AI agents call hybrid_search to retrieve information from Mind Mem without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data from the memory layer without modifying, deleting, or executing external operations. The empty description prevents full certainty, but the name and server context strongly indicate read-only search functionality typical of memory retrieval systems. Classified as Read with high confidence.
From the tool's definition Tool name 'hybrid_search' indicates a search operation; server context describes 'hybrid search' as a memory retrieval capability alongside 'governed Memory OS' with 'contradiction detection'. No write, delete, or execution capability is implied.
Attacks that exploit this kind of access
hybrid_search. It is categorised as a Read tool in the Mind Mem MCP Server, which means it retrieves data without modifying state.
Register the Mind Mem MCP server in PolicyLayer and add a rule for hybrid_search: 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 Mind Mem. Nothing to install.
hybrid_search 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 hybrid_search 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 hybrid_search. 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.
hybrid_search is provided by the Mind Mem MCP server (ovidiu-eremia/mind-mem). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
