list_resources
AI agents call list_resources 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.
The tool name 'list_resources' follows standard AWS API patterns for read-only operations that retrieve metadata about existing resources. No side effects, modifications, or destructive actions are implied. The low severity reflects that resource enumeration typically has limited blast radius unless it exposes highly sensitive data, though confidence is slightly reduced due to the missing description.
From the tool's definition Tool name 'list_resources' indicates a retrieval operation that enumerates resources without modification. The empty description limits full certainty, but the naming convention strongly suggests a listing/query operation typical of AWS resource enumeration.
Attacks that exploit this kind of access
list_resources. It is categorised as a Read tool in the Awslabs Valkey MCP Server, which means it retrieves data without modifying state.
Register the Awslabs Valkey MCP server in PolicyLayer and add a rule for list_resources: 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.
list_resources 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 list_resources 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_resources. 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_resources 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.
