memory_get_event
AI agents call memory_get_event 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.
Valkey (Redis fork) GET operations retrieve data without modification or side effects. Even though the description is empty, the tool name strongly suggests a read operation ('get') on cached event data. In a cache context, this poses minimal security risk—it retrieves existing data without persistence changes, user impact, or external effects. Low severity reflects limited blast radius if misused.
From the tool's definition Tool name 'memory_get_event' in a Valkey/Redis cache context indicates retrieval of events from memory storage. No description provided, but the 'get' operation pattern is characteristic of read-only data retrieval.
Attacks that exploit this kind of access
memory_get_event. 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 memory_get_event: 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.
memory_get_event 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 memory_get_event 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 memory_get_event. 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.
memory_get_event 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.
