- Server: Godot (`@keeveeg/godot-mcp`) — https://policylayer.com/tools/keeveeg-godot-mcp.md
- Install: `npx -y @keeveeg/godot-mcp`
- Homepage: https://www.npmjs.com/package/@keeveeg/godot-mcp
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 2 (2 required)
- Recommended policy verdict: Rate-limited

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `path` | string | yes | Particle node path |
| `properties` | object | yes | Process material properties (direction, spread, gravity, initial_velocity, etc.) |

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_particle_material",
    "arguments": {
      "path": "<path>",
      "properties": {}
    }
  }
}
```

## Why set_particle_material is rated Medium

This tool creates or modifies particle material configurations in a Godot project, which is reversible through subsequent modifications or deletion. It does not execute arbitrary code, delete data irreversibly, or cause financial transactions. While it affects game rendering, the impact is localized to visual properties and can be easily undone.

From the tool's own definition: "Tool name 'set_particle_material' and description 'Set or create a ParticleProcessMaterial for a particle system' indicate creation or modification of particle system material properties."

Risk signals: Accepts file system path (path)

## Use case

AI agents use set_particle_material 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
{
  "version": "1",
  "default": "deny",
  "tools": {
    "set_particle_material": {
      "limits": [
        {

          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
