Authenticate with Apache Zeppelin using username and password. Must be called before any other tools. Stores session cookie for subsequent requests.

List notebooks in Zeppelin. Use the query parameter to filter by path (case-insensitive substring match). Without a query, returns all notebooks (can be very large).

Get a notebook's structure: paragraph IDs, status, and first line of text. Use get_paragraph for full content of a specific paragraph.

Update a paragraph's text. Use this to write or modify code in a paragraph.

Add a new paragraph to a notebook. Optionally specify text and position index.

Cancel a running paragraph.

Execute all paragraphs in a notebook sequentially.

Cancel all running paragraphs in a notebook.

Restart a Zeppelin interpreter by setting name (e.g. 'spark', 'python', 'sh', 'md'). Optionally scope to a specific notebook.
