WHAT IT DOES

What add_ragdoll does on Sbox

AI agents use add_ragdoll 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.

RISK

Why add_ragdoll is rated Medium

This tool creates or modifies a game object by adding a physics component to enable ragdoll behavior. It is a reversible operation (the component can be removed or modified), fitting the Write category. Severity is medium because misuse could create unintended physics behaviors affecting game playability, but cannot delete data or execute arbitrary code.

From the tool's definition Tool adds ModelPhysics component to a skinned model, converting it to ragdoll; description explicitly states 'Add ModelPhysics' indicating creation/modification of game object properties.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

add_ragdoll Rate-limited

add_ragdoll 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 add_ragdoll call is checked against it from then on.

FAQ

Questions about add_ragdoll

What does the add_ragdoll tool do? +

Add ModelPhysics to a skinned model so it becomes a ragdoll (physics-driven bones). NOTE: the ragdoll only flops in PLAY mode — it won. 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.

How do I enforce a policy on add_ragdoll? +

Register the Sbox MCP server in PolicyLayer and add a rule for add_ragdoll: 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 add_ragdoll? +

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

Can I rate-limit add_ragdoll? +

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

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

add_ragdoll 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.
