- Parameters: 3 (2 required)
- Recommended policy verdict: Rate-limited

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `path` | string | yes | AnimationTree node path |
| `value` | object | no | Parameter value |
| `parameter` | string | yes | Parameter path (e.g. 'parameters/blend_position') |

Parameters from the server's own tool schema.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "set_tree_parameter",
    "arguments": {
      "path": "<path>",
      "parameter": "<parameter>"
    }
  }
}
```

## Why set_tree_parameter is rated Medium

This tool modifies AnimationTree parameters, which is a write operation that changes application state. While it affects gameplay/animation behavior, the change is reversible (parameters can be adjusted back or reset), and it does not execute arbitrary code, delete data, or cause financial impact.

From the tool's own definition: "The tool 'set_tree_parameter' performs parameter modification on an AnimationTree node, changing properties like 'blend amount' and 'state'. This is a reversible data modification operation within a game engine context."

Risk signals: Accepts file system path (path)

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
