AI Hallucinations)**: 100% script-driven visual outputs (NumPy arrays, 256-color scientific LUT rasters, GeoJSON vectors, georeferenced GeoTIFFs, and self-contained interactive Leaflet web maps) computed directly from real satellite pixels and coordinates. Generative AI imagery tools (Midjourney, DALL-E, Nano Banana) are strictly prohibited. - **Autonomous Agentic Script Runner**: When standard tools aren't enough, agents can generate and run custom `rasterio`, `xarray`, and `geopandas` scripts inside an isolated geospatial sandbox. --- ## Quickstart > [!IMPORTANT] > **100% Free & Zero-Config:** You **DO NOT** need a Copernicus API key, ESA account, or paid subscription. Baseline satellite streams (Sentinel-2, Landsat, and Copernicus DEM) stream directly from open government cloud archives out-of-the-box. ### 0.

Eliminates 4–6 round trips and prevents LLM chaining errors. 2. **Category Scoping & Lean Context Windows**: Scope tools via `EO_MCP_PROFILE` or `--profile` (`workflows`, `hazards`, `climate`, `maritime`, `minimal`) to reduce prompt bloat by up to 70%. 3. **Progressive Tool Discovery**: Clients dynamically search and inspect tools via `discover_eo_tools`. 4. **Code Mode Ergonomics**: Pythonic imports (`from eo_mcp import assess_location_hazard, environmental_site_audit`) allow autonomous agents in code execution sandboxes to run multi-step pipelines directly with zero JSON-RPC overhead. --- ### 🌟 Ergonomic Workflow Tools (High-Level Turnkey Operations) #### 1. `assess_location_hazard(location: str, hazard_type: str, ...)` **All-in-one disaster & climate hazard assessment.** Accepts a natural language place name (`"Valencia, Spain"`, `"Rhodes, Greece"`) or bounding box.

Execute custom user-defined JSON pipeline specification eo-mcp pipeline run --spec my_pipeline.json --location "Venice, Italy" --format summary ``` --- ## Cloud-Native COG Streaming (How it works) Traditional GIS downloads entire satellite scenes (often 800MB to 1.5GB) before clipping to the study area. When interacting with an AI agent over the internet, downloading gigabytes of data per query creates latency and exhausts disk space. `eo-mcp` uses **Cloud Optimized GeoTIFF (COG)** range streaming: 1. The server reads the COG header over HTTP (~10KB) to discover internal tile offsets and coordinate projection. 2. It translates the user's bounding box into pixel window coordinates. 3. It performs targeted HTTP `Range: bytes=...` requests to pull **only the pixels covering the bounding box**. 4. A typical query transfers **2 MB to 5 MB** of data and completes in under 2 seconds. --- ## Flexible Credential Management `eo-mcp` is designed with a **zero-friction, open-first philosophy**: 1. **Zero-Config Default (100% Free)**: Out of the box, `eo-mcp` streams satellite data from free open government cloud archives (AWS Earth Search, NASA CMR, Copernicus public STAC). No user registration, API keys, or credit cards are needed. 2. **First-Class Support for User Credentials**: When users or enterprise agents need to access authenticated or proprietary features (such as direct Copernicus CDSE full-granule downloads, NASA Earthdata restricted collections, or Microsoft Planetary Computer signed tokens), credentials can be provided at any time: - **Environment Variables (`.env`)**: ```bash export CDSE_USERNAME="your-cdse-email" export CDSE_PASSWORD="your-cdse-password" export EARTHDATA_TOKEN="your-nasa-token" export PC_SDK_SUBSCRIPTION_KEY="your-pc-key" export FIRMS_MAP_KEY="your-firms-key" ``` - **In-Session Dynamic Tool (`configure_credentials`)**: AI agents can invoke `configure_credentials(provider="cdse", username="...", password="...")` dynamically during the conversation without restarting the server. - **CLI Credential Command**: ```bash eo-mcp auth set --provider cdse --username "user@example.com" --password "secret" eo-mcp auth ``` --- ## Scientific Foundation & Literature All algorithms, spectral indices, radar clutter models, and environmental hazard metrics in `eo-mcp` are strictly grounded in canonical peer-reviewed scientific literature, geodetic standards, and European space policy frameworks (such as the EU Floods Directive 2007/60/EC, Marine Strategy Framework Directive MSFD Descriptor 8, and EU Climate Adaptation Strategy).
