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": "get_shader_node_defaults",
    "arguments": {
      "node_type": "<node_type>"
    }
  }
}
```

## Why get_shader_node_defaults is rated Low

This tool queries and returns default configuration metadata for VisualShader nodes. It performs no modifications, deletions, code execution, or financial operations. It simply retrieves and presents existing default parameters, making it a straightforward Read operation with low severity as misuse would only return irrelevant shader data without impacting the system.

From the tool's own definition: "Tool name 'get_shader_node_defaults' and description 'Get default ports and parameters' indicate a retrieval operation with no side effects. The verb 'Get' and the passive nature of retrieving default configuration data confirm this is a read-only query."

## Use case

AI agents call get_shader_node_defaults to retrieve information from Godot without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_shader_node_defaults": {}
  }
}
```
