- Homepage: https://github.com/EaseHee/rhino-mcp

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

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

## Why gh_set_toggle is rated Medium

This tool creates or modifies component state within Grasshopper (a visual programming environment in Rhino). Setting a toggle affects downstream geometry generation and manipulation workflows. While reversible (can toggle back), it alters parametric design state and could trigger unintended geometry creation or modifications depending on what the toggle controls.

From the tool's own definition: "Tool description states 'Set a Boolean Toggle component' — explicitly sets/modifies state of a Grasshopper component to a Boolean value (true or false)."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
