WHAT IT DOES

What theme_set_color does on Godot Breakpoint

AI agents use theme_set_color 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 theme_set_color is rated Medium

While the tool modifies a file and the description uses the word 'DESTRUCTIVE', the operation itself is a Write action: it creates or modifies a theme color entry reversibly. Changes to color values are not destructive in the sense of irreversible deletion. The 'gated by confirmation' note suggests mitigation exists. Write category applies because the change can be undone by setting a different color value.

From the tool's definition Tool description states: 'Set a color entry on a Theme resource file and save it' — this modifies and persists data to a file.

RECOMMENDED RULE

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

theme_set_color Rate-limited

theme_set_color 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 theme_set_color call is checked against it from then on.
