Quick Start

1. Install the bridge in your CesiumJS app

npm install cesium-mcp-bridge

import { CesiumBridge } from 'cesium-mcp-bridge';

const bridge = new CesiumBridge(viewer);

2. Start the MCP runtime

# stdio mode (default — for Claude Desktop, VS Code, Cursor)
npx cesium-mcp-runtime

# HTTP mode (for Dify, remote/cloud MCP clients)
npx cesium-mcp-runtime --transport http --port 3000

3. Connect your AI agent

Add to your MCP client config (e.g. Claude Desktop):

{
  "mcpServers": {
    "cesium": {
      "command": "npx",
      "args": ["-y", "cesium-mcp-runtime"]
    }
  }
}

Now ask your AI: "Fly to the Eiffel Tower and add a red marker"

58 Available Tools

Tools are organized into 12 toolsets. Default mode enables 4 core toolsets (~31 tools). Set CESIUM_TOOLSETS=all for everything, or let the AI discover and activate toolsets dynamically at runtime.

i18n: Tool descriptions default to English. Set CESIUM_LOCALE=zh-CN for Chinese.

Toolset Tools
view (default) flyTo, setView, getView, zoomToExtent, saveViewpoint, loadViewpoint, listViewpoints, exportScene
entity (default) addMarker, addLabel, addModel, addPolygon, addPolyline, updateEntity, removeEntity, batchAddEntities, queryEntities, getEntityProperties
layer (default) addGeoJsonLayer, listLayers, removeLayer, clearAll, setLayerVisibility, updateLayerStyle, getLayerSchema, setBasemap
interaction (default) screenshot, highlight, measure
camera lookAtTransform, startOrbit, stopOrbit, setCameraOptions
entity-ext addBillboard, addBox, addCorridor, addCylinder, addEllipse, addRectangle, addWall
animation createAnimation, controlAnimation, removeAnimation, listAnimations, updateAnimationPath, trackEntity, controlClock, setGlobeLighting
tiles load3dTiles, loadTerrain, loadImageryService, loadCzml, loadKml
trajectory playTrajectory
heatmap addHeatmap
scene setSceneOptions, setPostProcess
geolocation geocode

Relationship with CesiumGS official MCP servers: The camera, entity-ext, and animation toolsets natively fuse capabilities from CesiumGS/cesium-mcp-server (Camera Server, Entity Server, Animation Server) into this project's unified bridge architecture. This means you get all official functionality plus additional tools — in a single MCP server, without running multiple processes.

Segment Meaning Example
1.139 Tracks CesiumJS version — built & tested against Cesium ~1.139.0 1.139.8 → Cesium 1.139
.8 MCP patch — independent iterations for new tools, bug fixes, docs 1.139.7 → 1.139.8

When CesiumJS releases a new minor version (e.g. 1.140), we will bump accordingly: 1.140.0.
