What set_animgraph_param does on Sbox
AI agents use set_animgraph_param to create or update resources in Sbox, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sbox environment.
Why set_animgraph_param is rated Medium
This tool modifies animation parameters on game objects, which is a reversible write operation. It does not execute arbitrary code, delete data, or cause financial impact. The severity is medium because incorrect animation parameters could affect game behavior in unpredictable ways, but the change is reversible and scoped to animation properties on a single game object.
From the tool's definition Tool name 'set_animgraph_param' and description 'Set an AnimationGraph parameter on a GameObject' indicate modification of game object properties. The verb 'Set' is a write operation that changes animation graph state on an existing object.
Attacks that exploit this kind of access
The rule that runs set_animgraph_param safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Sbox, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_animgraph_param, this is the rule to start with:
set_animgraph_param 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 Sbox, apply this rule, and every set_animgraph_param call is checked against it from then on.
Questions about set_animgraph_param
Set an AnimationGraph parameter on a GameObject. It is categorised as a Write tool in the Sbox MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sbox MCP server in PolicyLayer and add a rule for set_animgraph_param: 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 Sbox. Nothing to install.
set_animgraph_param 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 set_animgraph_param 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 set_animgraph_param. 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.
set_animgraph_param is provided by the Sbox MCP server (sbox-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
