WHAT IT DOES

What mp_set_authority does on Godot Breakpoint

AI agents use mp_set_authority 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 mp_set_authority is rated Medium

The tool modifies existing node configuration/state (authority assignment, presumably for multiplayer synchronization) without deleting data. This is reversible—authority can be reassigned. It's categorized as Write rather than Execute because it sets a property value rather than triggering arbitrary computation.

From the tool's definition Tool name 'mp_set_authority' and description 'Set a node' indicate modification of node properties in the Godot engine. The 'set' verb and action of modifying a node's authority (likely multiplayer-related state) constitutes a write operation.

RECOMMENDED RULE

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

mp_set_authority Rate-limited

mp_set_authority 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.
