WHAT IT DOES

What memory_search does on Agent-Memory-OS

AI agents call memory_search to retrieve information from Agent-Memory-OS without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why memory_search is rated Low

The tool name 'memory_search' strongly implies data retrieval or querying without modification. While the description is uninformative, the context of a memory system and the pattern of sibling tool names support classification as Read.

From the tool's definition Tool name is 'memory_search' with an empty description. Based on the naming convention and the sibling tools on this server (memory_add, memory_consolidate, memory_recall_feedback, etc.), 'search' indicates a query/retrieval operation with no side effects.

RECOMMENDED RULE

The rule that runs memory_search safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Agent-Memory-OS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For memory_search, this is the rule to start with:

memory_search Allowed

memory_search is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "memory_search": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Agent-Memory-OS, apply this rule, and every memory_search call is checked against it from then on.
