🔒 Privacy & Data Protection

For Educators: FERPA Compliance

Complete FERPA compliance through systematic data anonymization when working with student data:

• Source-level data anonymization 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
• De-anonymization mapping tool for faculty to correlate anonymous IDs with real students locally

All student data is anonymized before it reaches AI systems. See Educator Guide for configuration details.

For Students: Your Data Stays Private

• Your data only: Student tools access only your own Canvas data via Canvas API's "self" endpoints
• Local processing: Everything runs on your machine - no data sent to external servers
• No tracking: Your Canvas usage and AI interactions remain private
• No anonymization needed: Since you're only accessing your own data, there are no privacy concerns

Prerequisites

• Python 3.10+ - Required for modern features and type hints
• Canvas API Access - API token and institution URL
• MCP Client - Claude Desktop (recommended) or other MCP-compatible client

🚀 Code Execution API (New!)

The Canvas MCP now supports code execution patterns for maximum token efficiency when performing bulk operations.

When to Use Each Approach

Traditional Tool Calling (for simple queries):

Ask Claude: "Show me my courses"
Ask Claude: "Get assignment details for assignment 123"

✅ Best for: Single queries, small datasets, quick lookups

Bulk Grade Submissions Tool (for batch grading with predefined grades):

Ask Claude: "Grade these 10 students with their specific rubric scores"

✅ Best for: Batch grading when you already have the grades/scores, concurrent processing

Code Execution (for bulk operations with custom logic):

Ask Claude: "Grade all 90 Jupyter notebook submissions by analyzing each notebook"
Ask Claude: "Send reminders to all students who haven't submitted"

✅ Best for: Bulk processing with custom analysis logic, large datasets, complex conditions

Token Savings Example

Scenario: Grading 90 Jupyter notebook submissions

Example: Bulk Grading

import { bulkGrade } from './canvas/grading/bulkGrade';

await bulkGrade({
  courseIdentifier: "60366",
  assignmentId: "123",
  gradingFunction: (submission) => {
    // Analysis happens locally, not in Claude's context!
    const notebook = submission.attachments?.find(f =>
      f.filename.endsWith('.ipynb')
    );

    if (!notebook) return null; // Skip

    const hasErrors = analyzeNotebook(notebook.url);

    return hasErrors ? null : {
      points: 100,
      rubricAssessment: { "_8027": { points: 100 } },
      comment: "Great work! No errors."
    };
  }
});

Example: Bulk Discussion Grading

Grade discussion posts with initial post + peer review requirements:

import { bulkGradeDiscussion } from './canvas/discussions/bulkGradeDiscussion';

// Preview grades first (dry run)
await bulkGradeDiscussion({
  courseIdentifier: "60365",
  topicId: "990001",
  criteria: {
    initialPostPoints: 10,      // Points for initial post
    peerReviewPointsEach: 5,    // Points per peer review
    requiredPeerReviews: 2,     // Must review 2 peers
    maxPeerReviewPoints: 10     // Cap at 10 pts for reviews
  },
  dryRun: true  // Preview first!
});

// Then apply grades
await bulkGradeDiscussion({
  courseIdentifier: "60365",
  topicId: "990001",
  assignmentId: "1234567",  // Required to write grades
  criteria: {
    initialPostPoints: 10,
    peerReviewPointsEach: 5,
    requiredPeerReviews: 2,
    maxPeerReviewPoints: 10
  },
  dryRun: false
});

Features:

• Automatically analyzes initial posts vs peer reviews
• Configurable grading criteria with point allocation
• Optional late penalties with customizable deadline
• Dry run mode to preview grades before applying
• Concurrent processing with rate limiting
• Returns comprehensive participation analytics

Discovering Available Tools

The Canvas MCP Server includes a search_canvas_tools MCP tool that helps you discover and explore available code execution API operations. This tool searches through the TypeScript code API files and returns information about available Canvas operations.

Tool Parameters:

• query (string, optional): Search term to filter tools by keyword (e.g., "grading", "assignment", "discussion"). Empty string returns all available tools.
• detail_level (string, optional): Controls how much information to return. Options:
  • "names": Just file paths (most efficient for quick lookups)
  • "signatures": File paths + function signatures + descriptions (recommended, default)
  • "full": Complete file contents (use sparingly for detailed inspection)

Example Usage:

Ask Claude in natural language:

• "Search for grading tools in the code API"
• "What bulk operations are available?"
• "Show me all code API tools"

Or use directly via MCP:

// Search for grading-related tools with signatures
search_canvas_tools("grading", "signatures")

// List all available tools (names only)
search_canvas_tools("", "names")

// Get full implementation details for bulk operations
search_canvas_tools("bulk", "full")

// Find discussion-related operations
search_canvas_tools("discussion", "signatures")

Returns: JSON response with:

• query: The search term used
• detail_level: The detail level requested
• count: Number of matching tools found
• tools: Array of matching tools with requested detail level

Usage with MCP Clients

This MCP server works seamlessly with any MCP-compatible client:

1. Automatic Startup: MCP clients start the server when needed
2. Tool Integration: Canvas tools appear in your AI assistant's interface
3. Natural Language: Interact naturally with prompts like:

Students:

• "What assignments do I have due this week?"
• "Show me my current grades"
• "What peer reviews do I need to complete?"
• "Have I submitted everything for BADM 350?"

Educators:

• "Which students haven't submitted the latest assignment?"
• "Create an announcement about tomorrow's exam"
• "Show me peer review completion analytics"

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

API Security

• Your Canvas API token grants access to your Canvas account
• Never commit your .env file to version control
• The server runs locally on your machine - no external data transmission
• Consider using a token with limited permissions if possible

Privacy Controls (Educators Only)

Educators working with student data can enable FERPA-compliant anonymization:

# In your .env file
ENABLE_DATA_ANONYMIZATION=true  # Anonymizes student names/emails before AI processing
ANONYMIZATION_DEBUG=true        # Debug anonymization (optional)

Students don't need anonymization since they only access their own data.

For detailed privacy configuration, see:

• Educator Guide - FERPA compliance and anonymization
• Student Guide - Privacy information for students

Publishing to MCP Registry

This server is published to the Model Context Protocol Registry for easy installation.

Automated Publishing (Recommended)

Publishing is automated via GitHub Actions:

1. Prepare a release:

   # Update version in pyproject.toml
   # Update CHANGELOG if applicable
   git commit -am "chore: bump version to X.Y.Z"
   git push
   

2. Create and push a version tag:

   git tag vX.Y.Z
   git push origin vX.Y.Z
   

3. Automated workflow:

   • Runs tests
   • Builds Python package
   • Publishes to PyPI
   • Publishes to MCP Registry using GitHub OIDC

Prerequisites for Publishing

• PyPI Account: Create account at pypi.org
• Trusted Publisher Setup (recommended, no tokens needed):
  1. Visit PyPI Trusted Publishers
  2. Add a "pending publisher" for your repository:
     • Owner: vishalsachdev
     • Repository: canvas-mcp
     • Workflow: publish-mcp.yml
     • Environment: (leave blank)
  3. This reserves the package name and enables tokenless publishing

Alternative: Use API token (legacy method - not recommended):

• Generate token at PyPI → Account Settings → API tokens
• Add as PYPI_API_TOKEN secret in repository settings
• Update workflow to use password: ${{ secrets.PYPI_API_TOKEN }}

Manual Publishing (Alternative)

For manual publishing:

# Install MCP Publisher
curl -fsSL https://modelcontextprotocol.io/install.sh | sh

# Login using GitHub
mcp-publisher login github

# Publish server
mcp-publisher publish

Registry Validation

The server.json configuration is automatically validated against the MCP schema during CI/CD. To validate locally:

# Download schema
curl -s https://registry.modelcontextprotocol.io/v0/server.schema.json -o /tmp/mcp-schema.json

# Validate (requires jsonschema CLI)
pip install jsonschema
jsonschema -i server.json /tmp/mcp-schema.json
