AI agents call perform_fuzzy_search to retrieve information from Claude MCP Server Integration without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Fuzzy search is a read-only query operation that locates and returns data matching fuzzy criteria. It has no side effects on the system or data. The tool retrieves information but does not create, modify, delete, or execute external operations. This is consistent with the Read category definition of search and retrieval operations.
From the tool's definition Tool name 'perform_fuzzy_search' and description 'ファジー検索を実行します' (Execute fuzzy search) indicates a search operation that retrieves matching data without modifying, deleting, or executing code.

perform_fuzzy_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 perform_fuzzy_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 perform_fuzzy_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.
