WHAT IT DOES

What anim_insert_key does on Godot Breakpoint

AI agents use anim_insert_key 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 anim_insert_key is rated Medium

This tool creates or modifies animation keyframe data within a Godot project. While it modifies existing data (by overwriting keys at the same timestamp), the operation is explicitly marked as "undoable", making it reversible. This fits the Write category (create/modify data reversibly) rather than Destructive (irreversible).

From the tool's definition Tool description states it will "Insert a keyframe on a track at a given time (undoable)" and "A key already at that exact time is overwritten." The action modifies animation data by inserting or overwriting keyframes, which is reversible via undo.

RECOMMENDED RULE

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

anim_insert_key Rate-limited

anim_insert_key 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_insert_key call is checked against it from then on.

FAQ

Questions about anim_insert_key

What does the anim_insert_key tool do? +

Insert a keyframe on a track at a given time (undoable). A key already at that exact time is overwritten. It is categorised as a Write tool in the Godot Breakpoint MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on anim_insert_key? +

Register the Godot Breakpoint MCP server in PolicyLayer and add a rule for anim_insert_key: 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 Godot Breakpoint. Nothing to install.

What risk level is anim_insert_key? +

anim_insert_key is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit anim_insert_key? +

Yes. Add a rate_limit block to the anim_insert_key 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.

How do I block anim_insert_key completely? +

Set action: deny in the PolicyLayer policy for anim_insert_key. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides anim_insert_key? +

anim_insert_key is provided by the Godot Breakpoint MCP server (jlivingston-Cipher/godot-breakpoint-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
