Cesium 3D Globe MCP server

This is a helper that connects your AI assistant to a 3D globe viewer built with CesiumJS. Once it is set up, you can just describe what you want to see on the globe, and the AI moves the camera, drops markers, and loads map data for you. It is handy for anyone who works with maps, locations, or 3D scenes and would rather type a request than click around a map tool.

What this MCP server does

You type a request in plain words, like flying somewhere or adding a marker. Your AI reads that request and picks the right action from this helper, such as moving the camera or loading a data layer. The helper then talks to the Cesium globe and makes the change. The globe updates in front of you, and the AI tells you what it did. You can keep asking for more changes in the same conversation.

What you can do with it

• Fly the camera to a place, a set of coordinates, or a saved viewpoint
• Drop markers, labels, and simple 3D shapes on the globe
• Load map layers from GeoJSON, 3D Tiles, KML, or CZML files
• Measure distances and highlight things on the map
• Take a screenshot of the current globe view
• Show a heatmap of points on the map
• Play a moving path or trajectory over time

Try asking your AI

• “Fly to the Eiffel Tower and drop a red marker there”
• “Load this GeoJSON file as a layer and make the outlines blue”
• “Take a screenshot of the current view and save it”
• “Show a heatmap of these city locations”
• “Measure the distance between these two points on the globe”

What it gives back to you

You get answers in the chat plus changes on the globe itself. The AI may reply with a short summary, a list of layers or markers, or numbers like a measured distance. It can also hand back a screenshot image of the current view. Anything it adds or moves shows up right away in the Cesium viewer.
