ListAHORunCaches
AI agents call ListAHORunCaches to retrieve information from Amazon MQ MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'List' prefix universally indicates a read-only operation that queries and returns data without modifying or executing anything. No destructive, financial, or executable actions are implied. The empty description prevents higher confidence, but the name alone is sufficient to classify this as a Read operation with low risk.
From the tool's definition Tool name 'ListAHORunCaches' uses the verb 'List', which indicates a retrieval operation with no side effects. The tool description is empty, limiting direct confirmation, but the naming convention strongly suggests querying or enumerating cached run data.

ListAHORunCaches. It is categorised as a Read tool in the Amazon MQ MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amazon MQ MCP Server MCP server in PolicyLayer and add a rule for ListAHORunCaches: 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.
ListAHORunCaches 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 ListAHORunCaches 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 ListAHORunCaches. 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.
ListAHORunCaches 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.
