List the account's notes (most-recently-updated first by default) as summaries: id, filename, title, format, timestamps, and a body excerpt. Filter by folder or format. Both plain and rich notes are listed, but only plain notes can be created or edited through this server.

Read a single note in full (including its complete plain_body) by exact filename (e.g. "ai-sessions.txt") or numeric id. Provide exactly one of filename or id.

Create a new plain-text note. The server derives the filename from the title. To create a note you can address later by an exact filename of your choosing, use append_to_note instead (it creates the note on first write). Plain text only.

Append text to the note with the given exact filename, creating the note if it does not exist yet (find-or-create). This is the primitive for logging: call it repeatedly to accumulate entries (AI session logs, cron output, journal lines) in one note addressed by a stable filename like "ai-sessions.txt". Plain text only.

Update a plain-text note's title, body, and/or folder, addressed by exact filename or numeric id. Only the fields you supply change; omitted fields are left untouched. Rich-format and append-only notes reject body/title edits. Provide exactly one of filename or id.

Delete a note by its numeric id. Append-only notes cannot be deleted via the API. This cannot be undone through this server.

Move a note (by numeric id) into a folder, or out of any folder. Pass a folder_id to file it there, or null to un-file it.

List all folders in the account (id, name, timestamps), ordered alphabetically.

Create a new folder. Folder names are unique (case-insensitive) within the account.

Rename an existing folder, addressed by its numeric id.

Delete a folder by its numeric id. Notes inside it are NOT deleted — they are moved out of the folder (un-filed).
