What delete_script does on Sbox
AI agents call delete_script to permanently remove resources in Sbox, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why delete_script is rated Critical
This tool permanently removes C# script files from a game project without opportunity for recovery through the tool itself. Deletion of source code is a destructive action that cannot be undone via the MCP interface. An AI agent could inadvertently remove critical game logic or scripts, causing significant project damage.
From the tool's definition Tool is named 'delete_script' with description 'Delete a C# script from the project' — the word 'Delete' explicitly indicates irreversible removal of project data.
Attacks that exploit this kind of access
The rule that runs delete_script 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 delete_script, this is the rule to start with:
delete_script is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Sbox, apply this rule, and every delete_script call is checked against it from then on.
Questions about delete_script
Delete a C# script from the project. It is categorised as a Destructive tool in the Sbox MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Sbox MCP server in PolicyLayer and add a rule for delete_script: 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.
delete_script is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_script 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 delete_script. 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.
delete_script 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.
