WHAT IT DOES

What play_animation does on Sbox

AI agents invoke play_animation to trigger actions in Sbox. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why play_animation is rated High

Playing an animation sequence is an action that triggers an operation in the game engine runtime. It is not merely reading data, nor does it create/modify persistent data structures. It executes a dynamic behavior (animation playback) on a live game object, making Execute the most appropriate category.

From the tool's definition 'Play a named animation sequence on a GameObject' — triggers an external operation (animation playback) on a game object in the s&box engine

RECOMMENDED RULE

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

play_animation Rate-limited

play_animation stays usable, but rate-capped: a runaway agent can't fire it dozens of times 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 play_animation call is checked against it from then on.

FAQ

Questions about play_animation

What does the play_animation tool do? +

Play a named animation sequence on a GameObject. It is categorised as a Execute tool in the Sbox MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on play_animation? +

Register the Sbox MCP server in PolicyLayer and add a rule for play_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 Sbox. Nothing to install.

What risk level is play_animation? +

play_animation is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit play_animation? +

Yes. Add a rate_limit block to the play_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.

How do I block play_animation completely? +

Set action: deny in the PolicyLayer policy for play_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.

What MCP server provides play_animation? +

play_animation 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.
