List contents of a directory. Returns file and folder names with sizes and modification dates.

Get detailed metadata about a file including size, modification date, and MIME type.

Read the text contents of a file. Only works for text files within the size limit. Binary files (images, videos, executables, etc.) will be rejected.

Compute CRC32, MD5, SHA1, SHA256, and SHA512 hashes of a file.

Verify a file's integrity against a sidecar checksum file. Looks for a sidecar file in the same directory as the target file by appending a hash extension (e.g. for 'movie.mkv' it checks 'movie.mkv.sha256', 'movie.mkv.md5', 'movie.mkv.sfv', etc.). Supported sidecar formats: .sha512, .sha256, .sha1, .md5 (and their *sum variants), and .sfv (CRC32). Returns the algorithm used, the expected hash from the sidecar, the freshly computed hash, and whether they match.

Get a visual tree representation of a directory structure, similar to the 'tree' command.

Summarize all files under a directory grouped by file extension, with counts and total sizes.

Summarize all files under a directory grouped by modification date buckets (Today, Yesterday, This week, This month, This year, Older).

Find the largest files under a directory, sorted by size descending.

Find the most recently modified files under a directory, sorted by date descending.

Compare two directories side by side. Shows files only in the first, only in the second, files that differ, and identical files.

Find potential duplicate files by grouping files with identical sizes then hashing candidates. Uses XXH3-128 with 5 × 2 MiB probabilistic chunk sampling (first, last, and 3 pseudo-random interior chunks per file) — results are potential duplicates, not guaranteed exact matches.

Search for files and folders by name pattern.

Search for text inside files (grep-like). Returns matching lines with line numbers. Only searches text files.

Find the largest directories by total recursive size, sorted by size descending.

Find files modified within a date range. Supports before, after, or between. Results sorted by date descending.

Find files within a size range. Supports min, max, or both. At least one of minSize or maxSize is required. Results sorted by size descending.

Summarize total size, file count, and directory count for a path. Shows top subdirectories by size. Optionally filter by glob pattern to summarize only matching files.

Detect filesystem changes in a directory. On first call (without a previousToken), returns a snapshot token. On subsequent calls, pass the previous token to get a structured diff of added, removed, and modified files. The token is self-contained — no server-side state is stored.

Read the text contents of a file entry inside an archive (ZIP, TAR, TAR.GZ).

List files and directories inside an archive (ZIP, TAR, TAR.GZ). Supports browsing into subdirectories within the archive.
