List files and directories at a path. Empty path = share root. Denied filenames are omitted from results. Returns JSON.
read_file
Return text contents of a file. Oversized files return a preview (first N lines) or hard-error if READ_PREVIEW_LINES=0. Binary Office/PDF files are parsed into text when supported.
get_file_info
Return metadata (size, type, timestamps) for a file or directory without reading its contents.
search_files
Find files by glob pattern (e.g. *.csv). Recurses to max_depth (default 5, max 10) and returns up to 200 matches.
