Resolves the credential the way real tools do, then makes one authenticated request to canvas. Reports which source supplied the credential, whether canvas accepted it, the round-trip time, and a plain-English hint distinguishing 'no credential' from 'credential rejected' from 'a canvas-side problem'. Read-only; never returns the credential itself. Call this when a real tool fails and you want to know which hop broke.

Get the logged-in user's Canvas profile (id, name, primary_email, login_id, locale, time_zone). Useful first call to confirm credentials.

List students linked to your Canvas observer account. Returns an empty array for plain student tokens.

List active Canvas courses (with course-level grades, total scores, current grading period scores, and term).

Get a single Canvas course with its syllabus, teachers, and term.

List a course's assignments (with the user's submission inline). Supports the standard Canvas bucket filter.

List past-due unsubmitted assignments for the user (or a linked observee). For an observee, courseIds is required.

Get a single submission with rubric assessment and grader comments. userId defaults to 'self'.

List recently graded submissions in a course. Defaults to a 14-day window for the calling user.

List active student enrollments with per-course grades (current_score, final_score, current_grade, final_grade, current grading period info).

List Canvas calendar events or assignments across selected contexts (courses/users).

List the calling user's upcoming events (Canvas's curated next-7-days view).

List planner items (assignments + announcements + planner notes + calendar events) for the user or a linked observee.

List announcements across one or more courses. contextCodes is required (e.g. ["course_123"]). Defaults to active-only.

List Canvas inbox conversations. Optional scope (unread/starred/archived/sent) and filter (array of context codes).

Get a full Canvas conversation thread with all messages. Read-only: does not mark the conversation as read.

List discussion topics for a course (read-only).

List a course's files (metadata only — use canvas_download_file with the url field).

Download a Canvas file to disk. url is the absolute URL from canvas_list_course_files (only file URLs on the configured Canvas host are accepted); destinationPath is required and must be inside the download directory (CANVAS_OUTPUT_DIR, default ~/Downloads).
