WHAT IT DOES

What project_set_setting does on Godot Breakpoint

AI agents use project_set_setting 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_setting is rated Medium

This tool modifies project settings and can persist changes to disk. Although the description uses 'DESTRUCTIVE' language, the core action is writing/updating configuration data (reversible through re-setting the value), not permanently deleting or purifying data. It belongs in Write category rather than Destructive because the changes can be undone by setting the value back.

From the tool's definition Tool description states 'Write a ProjectSettings value' and explicitly mentions ability to 'persist to project.godot' when save=true. While labeled 'DESTRUCTIVE', the actual mechanism is overwriting configuration settings rather than irreversible deletion.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

project_set_setting Rate-limited

project_set_setting 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_setting call is checked against it from then on.
