Canvas MCP Server

This repository contains a Message Control Protocol (MCP) server implementation for interacting with the Canvas Learning Management System API. The server is designed to work with Claude Desktop and potentially other MCP clients.

Note: Recently refactored to a modular architecture for better maintainability. The legacy monolithic implementation has been archived.

Overview

The Canvas MCP Server bridges the gap between Claude Desktop and Canvas Learning Management System, providing educators with an intelligent interface to their Canvas environment. Built on the Message Control Protocol (MCP), it enables natural language interactions with Canvas data while maintaining FERPA compliance through advanced privacy protection features.

🔒 Privacy-First Student Data Protection

The Problem: Using AI tools with student data creates FERPA compliance risks and privacy violations.

What We Built:

• Source-level data anonymization that converts real names to consistent anonymous IDs (Student_xxxxxxxx)
• Automatic email masking and PII filtering from discussion posts and submissions
• Local-only processing with configurable privacy controls (ENABLE_DATA_ANONYMIZATION=true)
• FERPA-compliant analytics: Ask "Which students need support?" without exposing real identities

All student data is anonymized before it reaches AI systems, ensuring complete privacy protection while maintaining full educational functionality.

Prerequisites

• Python 3.10+ - Required for modern features and type hints
• Canvas API Access - API token and institution URL
• Claude Desktop - For MCP integration

Quick Start (Automated Installation)

The fastest way to get started is with our automated installer:

# Clone the repository
git clone https://github.com/vishalsachdev/canvas-mcp.git
cd canvas-mcp

# Run the automated installer
python scripts/install.py

The installer will:

• ✅ Set up Python environment with uv package manager
• ✅ Install all dependencies automatically
• ✅ Create environment configuration template
• ✅ Configure Claude Desktop integration
• ✅ Test the installation

Manual Installation

If you prefer manual setup:

1. Install Dependencies

# Install uv package manager (faster than pip)
pip install uv

# Install the package
uv pip install -e .

2. Configure Environment

# Copy environment template
cp env.template .env

# Edit with your Canvas credentials
# Required: CANVAS_API_TOKEN, CANVAS_API_URL

Get your Canvas API token from: Canvas → Account → Settings → New Access Token

3. Claude Desktop Setup

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "canvas-api": {
      "command": "canvas-mcp-server"
    }
  }
}

Verification

Test your setup:

# Test Canvas API connection
canvas-mcp-server --test

# View configuration
canvas-mcp-server --config

# Start server (for manual testing)
canvas-mcp-server

Available Tools

The Canvas MCP Server provides a comprehensive set of tools for interacting with the Canvas LMS API. These tools are organized into logical categories for better discoverability and maintainability.

Tool Categories

1. Course Tools - List and manage courses, get detailed information, generate summaries
2. Assignment Tools - Handle assignments, submissions, and peer reviews with analytics
3. Rubric Tools - Create, manage, and grade with rubrics
4. Discussion & Announcement Tools - Manage discussions, announcements, and replies
5. Page & Content Tools - Access pages, modules, and course content
6. User & Enrollment Tools - Manage enrollments, users, and groups
7. Analytics Tools - View student analytics, assignment statistics, and progress tracking

Usage with Claude Desktop

This MCP server works seamlessly with Claude Desktop:

1. Automatic Startup: Claude Desktop starts the server when needed
2. Tool Integration: Canvas tools appear in Claude's interface (🔨 hammer icon)
3. Natural Language: Ask Claude things like:
   • "Show me my courses"
   • "Which students haven't submitted the latest assignment?"
   • "Create an announcement about tomorrow's exam"

Troubleshooting

If you encounter issues:

1. Server Won't Start - Verify your Configuration setup: .env file, virtual environment path, and dependencies
2. Authentication Errors - Check your Canvas API token validity and permissions
3. Connection Issues - Verify Canvas API URL correctness and network access
4. Debugging - Check Claude Desktop console logs or run server manually for error output

Security & Privacy Features

FERPA-Compliant Data Protection

• Automatic anonymization of all student data (names, emails, IDs) before AI processing
• PII filtering removes phone numbers, emails, and SSNs from discussion content
• Consistent anonymous IDs maintain educational relationships while protecting identity
• Local-only processing - no data leaves your machine except anonymous analytics

API Security

• Your Canvas API token grants access to your Canvas account
• Never commit your .env file to version control
• Consider using a token with limited permissions if possible
• The server runs locally on your machine and doesn't expose your credentials externally

Privacy Controls

Configure privacy settings in your .env file:

# Enable automatic student data anonymization (recommended)
ENABLE_DATA_ANONYMIZATION=true

# Debug anonymization process (for testing)
ANONYMIZATION_DEBUG=true
