Search non-trashed notes by title/body, optionally filtered to a tag (matches the tag and its nested subtags). Empty query = most recent. Returns id, title, tags, pinned, modified.

Return a note's {id, title, text, tags, pinned, todo_open, todo_done}.

List every tag with the number of non-trashed notes it holds.

Bear's [[wiki-link]] graph for a note: backlinks (notes linking TO it) and links_to (notes it links to). Trashed notes excluded.

Create a new note (its title becomes the H1 line). No token required.

Append text to the end of an existing note.

Prepend text to a note (Bear inserts it just after the title line).

Overwrite a note's ENTIRE text, including its title line — pass the full text as returned by read_note (not body-only), or the title changes.

Backs up the current text first to ~/.bear-mcp-backups/. Note the backup is a read-only DB snapshot and may lag edits still open unsaved in Bear's UI.

Check/uncheck one checkbox line in a note, found by substring match. done=None flips it, True checks, False unchecks. Errors if match is ambiguous (rather than guessing). Backs the note up first.

Open and focus a note in the Bear app window.
