Overview

AI-generated overview

Local MCP server that gives IDE AI assistants CesiumJS API documentation lookup, code snippet generation and Entity configuration building.

What you can do
  • Look up Cesium API documentation by class name, method or property, covering 12 classes such as Viewer, Entity, Camera and Cesium3DTileset.
  • Generate Cesium code from natural language descriptions for 11 built-in scenarios, including fly-to, markers, GeoJSON loading, polylines, polygons, 3D Tiles and heatmaps.
  • Build Entity configurations for 8 types (point, billboard, label, polyline, polygon, model, ellipse, box) with material, style and ground clamping.
When to use it
Useful when you write CesiumJS 3D globe or geospatial code in an IDE assistant such as VS Code Copilot, Cursor or Claude Desktop and want API references and ready-to-use snippets instead of guessing at the API.
Requirements
Runs as a local stdio process, typically started with npx, so Node.js and network access for the package download are needed. No authentication, environment variables or headers are declared.
Before you install
Usage statistics are collected by default; disable them with CESIUM_TELEMETRY_DISABLED=1, DO_NOT_TRACK=1 or the --no-telemetry flag. The README states the server targets Cesium ~1.145.0, so documentation may lag other versions.

Installation

In SourceWeft

  1. Open Cesium Mcp Dev in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Usage statistics are on by default, with a startup notice on stderr. Set CESIUM_TELEMETRY_DISABLED=1, DO_NOT_TRACK=1, or pass --no-telemetry to disable. Collected fields and privacy.

MCP Server for IDE AI assistants -- Cesium API documentation, code generation, and Entity builder.

[npm version] [license]

What is this?

cesium-mcp-dev helps AI coding assistants (GitHub Copilot, Cursor, Claude Code, etc.) write better CesiumJS code by providing API documentation lookup, code snippet generation, and Entity configuration building -- all through the MCP protocol.

The stable stdio server uses MCP SDK v2 and negotiates both MCP 2025-11-25 and 2026-07-28 clients.

npx -y cesium-mcp-dev

IDE Configuration

VS Code (Copilot)

In .vscode/mcp.json:

json
{  "servers": {    "cesium-dev": {      "command": "npx",      "args": ["cesium-mcp-dev"]    }  }}

Cursor

In .cursor/mcp.json:

json
{  "mcpServers": {    "cesium-dev": {      "command": "npx",      "args": ["cesium-mcp-dev"]    }  }}

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

MCP Tools (3)

cesium_api_lookup

Query Cesium API documentation by class name, method, or property.

Input: "Viewer"Output: Constructor signature, properties, methods, and usage examples

Covered classes: Viewer, Entity, Camera, Cartesian3, Color, GeoJsonDataSource, ImageryLayer, Cesium3DTileset, Material, ScreenSpaceEventHandler, flyTo, setView (12 classes)

cesium_code_gen

Generate Cesium code from natural language descriptions.

Input: "Add a red point marker at Tiananmen Square"Output: Complete TypeScript code snippet ready to use

Built-in snippets: fly to location, add marker, load GeoJSON, draw polyline, draw polygon, load 3D Tiles, switch basemap, click handler, screenshot, heatmap, trajectory animation (11 scenarios)

cesium_entity_builder

Build Entity configurations interactively by specifying type and properties.

Input: type: "polygon", position: {lon: 116.4, lat: 39.9}, color: "#ff6600"Output: Complete Entity definition with material, style, and ground clamping

Supported types: point, billboard, label, polyline, polygon, model, ellipse, box (8 types)

Example Interactions

AI assistant asks: "How do I load a 3D Tiles model from Cesium Ion?"

The assistant calls cesium_api_lookup with "Cesium3DTileset", gets the API reference, then calls cesium_code_gen with the user's specific requirements to generate ready-to-use code.

AI assistant asks: "Create an Entity for a semi-transparent blue polygon"

The assistant calls cesium_entity_builder with type: "polygon", color: "#0066ff", opacity: 0.5 and gets complete code output.
