Roll a full DnD character stat block using 4d6 drop lowest for all 6 stats.
AI agents call roll_stats to permanently remove resources in Dice Roller MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
An AI agent that decides to call roll_stats doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Dice Roller MCP Server is gone — there is no undo for destructive operations.
Attacks that exploit this kind of access
Roll a full DnD character stat block using 4d6 drop lowest for all 6 stats. It is categorised as a Destructive tool in the Dice Roller MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Dice Roller MCP Server MCP server in PolicyLayer and add a rule for roll_stats: 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 Dice Roller MCP Server. Nothing to install.
roll_stats 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 roll_stats 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 roll_stats. 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.
roll_stats is provided by the Dice Roller MCP Server MCP server (swayam-mishra/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
