GeoGebra MCP server

This is a small helper that lets your AI draw geometry figures directly in GeoGebra Calculator, the free online drawing tool at geogebra.org. You ask for a figure, the AI builds it, checks it, and fixes its own mistakes. It is handy for teachers, students, and anyone who needs a clean geometry picture without clicking every point by hand.

What this MCP server does

You describe a figure in plain words, like a triangle with a circle around it. Your AI turns that into GeoGebra commands and sends them to this helper. The helper opens a Chrome or Edge window on GeoGebra Calculator and runs the commands there, one by one. It reads back any errors, the list of objects, and a screenshot, so the AI can spot mistakes and fix the figure. When it is done, you see the finished figure in the browser window and can drag or edit it by hand.

What you can do with it

• Draw points, lines, circles, and polygons from a plain description
• Check properties like angles, midpoints, and whether points are in a straight line
• Take a screenshot of the figure so the AI can see and correct it
• Change colors, labels, and line styles on any object
• Delete objects or start a fresh figure
• Undo changes and save named versions of a figure
• Export the figure as a GeoGebra file or a PNG image

Try asking your AI

• “Draw triangle ABC inside circle O, with height AH and M as the midpoint of BC.”
• “Check whether points A, H, and O lie on the same line.”
• “Make point H the foot of the perpendicular from A to BC.”
• “Color the circle blue, hide the axes, and take a screenshot.”

What it gives back to you

You get the figure itself, drawn live in the GeoGebra window on your screen. In the chat, the AI can also show you lists of objects, computed values like angles or coordinates, and short notes about any command that failed. It can save a picture or a GeoGebra file for you to keep. If something went wrong, it tells you what it tried and what it changed.
