describe_log_groups
AI agents call describe_log_groups 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 'describe_log_groups' operation retrieves metadata and configuration details about CloudWatch Logs groups without modifying or deleting any data. This is a read-only query operation with no side effects. Confidence is moderate (0.75) rather than high because the tool description is empty, which limits full verification of actual behavior, but the naming convention and context strongly indicate a read operation.
From the tool's definition Tool name 'describe_log_groups' indicates a read operation that queries CloudWatch Logs groups. The 'describe_*' prefix is a standard AWS pattern for read-only retrieval operations.
Attacks that exploit this kind of access
describe_log_groups. 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 describe_log_groups: 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.
describe_log_groups 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 describe_log_groups 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 describe_log_groups. 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.
describe_log_groups 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.
