File contents

Canvas LMS — Course & Assignment Access

Read-only access to Canvas LMS for listing courses and assignments.

Scripts

scripts/canvas_api.py — Python CLI for Canvas API calls

Setup

Log in to your Canvas instance in a browser
Go to Account → Settings (click your profile icon, then Settings)
Scroll to Approved Integrations and click + New Access Token
Name the token (e.g., "Loki Agent"), set an optional expiry, and click Generate Token
Copy the token and add to ${LOKI_HOME:-~/.loki}/.env:

CANVAS_API_TOKEN=your_token_here
CANVAS_BASE_URL=https://yourschool.instructure.com

The base URL is whatever appears in your browser when you're logged into Canvas (no trailing slash).

Usage

CANVAS="python $LOKI_HOME/skills/productivity/canvas/scripts/canvas_api.py"

# List all active courses
$CANVAS list_courses --enrollment-state active

# List all courses (any state)
$CANVAS list_courses

# List assignments for a specific course
$CANVAS list_assignments 12345

# List assignments ordered by due date
$CANVAS list_assignments 12345 --order-by due_at

Output Format

list_courses returns:

[{"id": 12345, "name": "Intro to CS", "course_code": "CS101", "workflow_state": "available", "start_at": "...", "end_at": "..."}]

list_assignments returns:

[{"id": 67890, "name": "Homework 1", "due_at": "2025-02-15T23:59:00Z", "points_possible": 100, "submission_types": ["online_upload"], "html_url": "...", "description": "...", "course_id": 12345}]

Note: Assignment descriptions are truncated to 500 characters. The html_url field links to the full assignment page in Canvas.

API Reference (curl)

# List courses
curl -s -H "Authorization: Bearer $CANVAS_API_TOKEN" \
  "$CANVAS_BASE_URL/api/v1/courses?enrollment_state=active&per_page=10"

# List assignments for a course
curl -s -H "Authorization: Bearer $CANVAS_API_TOKEN" \
  "$CANVAS_BASE_URL/api/v1/courses/COURSE_ID/assignments?per_page=10&order_by=due_at"

Canvas uses Link headers for pagination. The Python script handles pagination automatically.

Rules

This skill is read-only — it only fetches data, never modifies courses or assignments
On first use, verify auth by running $CANVAS list_courses — if it fails with 401, guide the user through setup
Canvas rate-limits to ~700 requests per 10 minutes; check X-Rate-Limit-Remaining header if hitting limits

Troubleshooting

Problem	Fix
401 Unauthorized	Token invalid or expired — regenerate in Canvas Settings
403 Forbidden	Token lacks permission for this course
Empty course list	Try `--enrollment-state active` or omit the flag to see all states
Wrong institution	Verify `CANVAS_BASE_URL` matches the URL in your browser
Timeout errors	Check network connectivity to your Canvas instance
