What create_animation does on Godot
AI agents use create_animation to create or update resources in Godot, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
name | string | Yes | Animation name |
length | number | — | Animation length in seconds (default: 1.0) |
library | string | — | Animation library name (empty for default) |
loop_mode | string | — | Animation loop mode |
player_path | string | Yes | AnimationPlayer node path |
Parameters from the server's own tool schema.
Why create_animation is rated Medium
This tool creates new animation resources, which modifies the project state reversibly. It is a Write operation because animations can be deleted or replaced if needed. The severity is medium because while it modifies project data, it doesn't execute arbitrary code, delete critical data, or affect financial systems.
From the tool's definition Tool name 'create_animation' and description 'Create a new animation on an AnimationPlayer' indicate creation of new data (animation resource) in a Godot project.
Attacks that exploit this kind of access
The rule that runs create_animation safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Godot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_animation, this is the rule to start with:
create_animation 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, apply this rule, and every create_animation call is checked against it from then on.
Questions about create_animation
Create a new animation on an AnimationPlayer. It is categorised as a Write tool in the Godot MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
create_animation accepts 5 parameters: name, length, library, loop_mode, player_path. Required: name, player_path. The full parameter table on this page comes from the server's own tool schema.
Register the Godot MCP server in PolicyLayer and add a rule for create_animation: 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. Nothing to install.
create_animation 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 create_animation 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.
Set action: deny in the PolicyLayer policy for create_animation. 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.
create_animation is provided by the Godot MCP server (@keeveeg/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
