WHAT IT DOES

What dbg_variables does on Godot Breakpoint

AI agents call dbg_variables 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.

RISK

Why dbg_variables is rated Low

This tool retrieves and displays variable information from a debugger scope without modifying any state, executing code, or affecting the Godot project. It is purely informational and non-destructive, consistent with Read category tools like 'list' and 'get'.

From the tool's definition Tool name 'dbg_variables' with description 'List variables under a scope or a complex value'. The verb 'List' and the read-only nature of querying variable information during debugging indicate no data modification or side effects.

RECOMMENDED RULE

The rule that runs dbg_variables safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Godot Breakpoint, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For dbg_variables, this is the rule to start with:

dbg_variables Allowed

dbg_variables is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "dbg_variables": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Godot Breakpoint, apply this rule, and every dbg_variables call is checked against it from then on.
