感情重み付け検索（Neuro-Logical Search）。キーワードと「その時の気分・空気感」を組み合わせて記憶を検索する。「あの楽しかった話」「あの大変だった時」など感情ベースの検索に最適。
AI agents call recall_memory_neuro to retrieve information from Memory Engine without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read operation that queries stored memory data using emotional and keyword filters. It retrieves information about past sessions and experiences but does not create, modify, delete, or execute external operations. The emotional-weighting aspect is a search refinement parameter, not a capability that changes the read-only nature of the operation.
From the tool's definition Tool performs memory search/retrieval based on keywords and emotional context ("recall_memory_neuro", "感情重み付け検索" = emotional-weighted search). The description indicates it searches and retrieves existing memories without modifying, creating, or deleting data.

Register the Memory Engine MCP server in PolicyLayer and add a rule for recall_memory_neuro: 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 Memory Engine. Nothing to install.
recall_memory_neuro 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 recall_memory_neuro 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 recall_memory_neuro. 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.
recall_memory_neuro is provided by the Memory Engine MCP server (kagioneko/memory-engine-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
