What anim_add_track does on Godot Breakpoint
AI agents use anim_add_track 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.
Why anim_add_track is rated Medium
This tool creates or modifies animation data by adding a new track to an existing Animation resource. While it performs a state-changing operation in the Godot editor, it is reversible (undo-able) and does not execute arbitrary code, delete data, or move money. It fits the Write category: creates or modifies data reversibly.
From the tool's definition Tool description explicitly states 'Add a track to an Animation and set its target path', which creates new data in the animation system. The mention of '(undoable)' confirms this is a reversible modification, not destructive.
Attacks that exploit this kind of access
The rule that runs anim_add_track 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 anim_add_track, this is the rule to start with:
anim_add_track 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 anim_add_track call is checked against it from then on.
