AI agents call swarm_search_files to retrieve information from Mcp Swarm without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries file system data based on filename patterns without creating, modifying, deleting, or executing anything. It is a read-only search operation with minimal blast radius—file search results cannot harm systems or data. Classified as Read with low severity.
