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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "connect_shader_graph_nodes",
    "arguments": {
      "path": "<path>",
      "to_node": 0,
      "to_port": 0,
      "from_node": 0,
      "from_port": 0
    }
  }
}
```

## Why connect_shader_graph_nodes is rated Medium

This operation creates or modifies shader graph structure reversibly (connections can be disconnected). While it doesn't execute shader code directly, it alters the visual shader composition, which constitutes a Write operation. The severity is medium because misuse could corrupt shader logic or performance, but the effect is contained to shader assets and reversible.

From the tool's own definition: "The tool name 'connect_shader_graph_nodes' and description indicate it connects node ports in a VisualShader graph, which modifies the shader graph structure by creating new connections between nodes."

Risk signals: Accepts file system path (path)

## Use case

AI agents use connect_shader_graph_nodes 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": {
    "connect_shader_graph_nodes": {
      "limits": [
        {

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