ListAHORuns
AI agents call ListAHORuns to retrieve information from Amazon ElastiCache Memcached 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 strongly indicates a data retrieval operation with no side effects. Although the description is empty, the tool name provides sufficient evidence for a Read classification. Without evidence of data modification, deletion, or financial impact, Read is the appropriate category. Severity is low because listing operations typically have minimal blast radius even if misused by an AI agent.
From the tool's definition Tool name 'ListAHORuns' follows the 'List' prefix pattern, which typically indicates a read operation that enumerates resources.

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 ElastiCache Memcached MCP Server MCP server (awslabs.memcached-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
