ListAHORuns
AI agents call ListAHORuns 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.
List operations are retrieval functions that query existing data without modification or side effects. The 'List' prefix in the tool name strongly suggests this is an enumeration/read operation. While the empty description reduces confidence slightly, the naming convention and the context of managing AMQ brokers (where 'List' typically queries run history) supports classification as Read.
From the tool's definition Tool name 'ListAHORuns' indicates a listing operation (List prefix), which is a standard read operation for querying existing entities. No description provided, but the naming pattern is consistent with read-only API calls.
Attacks that exploit this kind of access
ListAHORuns. 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 ListAHORuns: 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.
ListAHORuns 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 ListAHORuns 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 ListAHORuns. 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.
ListAHORuns 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.
