Remove and return the last element from a Redis list.
AI agents call rpop to permanently remove resources in Redis MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
RPOP irreversibly removes an element from a Redis list. Once popped, the element is gone from the list and cannot be recovered (Redis has no built-in undo). This constitutes an irreversible deletion of data, placing it in the Destructive category. The blast radius is high because a misuse could systematically drain list contents.

Attacks that exploit this kind of access
Remove and return the last element from a Redis list. It is categorised as a Destructive tool in the Redis MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Redis MCP Server MCP server in PolicyLayer and add a rule for rpop: 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 Redis MCP Server. Nothing to install.
rpop 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 rpop 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 rpop. 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.
rpop is provided by the Redis MCP Server MCP server (yuchenhui/mcp-redis). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
