- Homepage: https://github.com/jlivingston-Cipher/godot-breakpoint-mcp
- Risk category: Write (Medium risk)

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

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

## Why shadermaterial_create is rated Medium

This tool creates a new shader material object and modifies node properties by assigning it, which are reversible write operations. It does not execute arbitrary code, delete data, or move resources. The medium severity reflects that misuse could alter scene appearance or introduce unintended visual effects, but changes remain reversible through reassignment or deletion.

From the tool's own definition: "Tool description states 'Create a ShaderMaterial and assign it to a node' — the verb 'create' and 'assign' indicate data creation and modification within the Godot scene tree."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
