macos_file_finder
AI agents call macos_file_finder to retrieve information from Velociraptor MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
File finder tools retrieve and list files without modifying or deleting them—a classic Read operation. However, in an incident response context, file enumeration could help an agent locate sensitive data or malware, creating moderate risk if misused without proper authorization. The empty description reduces confidence slightly, but the name and server context strongly suggest read-only file discovery.
From the tool's definition Tool name 'macos_file_finder' indicates file search/discovery functionality. Server context describes 'file/memory scans' and 'artifact collection' as core forensics operations.

macos_file_finder 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 macos_file_finder 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 macos_file_finder. 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.
