Create a new note and return it, including the generated id to use in later calls.

Titles must be unique case-insensitively; creating a note whose title already exists is an error, so if the user wants to change an existing note, use update_note.

Read one note in full by id.

Use this whenever you need a note's complete body — list_notes previews are cut off after 120 characters. Ids come from list_notes or create_note; this tool does not accept titles.

List notes, most-recently-updated first, as previews.

Pass query to filter to notes whose title or body contains that text (case-insensitive substring, not fuzzy or semantic — prefer one distinctive word over a whole phrase, and drop the filter entirely to browse everything).

Each entry carries id, title, preview, content_truncated, content_length, created_at, and updated_at. total_count is the number of matches, which exceeds the returned notes when limit cut the page short.

Overwrite the title and/or content of an existing note and return the updated note.

This REPLACES whatever you pass; it does not merge. Omit a field (or pass null) to leave it alone. To add to a note's body without losing the current text, call get_note first and pass the full combined text as content.

Permanently delete the note with the given id and return what was removed.

This cannot be undone and the note's content is not recoverable, so confirm the id with list_notes or get_note before calling when the user identified the note by description rather than by id.
