search-memories
AI agents call search-memories to retrieve information from mem0 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on the tool name 'search-memories' and the server's stated purpose of 'semantic search of memory streams', this tool retrieves or queries data from memory storage. It has no side effects—it reads existing data rather than creating (Write), modifying irreversibly (Destructive), executing code (Execute), or moving money (Financial).
From the tool's definition Tool named 'search-memories' in a memory management server context. The name and function indicate semantic search/retrieval of stored memory data without modification.
Attacks that exploit this kind of access
search-memories. It is categorised as a Read tool in the mem0 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the mem0 MCP Server MCP server in PolicyLayer and add a rule for search-memories: 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 mem0 MCP Server. Nothing to install.
search-memories 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 search-memories 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 search-memories. 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.
search-memories is provided by the mem0 MCP Server MCP server (sadiuysal/mem0-mcp-server-ts). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
