WHAT IT DOES

What unity_animation_add_parameter does on Unity MCP Server

AI agents use unity_animation_add_parameter 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.

RISK

Why unity_animation_add_parameter is rated Medium

This tool modifies Unity project data by adding new animator parameters. While the changes are reversible and don't execute arbitrary code or delete data, they do alter the state of a game asset (the Animator Controller). The severity is medium because misuse could corrupt animation logic or create invalid states, but damage is scoped to animation configuration and can be undone.

From the tool's definition Tool description states it 'Add[s] a parameter to an Animator Controller', which creates or modifies animation state machine configuration. The action is reversible (parameters can be removed), making it Write rather than Destructive.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs unity_animation_add_parameter safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Unity MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unity_animation_add_parameter, this is the rule to start with:

unity_animation_add_parameter Rate-limited

unity_animation_add_parameter 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 Unity MCP Server, apply this rule, and every unity_animation_add_parameter call is checked against it from then on.

FAQ

Questions about unity_animation_add_parameter

What does the unity_animation_add_parameter tool do? +

Add a parameter to an Animator Controller (Float, Int, Bool, or Trigger). 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.

How do I enforce a policy on unity_animation_add_parameter? +

Register the Unity MCP Server MCP server in PolicyLayer and add a rule for unity_animation_add_parameter: 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.

What risk level is unity_animation_add_parameter? +

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

Can I rate-limit unity_animation_add_parameter? +

Yes. Add a rate_limit block to the unity_animation_add_parameter 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 unity_animation_add_parameter completely? +

Set action: deny in the PolicyLayer policy for unity_animation_add_parameter. 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 unity_animation_add_parameter? +

unity_animation_add_parameter 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.
