Why anim_player_create is rated Medium
This tool creates a new AnimationPlayer node in what appears to be a game engine or animation framework (likely Godot based on the node-based architecture and naming conventions). Creation of scene nodes is a Write operation—it modifies the scene structure reversibly. The explicit '(undoable)' annotation confirms this is not destructive.
From the tool's definition Tool description states 'Add an AnimationPlayer node under a parent (undoable)' and 'Seeds an empty default animation library'. The term 'Add' indicates creation of a new node; '(undoable)' confirms the action is reversible via undo mechanism.
Attacks that exploit this kind of access
The rule that runs anim_player_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 anim_player_create, this is the rule to start with:
anim_player_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.
The button opens the PolicyLayer dashboard: create your workspace, connect Breakpoint, apply this rule, and every anim_player_create call is checked against it from then on.

Register the Breakpoint MCP server in PolicyLayer and add a rule for anim_player_create: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Breakpoint. Nothing to install.
anim_player_create is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the anim_player_create rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
