Search Zep Cloud memory in a specific session
AI agents call zep_search_memory to retrieve information from Zep MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches persistent memory data stored in Zep Cloud. While it performs data retrieval (a Read operation), the severity is elevated to 'medium' rather than 'low' because: (1) memory systems may contain sensitive conversational context, personal information, or application secrets; (2) unrestricted searches could expose private data across sessions; (3) an AI agent with unfettered search access could extract…
From the tool's definition Tool name 'zep_search_memory' and description 'Search Zep Cloud memory in a specific session' indicate retrieval/query operations. The verb 'search' is characteristic of Read category tools that retrieve data without modification.
Attacks that exploit this kind of access
Search Zep Cloud memory in a specific session. It is categorised as a Read tool in the Zep MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Zep MCP Server MCP server in PolicyLayer and add a rule for zep_search_memory: 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 Zep MCP Server. Nothing to install.
zep_search_memory 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 zep_search_memory 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 zep_search_memory. 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.
zep_search_memory is provided by the Zep MCP Server MCP server (wastrilith2k/zep-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
