Full-text search over persistent observations. Returns 300-char previews
AI agents call mem_search to retrieve information from Qontinui MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
mem_search is a read-only query tool that searches and retrieves data from persistent observations without creating, modifying, deleting, or executing any operations. The 300-character preview return indicates it surfaces existing information only. While the server enables visual automation (which could include Execute/Destructive tools like awas_execute), this specific tool is purely informational retrieval.
From the tool's definition Tool performs 'full-text search over persistent observations' with 'returns 300-char previews' — a retrieval operation with no mutation or side effects.
Attacks that exploit this kind of access
Full-text search over persistent observations. Returns 300-char previews. It is categorised as a Read tool in the Qontinui MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Qontinui MCP Server MCP server in PolicyLayer and add a rule for mem_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 Qontinui MCP Server. Nothing to install.
mem_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 mem_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 mem_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.
mem_search is provided by the Qontinui MCP Server MCP server (qontinui/qontinui-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
