AI agents call memory_search to retrieve information from Wasurenagusa without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and searches data from persistent memory storage, returning only metadata (ID, title, tags) to enable efficient context lookup. It explicitly instructs users to call memory_get_detail for full content, confirming this is purely a read operation. No data is modified, deleted, or executed.
From the tool's definition Tool name 'memory_search' and description indicate it 'searches memory' and 'returns only lightweight index (ID, title, tags)' without retrieving full content. This is a query/retrieval operation with no side effects.

Register the Wasurenagusa 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 Wasurenagusa. Nothing to install.
memory_search 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 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.
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.
memory_search is provided by the Wasurenagusa MCP server (tsutushi0628/wasurenagusa-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
