Pop value(s) from right of list.
AI agents call list_pop_right to permanently remove resources in Amazon MQ MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Popping values from a list is a destructive read: it both retrieves and removes data. The removal is typically irreversible (the data is gone from the list), making this Destructive rather than Read or Write. Severity is medium as it affects stored list data.
From the tool's definition 'Pop value(s) from right of list' — popping removes elements from the list irreversibly
Attacks that exploit this kind of access
Pop value(s) from right of list. It is categorised as a Destructive tool in the Amazon MQ MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Amazon MQ MCP Server MCP server in PolicyLayer and add a rule for list_pop_right: 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 Amazon MQ MCP Server. Nothing to install.
list_pop_right 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 list_pop_right 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 list_pop_right. 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.
list_pop_right is provided by the Amazon MQ MCP Server MCP server (awslabs.amazon-mq-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
