classmarker_list_questionsList the questions of the question bank, 200 per page (page 1, 2, ...): question text, type, category, points, options, correct options, status.

classmarker_create_questionWRITE: add a new question to the question bank. Only multiplechoice, multipleresponse, truefalse and essay can be created. Returns the new question_id.

Use ClassMarker from Claude, Cursor, or any MCP client — groups, links, exams, recent results, categories and the question bank, plus access codes. Hosted, no local install: connect with your own ClassMarker credentials.
