WHAT IT DOES

What memory_search does on Claude Flow

AI agents call memory_search to retrieve information from Claude Flow 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

Query operation retrieving stored data with no side effects or state modification.

From the tool's definition Searches tenant-local team memory using RuVector index with lexical fallback.

RECOMMENDED RULE

The rule that runs memory_search safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Claude Flow, 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.

View as policy code

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 Claude Flow, apply this rule, and every memory_search call is checked against it from then on.

FAQ

Questions about memory_search

What does the memory_search tool do? +

Searches tenant-local team memory using a tenant-separated RuVector index when available, with an explicitly labelled lexical fallback. Requires team:read. Results are fenced as untrusted stored data. It is categorised as a Read tool in the Claude Flow MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on memory_search? +

Register the Claude Flow MCP server in PolicyLayer and add a rule for memory_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 Claude Flow. Nothing to install.

What risk level is memory_search? +

memory_search is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit memory_search? +

Yes. Add a rate_limit block to the memory_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.

How do I block memory_search completely? +

Set action: deny in the PolicyLayer policy for memory_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.

What MCP server provides memory_search? +

memory_search is provided by the Claude Flow MCP server (claude-flow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
