List files and directories in DBFS (Databricks File System).
AI agents call list_dbfs_files to retrieve information from Databricks MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates file system contents without creating, modifying, or deleting any data. It is a straightforward information retrieval operation with minimal blast radius if misused—worst case would be unauthorized enumeration of file paths. No code execution, data modification, or destructive actions are possible.
