AI agents call list_secrets to retrieve information from Memex without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves secrets from centralized memory storage—a read operation with no side effects. However, the sensitivity of the data (secrets) and potential exposure risk elevates severity to high. The empty description reduces confidence slightly, but the name clearly indicates a read/query action on sensitive information rather than modification, deletion, or execution.
From the tool's definition Tool name 'list_secrets' indicates retrieval of sensitive secret data. Despite empty description, the name strongly suggests querying stored secrets without modification.
Attacks that exploit this kind of access
list_secrets. It is categorised as a Read tool in the Memex MCP Server, which means it retrieves data without modifying state.
Register the Memex MCP server in PolicyLayer and add a rule for list_secrets: 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 Memex. Nothing to install.
list_secrets 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_secrets 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_secrets. 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_secrets is provided by the Memex MCP server (queflyhq/memex). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
