canvas-mcp

Local-first MCP server for Canvas LMS. Stdio transport, no network round-trips beyond the official Canvas API.

Status: alpha. Single-user, no warranty, API surface may still shift. File issues if it breaks.

Why

Canvas is built for instructors. As a student you get a fragmented UI, no cross-course search, and notifications that arrive late or never. This server exposes the Canvas REST API as MCP tools so you can drive the LMS from any MCP-compatible client (Claude Code, Claude Desktop, etc.).

Architecture

[client] ──stdio──> [server.py] ──https──> [Canvas API]

Token lives in ~/.canvas.env (chmod 600)
Server runs locally, no third party in the path
Single file, fully auditable

Tools exposed

list_courses, list_assignments, list_modules, list_announcements, get_page, get_file_info, get_grades, planner_items, upcoming_events, todo.

Setup

1. Mint a Canvas personal access token

In Canvas: Account → Settings → Approved Integrations → + New Access Token. Copy the token shown — it is not retrievable afterwards.

2. Install

python3 -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
cp .canvas.env.example ~/.canvas.env
chmod 600 ~/.canvas.env
# edit ~/.canvas.env: set CANVAS_BASE_URL (institution root, no /api/v1)
# and paste the token into CANVAS_TOKEN

3. Register with your MCP client

Claude Code:

claude mcp add canvas-local -- python3 /path/to/server.py

Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "canvas-local": {
      "command": "python3",
      "args": ["/path/to/server.py"]
    }
  }
}

Bulk dump

dump.py downloads every file the user has access to (course materials, syllabi). Useful for offline indexing.

python3 dump.py              # all active courses
python3 dump.py 12345 67890  # specific course IDs

Output goes to ./canvas-dump/ by default. Override with CANVAS_DUMP_DIR=/path/to/dir.
