Tools & capabilities

Fs MCP Rs tools 21

  • list_directorylist direct children of a directory.
  • read_fileread a UTF-8 byte range with explicit offset and length.
  • write_fileatomically create or replace a UTF-8 file. Set `createParents: true` for a new nested path; the server safely creates missing parent directories after validating the allowed root. The default is `false`.
  • search_filesfind paths whose file name contains a string.
  • search_contentcase-insensitive literal or regex search in text files.
  • get_capabilitiesreport sanitized effective limits, roots, protocol versions, and advertised tools.
  • list_treereturn a bounded, deterministic, paginated flat directory tree.
  • apply_patchatomically apply a validated single-file unified text diff; `dryRun` never mutates.
  • file_inforeturn rich metadata and an optional bounded-streaming BLAKE3 digest.
  • create_directorycreate one directory; parents must already exist.
  • removeremove one file or an empty directory.
  • hash_filecalculate a BLAKE3 file hash.

  • delete_noteDelete a note from the Obsidian vault (requires confirmation). Supports permanent delete, vault trash, or system trash.
  • search_notesSearch for notes in the vault by content or frontmatter
  • move_noteMove or rename a note in the vault
  • move_fileMove or rename any file in the vault (binary-safe, file-only, requires confirmation)
  • read_multiple_notesRead multiple notes in a batch (max 10 files)
  • update_frontmatterUpdate frontmatter of a note without changing content
  • get_notes_infoGet metadata for notes without reading full content
  • get_frontmatterExtract frontmatter from a note without reading the content
