ListAHORunCaches
AI agents call ListAHORunCaches to retrieve information from Awslabs Valkey without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
List operations typically retrieve or query data without modification. The tool name prefix 'List' conforms to AWS API naming conventions for read-only operations that enumerate resources. Even without description details, the semantic meaning of 'List' in cloud API contexts strongly indicates a Read category tool. Low severity assigned because listing caches is informational with minimal blast radius if misused.
From the tool's definition Tool name 'ListAHORunCaches' indicates a listing/enumeration operation. The 'List' prefix is a strong signal of a retrieval operation with no side effects. Description is empty, reducing confidence slightly.

Register the Awslabs Valkey 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 Awslabs Valkey. 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 Awslabs Valkey MCP server (awslabs.valkey-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
