Set an animation curve on a clip. Define keyframes to animate any property (position, rotation, scale, custom).
AI agents use unity_animation_set_clip_curve to create or update resources in Unity MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Unity MCP Server environment.
This tool modifies animation clip data by creating or updating keyframes. This is a Write operation as it creates/modifies data reversibly—the animation curves can be edited, undone, or overwritten. Severity is high because incorrect animation curves could break game mechanics, affect visual presentation, or corrupt animation state for multiple assets in a project.
From the tool's definition Tool name 'unity_animation_set_clip_curve' and description 'Set an animation curve on a clip. Define keyframes to animate any property' indicate creation and modification of animation data.
Documented attack patterns abuse exactly the kind of access unity_animation_set_clip_curve gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Unity MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for unity_animation_set_clip_curve:
{
"version": "1",
"default": "deny",
"tools": {
"unity_animation_set_clip_curve": {
"limits": [
{
"counter": "unity_animation_set_clip_curve_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}unity_animation_set_clip_curve 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.

Set an animation curve on a clip. Define keyframes to animate any property (position, rotation, scale, custom). It is categorised as a Write tool in the Unity MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Unity MCP Server MCP server in PolicyLayer and add a rule for unity_animation_set_clip_curve: 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 Unity MCP Server. Nothing to install.
unity_animation_set_clip_curve 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 unity_animation_set_clip_curve 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 unity_animation_set_clip_curve. 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.
unity_animation_set_clip_curve is provided by the Unity MCP Server MCP server (anklebreaker-studio/unity-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
