## MCP tools (11)

### `ggb_run_commands` (~164 tokens)

Run GeoGebra commands

Run GeoGebra commands on the live figure, in order (English command names, e.g. "A = (-1, 6)", "M = Midpoint(B, C)", "ShowLabel(a, false)", "SetVisibleInView(h, 1, false)", "Delete(P)"). Assigning to an existing name REDEFINES that object and its dependents update. Returns, per command: ok, created/removed objects, warnings (undefined objects, names not created) and, for failures, hints about the likely cause.

Input parameters:

- `commands` (array, required): Commands to run, one per item, in execution order
- `stop_on_error` (boolean): Stop at the first failed command (later commands usually depend on it). Default true.

### `ggb_get_state` (~93 tokens)

Read the figure

List the objects currently in the figure: name, type, definition, value, point coordinates, visibility, dependsOn (parents) and usedBy (objects that would change or be deleted with it). Always call this before fixing a figure: the user may have edited it by hand.

Input parameters:

- `include_hidden` (boolean): Include hidden helper objects. Default true.
- `names` (array): Only return these objects

### `ggb_screenshot` (~61 tokens)

Screenshot the figure

Return a PNG image of the drawing area so you can check the figure visually (overlapping labels, figure off-screen, wrong shape). Set full_window to capture the whole GeoGebra window including the algebra panel.

Input parameters:

- `full_window` (boolean)

### `ggb_evaluate` (~92 tokens)

Evaluate expressions

Evaluate GeoGebra expressions against the current figure WITHOUT adding objects, to verify the construction. Examples: "Angle(B, A, C)", "Distance(B, M) == Distance(M, C)", "AreCollinear(A, H, O)", "AreParallel(Line(A, D), Line(B, C))", "Radius(omega)", "Area(poly1)".

Input parameters:

- `expressions` (array, required)

### `ggb_set_style` (~157 tokens)

Style objects

Change how objects look: color, visibility, label, caption (text shown instead of the name), thickness, line style, point size, fill, fixed.

Input parameters:

- `caption` (string): Text shown as the label; empty string restores the name
- `color` (string): Hex color, e.g. "#d32f2f"
- `filling` (number): Fill opacity 0..1 for polygons and circles
- `fixed` (boolean): Prevent the user from dragging the object
- `label_visible` (boolean)
- `line_style` (string)
- `line_thickness` (integer)
- `names` (array, required)
- `point_size` (integer)
- `visible` (boolean)

### `ggb_delete` (~53 tokens)

Delete objects

Delete objects. WARNING: everything that depends on them is deleted too (see usedBy in ggb_get_state). To change an object, redefine it with ggb_run_commands instead.

Input parameters:

- `names` (array, required)

### `ggb_clear` (~27 tokens)

Clear the figure

Remove every object to start a new figure (can be reverted with ggb_undo).

### `ggb_undo` (~42 tokens)

Undo

Revert the last change(s) made through this server (run_commands, set_style, delete, clear, snapshot restore).

Input parameters:

- `steps` (integer)

### `ggb_snapshot` (~49 tokens)

Save / restore a version

Save the current figure under a name, restore a saved one, or list saved names. Snapshots live while the server runs.

Input parameters:

- `action` (string, required)
- `name` (string)

### `ggb_fit_view` (~71 tokens)

Fit the view

Zoom/pan so every visible point and circle fits in the drawing area (1:1 axis ratio). Optionally show/hide axes and grid.

Input parameters:

- `padding` (number): Margin as a fraction of the figure size
- `show_axes` (boolean)
- `show_grid` (boolean)

### `ggb_export` (~63 tokens)

Export the figure

Save the figure to a local file: "ggb" (GeoGebra file, can be opened again in GeoGebra) or "png" (image).

Input parameters:

- `format` (string, required)
- `path` (string, required): Destination file path on this computer

## Common questions

### What is the io.github.haison8x/geogebra-mcp server?

io.github.haison8x/geogebra-mcp is listed in the public MCP registry as io.github.haison8x/geogebra-mcp. Draw and edit geometry live on GeoGebra Calculator. Unofficial, not affiliated with GeoGebra. This page covers its npm package (geogebra-mcp).

### Is the io.github.haison8x/geogebra-mcp server safe to use?

io.github.haison8x/geogebra-mcp scores 78 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the io.github.haison8x/geogebra-mcp server expose?

io.github.haison8x/geogebra-mcp exposes 11 tools: ggb_run_commands, ggb_get_state, ggb_screenshot, ggb_evaluate, ggb_set_style, and 6 more. Their descriptions and schemas cost roughly 872 tokens of context every time the server is loaded.

### Is the io.github.haison8x/geogebra-mcp server still maintained?

io.github.haison8x/geogebra-mcp is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the io.github.haison8x/geogebra-mcp server under?

io.github.haison8x/geogebra-mcp declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
