WHAT IT DOES

What project_set_main_scene does on Godot Breakpoint

AI agents use project_set_main_scene 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.

RISK

Why project_set_main_scene is rated Medium

This tool modifies project state (the main scene entry point) in a persistent, reversible manner. While not destructive (the change can be undone), it is a Write operation that alters critical project configuration. Severity is high because misconfiguring the main scene could disable or redirect the entire application flow, though the action is technically reversible.

From the tool's definition Tool name 'project_set_main_scene' and description 'Set the project' indicate modification of project configuration. The main scene is a core project setting that affects application startup behavior.

RECOMMENDED RULE

The rule that runs project_set_main_scene 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 project_set_main_scene, this is the rule to start with:

project_set_main_scene Rate-limited

project_set_main_scene stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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