Cesium MCP
The minimum-overhead way to add AI commands to CesiumJS
cesium-mcp-bridge is a protocol-agnostic command dispatcher with 60+ tools, drivable from browser-only agents, function calling, or MCP — your choice.
Three entry points: Browser Agent (simplest, zero backend) · function calling (embed in your web app) · MCP runtime (Claude Desktop / Cursor / Dify)
Try it now — open the live browser demo, no install, no signup.

Packages & Entry Points
| Module | Role | Status | Links |
|---|
| cesium-mcp-bridge | Protocol-agnostic command dispatcher (60+ tools) | Mainline, actively iterated |  · source |
| examples/browser-agent | Browser-only AI agent (recommended starting point, zero backend) | Recommended | example · live demo |
| cesium-mcp-runtime | MCP server (stdio + HTTP) | Stable, slow updates |  · source |
| cesium-mcp-dev | CesiumJS API knowledge base for coding assistants | Maintained |  · source |
Which one? Personal project or quick try → browser-agent. Existing web app embedding an AI assistant → bridge + your own function calling. Calling from Claude Desktop / Cursor / Dify → MCP runtime.

The bridge is the only required piece. Pick whichever driver matches your scenario — they all hit the same 60+ tools.
Quick Start
Path 0 — Try in 30 seconds (browser agent, recommended)
Open the live demo, paste an OpenAI-compatible API key, and ask:
"Fly to the Eiffel Tower and drop a red marker"
Fork the examples/browser-agent folder to deploy your own.
Path 1 — Embed in your own web app (function calling)
npm install cesium-mcp-bridge
import { CesiumBridge } from 'cesium-mcp-bridge';
