What raycast does on Sbox
AI agents call raycast to retrieve information from Sbox without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why raycast is rated Low
Raycast only queries scene physics data; no side effects or modifications.
From the tool's definition Perform a physics raycast... line-of-sight checks, object placement, collision detection
Attacks that exploit this kind of access
The rule that runs raycast 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 raycast, this is the rule to start with:
raycast is read-only, so it stays allowed. 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 raycast call is checked against it from then on.
Questions about raycast
Perform a physics raycast (Scene.Trace.Ray) from start to end — pass both; the handler traces the start→end segment. Useful for line-of-sight checks, object placement, and collision detection. Returns { hit, hitPosition, normal, distance, gameObjectId, gameObjectName } — feed gameObjectId into get_all_properties/set_transform, or visualize the result with debug_draw_ray. A. It is categorised as a Read tool in the Sbox MCP Server, which means it retrieves data without modifying state.
Register the Sbox MCP server in PolicyLayer and add a rule for raycast: 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.
raycast is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the raycast 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 raycast. 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.
raycast 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.
