Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "geogebra": {
      "command": "npx",
      "args": [
        "-y",

        "GGB_HEADLESS": "your-value",
        "GGB_PROFILE_DIR": "your-value",
        "GGB_URL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add geogebra --env GGB_BROWSER=your-value --env GGB_HEADLESS=your-value --env GGB_PROFILE_DIR=your-value --env GGB_URL=your-value -- npx -y geogebra-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "geogebra": {
      "command": "npx",
      "args": [
        "-y",

    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "geogebra": {
      "type": "stdio",
      "command": "npx",
      "args": [

Common questions

Is Geogebra MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 19 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

geogebra-mcp

An MCP server that lets an AI (Claude Desktop, Claude Code, Cursor, …) draw and edit plane-geometry figures directly on GeoGebra® Calculator (https://www.geogebra.org/calculator).

Unlike the copy/paste workflow of the GeoGebra AutoDraw AI extension, the AI here works in a loop: it runs commands, reads errors and the figure state, verifies properties, looks at a screenshot, and fixes the figure itself — and it can edit the figure on request ("H must be the foot from A").

Made with GeoGebra® — https://www.geogebra.org

Unofficial project, not affiliated with or endorsed by GeoGebra GmbH. See License & GeoGebra.

How it works

AI client ──MCP (stdio)──► geogebra-mcp ──Playwright──► Chrome window: geogebra.org/calculator

└─ window.ggbApplet (GeoGebra JS API)

On the first tool call the server opens a Chrome (or Edge) window on GeoGebra Calculator. The user watches the figure being drawn and can drag/edit it by hand.
Tools call the GeoGebra JS API (ggbApplet) inside the page through page.evaluate — no simulated clicks.
Commands run through asyncEvalCommandGetLabels, which lazy-loads GeoGebra modules, so prover/scripting commands (AreCollinear, Incircle, TriangleCenter, ClosestPoint(line, point)…) work.
GeoGebra reports a failed command only as null, so the server adds its own diagnostics (unknown names, unknown commands, unbalanced brackets, known pitfalls) and warnings (undefined results, reserved names, two-point intersections without an index).
If the window is closed or reloaded, the next tool call reopens it and restores the last known figure.
Undo is managed by the server (XML history), because ggbApplet.undo() does not revert API commands.

Tools

Tool	Purpose
`ggb_run_commands`	Run commands in order; per-command result, created/removed objects, warnings, failure hints. Assigning to an existing name redefines it.
`ggb_get_state`	Objects with type, definition, value, coordinates, visibility, `dependsOn` / `usedBy`.
`ggb_screenshot`	PNG of the drawing area (or the whole window) for visual checking.
`ggb_evaluate`	Evaluate expressions without adding objects (`Angle(B, A, C)`, `AreCollinear(A, H, O)`…).
`ggb_set_style`	Color, visibility, label, caption, thickness, line style, point size, fill, fixed.
`ggb_delete`	Delete objects (and their dependents).
`ggb_clear`	Start a new figure.
`ggb_undo`	Revert changes made through the server.
`ggb_snapshot`	Save / restore / list named versions.
`ggb_fit_view`	Fit every visible point and circle in view (1:1 ratio), toggle axes/grid.
`ggb_export`	Save as `.ggb` or `.png`.

Also: resource geogebra://rules (construction rules), resource geogebra://commands (command catalog), prompt draw_geometry_problem.

Setup

Requirements: Node.js ≥ 20 and Google Chrome or Microsoft Edge (otherwise run npx playwright install chromium).

Claude Code (plugin)

claude plugin marketplace add haison8x/geogebra-mcp

claude plugin install geogebra-mcp@geogebra-tools

The server then shows up in /mcp as plugin:geogebra-mcp:geogebra. Update later with claude plugin update geogebra-mcp@geogebra-tools.

Claude Code (without the plugin)

claude mcp add geogebra -- npx -y geogebra-mcp

Claude Desktop, Cursor and other MCP clients

Edit claude_desktop_config.json (Settings → Developer → Edit Config), or your client's MCP config:

"mcpServers": { "geogebra": { "command": "npx", "args": ["-y", "geogebra-mcp"] } } }

Then restart the client and ask, for example: *"Vẽ tam giác ABC nội tiếp đường tròn (O), đường cao AH, M là trung điểm BC."*

From source

git clone https://github.com/haison8x/geogebra-mcp.git

cd geogebra-mcp npm install npm run build claude mcp add geogebra -- node /path/to/geogebra-mcp/dist/index.js

Configuration (environment variables)

Variable	Default	Meaning
`GGB_BROWSER`	try `chrome`, `msedge`, then Playwright Chromium	Browser channel
`GGB_HEADLESS`	`0`	`1` to run without a window (testing)
`GGB_PROFILE_DIR`	`~/.geogebra-mcp/profile`	Browser profile (keeps the GeoGebra login). One server instance per profile.
`GGB_URL`	`https://www.geogebra.org/calculator`	Page to open

Development

Releasing: bump the version in package.json, .claude-plugin/plugin.json, .claude-plugin/marketplace.json, server.json (both version fields) and the pinned version in .mcp.json. Then push, npm publish, mcp-publisher publish, and create a GitHub release.

npm run build

npm run smoke # end-to-end test through a real MCP client (headless) npm run smoke -- --headed # same, with a visible window

Notes

Snapshots and undo history live in memory while the server runs.
