How to Set Up and Use Cesium
Cesium MCP connects any MCP-compatible AI agent to a CesiumJS 3D globe running in a web browser, enabling natural language control of geospatial visualization. Through the server's 58 tools across 12 toolsets, an AI can fly the camera to any location, add markers, labels, 3D models, polygons, and polylines, load GeoJSON layers, take screenshots, and measure distances — all by responding to plain English commands. It is designed for GIS developers, geospatial analysts, and data visualization teams who want to drive CesiumJS interactively without writing JavaScript manually.
Prerequisites
- Node.js 18+ and npx available on your machine
- A CesiumJS application running in a web browser (use the provided demo or your own app)
- The cesium-mcp-bridge npm package installed in your CesiumJS app to receive commands
- An MCP-compatible client such as Claude Desktop, Cursor, or VS Code with MCP support
- Optional: a Cesium ion account and access token for terrain and imagery layers
Install the cesium-mcp-bridge in your CesiumJS app
Add the bridge package to your CesiumJS web application so it can receive commands from the MCP server.
npm install cesium-mcp-bridgeTry the live demo first
Before setting up locally, try the live browser demo at the official demo URL to verify the concept works with your MCP client.
# Open in your browser:
# https://cesium-browser-agent.pages.dev/Configure your MCP client to use cesium-mcp-runtime
Add the cesium-mcp-runtime server to your Claude Desktop or Cursor configuration. By default, 4 core toolsets with ~31 tools are enabled.
Enable all 12 toolsets (optional)
To unlock all 58 tools including camera animation, heatmaps, trajectory visualization, and geolocation, set the CESIUM_TOOLSETS environment variable.
# In your MCP config env block, add:
# "CESIUM_TOOLSETS": "all"Start the MCP server in HTTP mode for web integration
For integration with web-based CesiumJS apps, run the server in HTTP mode on a specified port.
npx cesium-mcp-runtime --transport http --port 3000Verify the connection
Ask your AI client to fly to a known location to confirm the server is controlling the 3D globe.

Example prompts to control the CesiumJS 3D globe through your AI client.
- "Fly to the Eiffel Tower and drop a red marker labeled 'Eiffel Tower'."
- "Load the GeoJSON file at /data/countries.geojson as a new layer and set its visibility to true."
- "Show me all currently loaded layers and toggle off the terrain layer."
- "Zoom to the extent of the United States and take a screenshot."
- "Add a polyline connecting New York, London, and Tokyo and measure the total distance."Troubleshooting Cesium
AI commands do not move the globe in the browser
Ensure the cesium-mcp-bridge package is installed and initialized in your CesiumJS application. The bridge must be imported and connected to the same server port that cesium-mcp-runtime is using. Check the browser console for WebSocket connection errors.
Only 31 tools are available instead of 58
By default only 4 core toolsets are enabled. Set CESIUM_TOOLSETS=all in the env block of your MCP configuration to enable all 12 toolsets with the full 58 tools, then restart the server.
Terrain or imagery layers fail to load
Cesium ion terrain and imagery assets require a valid Cesium ion access token. Set your token in the CesiumJS application with `Cesium.Ion.defaultAccessToken = 'your-token'`. Get a free token at cesium.com/ion.
