cesium-mcp-dev — Claude Code MCP server: features and setup
This MCP server gives coding assistants tools to look up CesiumJS APIs, generate code, and build Entity configurations. Use it while developing CesiumJS projects.
claude mcp add cesium-mcp-dev -- npx -y cesium-mcp-devWhat cesium-mcp-dev does
The server exposes three tools: API reference lookup, code generation from a natural-language request, and an interactive Entity configuration builder. Look up a class, method, or property to retrieve reference details. The generator covers tasks such as loading GeoJSON or 3D Tiles and adding map features; the builder accepts types including polygons, models, and polylines.
It communicates over MCP stdio and runs with npx -y cesium-mcp-dev. In Claude Code, add it with the command in the FAQ. The listed pairing for server version 1.145.x is Cesium around 1.145.0. Usage statistics are enabled by default, so disable them with CESIUM_TELEMETRY_DISABLED=1, DO_NOT_TRACK=1, or --no-telemetry if you don’t want them collected.
What it helps with
- look up methods and properties in the Cesium API
- generate TypeScript snippets from a task description
- build an Entity configuration with chosen properties
- create code for loading GeoJSON or 3D Tiles
Example prompts for the agent
- Look up the
Cesium3DTilesetAPI and show how to load one. - Write TypeScript code to add a marker to my CesiumJS map.
- Build a polygon Entity with color
