WHAT IT DOES

What set_ownership does on Sbox

AI agents use set_ownership 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 set_ownership is rated Medium

This tool modifies the ownership state of a networked GameObject, which is a reversible write operation (ownership can be transferred again). It does not delete data or execute arbitrary code, but misuse could disrupt multiplayer game state by reassigning control of objects to unintended connections.

From the tool's definition Transfer network ownership of a GameObject to a different connection, or take/drop ownership

RECOMMENDED RULE

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

set_ownership Rate-limited

set_ownership 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_ownership call is checked against it from then on.

FAQ

Questions about set_ownership

What does the set_ownership tool do? +

Transfer network ownership of a GameObject to a different connection, or take/drop ownership. 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 set_ownership? +

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

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

Can I rate-limit set_ownership? +

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

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

set_ownership 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.
