## Why gd_signature_help is rated Low

This tool retrieves signature information for display purposes only, similar to IDE hover tooltips or parameter hints. It has no side effects, does not modify state, and does not execute code. It is purely informational, matching the Read category definition of retrieving or querying data with no side effects.

From the tool's own definition: "Tool description states it 'Show[s] the call signature(s) and active parameter at a position', which is a read-only operation that retrieves and displays IDE parameter hints without modifying any data or triggering execution."

## Use case

AI agents call gd_signature_help to retrieve information from Godot Breakpoint 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 Breakpoint:

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