## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "geogebra_export_png",
    "arguments": {}
  }

```

## Why geogebra_export_png is rated Medium

Exporting a view to PNG creates a new file artifact but does not modify the underlying GeoGebra construction itself, nor does it irreversibly delete or execute arbitrary code. This is a reversible write operation—generating output data. Severity is low because creating an image export has minimal blast radius and no permanent side effects on the model or system.

From the tool's own definition: "Tool name 'geogebra_export_png' and description indicate exporting/saving the current GeoGebra view as a PNG screenshot, which creates a new file output."

## Use case

AI agents use geogebra_export_png to create or update resources in GeoGebra MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GeoGebra MCP Server environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches GeoGebra MCP Server:
