WHAT IT DOES

What theme_create does on Breakpoint

AI agents use theme_create to create or update resources in Breakpoint, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Breakpoint environment.

Parameter	Type	Required	Description
`confirm`	boolean	—	Auto-approve this destructive action (skip the confirmation prompt)
`to_path`	string	Yes	Destination res:// path, e.g. res://ui/main.theme or res://ui/main.tres

Parameters from the server's own tool schema.

RISK

Why theme_create is rated Medium

This tool creates and persists a new Theme resource file. While the description claims 'DESTRUCTIVE,' the actual operation is write-based (creating new data), not destructive (deleting/overwriting existing data). The confirmation gate mitigates risk.

From the tool's definition Tool description states 'Create a new empty Theme resource and save it to a res:// path.' The creation of a new file is a write operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs theme_create safely

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

theme_create Rate-limited

theme_create 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.
