describe-log-streams
AI agents call describe-log-streams 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.
Despite the empty description lowering confidence slightly, the semantic meaning of 'describe' in AWS APIs consistently refers to retrieving resource metadata and information. This is a read-only operation with no side effects—it queries ElastiCache Memcached log stream information without creating, modifying, or deleting data.
From the tool's definition Tool named 'describe-log-streams' with no description provided. The verb 'describe' indicates a query/retrieval operation typical of AWS API calls that fetch metadata about resources without modifying them. Log stream descriptions are read-only operations.
Attacks that exploit this kind of access
describe-log-streams. It is categorised as a Read tool in the Amazon ElastiCache Memcached MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amazon ElastiCache Memcached MCP Server MCP server in PolicyLayer and add a rule for describe-log-streams: 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 ElastiCache Memcached MCP Server. Nothing to install.
describe-log-streams 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-streams 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-streams. 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-streams 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.
