Canvas LMS MCP Server

An MCP (Model Context Protocol) server that connects AI assistants like Claude to your Canvas LMS account. Query grades, assignments, missing work, and more through natural language.

Perfect for: Parents monitoring their child's academic progress, students tracking their own work, or anyone who wants to interact with Canvas data through AI.

What Can It Do?

Ask Claude things like:

• "What assignments are due this week?"
• "Show me missing assignments across all classes"
• "What's my grade in Biology?"
• "Are there any late assignments I should know about?"
• "What's on the to-do list for the next 7 days?"

Installation Options

Choose the method that works best for you:

| Method | Best For | Credential Storage | | ------------------------------------------------------------ | ------------------------------ | ------------------------------- | | Desktop Extension | Easy one-click install | OS Keychain (secure) | | Claude Code (CLI) | Developers using Claude Code | Shell env vars or config file | | npm Package | Claude Desktop + 1Password | Config file or password manager | | Standalone CLI | Direct terminal use without AI | Environment variables |

Prerequisites (All Methods)

1. Get Your Canvas API Token

1. Log into your Canvas LMS instance (e.g., https://yourschool.instructure.com)
2. Go to Account → Settings
3. Scroll to Approved Integrations
4. Click + New Access Token
5. Give it a name (e.g., "Claude MCP") and click Generate Token
6. Copy the token immediately - you won't be able to see it again

2. Find Your Canvas Base URL

Your Canvas base URL is the main URL you use to access Canvas:

• https://yourschool.instructure.com
• https://canvas.yourdistrict.org

Option 1: Desktop Extension (Recommended)

The easiest way to get started. Your API token is stored securely in your operating system's keychain.

Install

1. Download the latest .mcpb file from Releases
2. Double-click to install, or drag into Claude Desktop
3. Claude Desktop will prompt you to enter your Canvas credentials
4. Done! Start chatting about your courses

What Gets Stored

• API Token → macOS Keychain / Windows Credential Manager (encrypted)
• Base URL → Claude Desktop settings
• Student ID → Claude Desktop settings (if using observer account)

Option 2: Claude Code (CLI)

For developers using Claude Code, the AI-powered CLI tool.

Requires: Node.js 18+

Quick Setup

1. Add environment variables to your shell profile (~/.zshrc or ~/.bashrc):

export CANVAS_API_TOKEN="your_token_here"
export CANVAS_BASE_URL="https://yourschool.instructure.com"
# Optional for parent/observer accounts:
# export CANVAS_STUDENT_ID="123456"

2. Reload your shell:

source ~/.zshrc  # or source ~/.bashrc

3. Add the MCP server to your Claude Code settings.

Edit ~/.claude/settings.json (global) or .mcp.json (project-level):

{
  "mcpServers": {
    "canvas": {
      "command": "npx",
      "args": ["-y", "@mtgibbs/canvas-lms-mcp"],
      "env": {
        "CANVAS_API_TOKEN": "${CANVAS_API_TOKEN}",
        "CANVAS_BASE_URL": "${CANVAS_BASE_URL}"
      }
    }
  }
}

4. Restart Claude Code - the Canvas MCP will be available.

How It Works

• npx -y automatically downloads the package from npm on first run (no npm install needed)
• The ${VAR} syntax pulls values from your shell environment
• Claude Code will have access to all Canvas tools when chatting

Pre-install for Faster Startup (Optional)

If you prefer to install globally:

npm install -g @mtgibbs/canvas-lms-mcp

Then update your config:

{
  "mcpServers": {
    "canvas": {
      "command": "canvas-lms-mcp",
      "args": [],
      "env": {
        "CANVAS_API_TOKEN": "${CANVAS_API_TOKEN}",
        "CANVAS_BASE_URL": "${CANVAS_BASE_URL}"
      }
    }
  }
}

Option 3: npm Package

For Claude Desktop users who want more flexibility than the Desktop Extension.

Requires: Node.js 18+

Basic Setup

Edit your Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "canvas": {
      "command": "npx",
      "args": ["-y", "@mtgibbs/canvas-lms-mcp"],
      "env": {
        "CANVAS_API_TOKEN": "your_token_here",
        "CANVAS_BASE_URL": "https://yourschool.instructure.com"
      }
    }
  }
}

Restart Claude Desktop after saving.

Securing Your API Token

The basic setup stores your token in plain text. Here are more secure alternatives:

Option A: 1Password CLI (Recommended for 1Password Users)

If you use 1Password, you can inject secrets at runtime so they never touch your config file.

1. Install the 1Password CLI: Download here

2. Store your Canvas credentials in 1Password (note the vault and item names)

3. Create a wrapper script at ~/.config/canvas-mcp-wrapper.sh:

#!/bin/bash
# Canvas MCP 1Password Wrapper

# Ensure 1Password CLI is authenticated
if ! op account get &>/dev/null 2>&1; then
    eval $(op signin)
fi

# Export credentials from 1Password and run the MCP server
export CANVAS_API_TOKEN=$(op read "op://Private/Canvas LMS/token")
export CANVAS_BASE_URL=$(op read "op://Private/Canvas LMS/url")
# Uncomment for observer accounts:
# export CANVAS_STUDENT_ID=$(op read "op://Private/Canvas LMS/student_id")

exec npx -y @mtgibbs/canvas-lms-mcp

4. Make it executable:

chmod +x ~/.config/canvas-mcp-wrapper.sh

5. Update your Claude Desktop config:

{
  "mcpServers": {
    "canvas": {
      "command": "/Users/YOUR_USERNAME/.config/canvas-mcp-wrapper.sh",
      "args": []
    }
  }
}

Now your token lives in 1Password and is only loaded when the MCP server starts.

Option B: Restrict File Permissions

If you must store the token in the config file, at least restrict access:

# macOS/Linux
chmod 600 ~/Library/Application\ Support/Claude/claude_desktop_config.json

For Parent/Observer Accounts

If you're a parent with an observer account linked to your child's Canvas account, add the student ID:

Desktop Extension

Enter the Student ID when prompted during setup.

npm Package

Add CANVAS_STUDENT_ID to your environment variables:

{
  "env": {
    "CANVAS_API_TOKEN": "...",
    "CANVAS_BASE_URL": "...",
    "CANVAS_STUDENT_ID": "123456"
  }
}

Finding Your Child's Student ID

1. Log into Canvas with your observer account
2. The student ID appears in URLs when viewing their information (e.g., /users/123456)
3. Or ask your school's Canvas administrator

Available Tools

Once connected, Claude has access to these capabilities:

| Tool | Description | | -------------------------- | -------------------------------------------------------------- | | get_courses | List all courses with current grades | | get_comprehensive_status | Full academic overview in one call (grades, missing, upcoming) | | get_missing_assignments | Assignments flagged as missing by Canvas | | get_unsubmitted_past_due | Past-due work not yet submitted | | get_recent_grades | Recently graded assignments with scores | | get_upcoming_assignments | Assignments due soon for a specific course | | get_due_this_week | All assignments due across all courses | | list_assignments | Search/filter assignments by status | | get_stats | Late/missing statistics by course | | get_todo | Planner items and to-do list |

Grading Period Filtering

By default, all tools return data for the current grading period only (e.g., Semester 2). This matches what parents see in the Canvas portal and prevents showing old assignments from previous semesters.

Affected tools:

• get_courses - Grades are for the current grading period
• get_missing_assignments - Only shows missing work from the current period
• get_unsubmitted_past_due - Only shows unsubmitted work from the current period
• get_comprehensive_status - All data filtered to the current period

To include all grading periods (e.g., for a full-year view), use the all_grading_periods parameter:

"Show me all missing assignments including previous semesters"
→ Claude will call get_missing_assignments with all_grading_periods: true

For the CLI, use the --all-grading-periods flag:

canvas missing --all-grading-periods
canvas unsubmitted --all-grading-periods

Standalone CLI

This package also includes a standalone command-line tool for querying Canvas directly from your terminal—no AI required.

Installation

# Option 1: Install globally
npm install -g @mtgibbs/canvas-lms-mcp

# Option 2: Run directly with npx (slower startup)
npx @mtgibbs/canvas-lms-mcp courses

Configuration

Set environment variables in your shell profile (~/.zshrc or ~/.bashrc):

export CANVAS_API_TOKEN="your_token_here"
export CANVAS_BASE_URL="https://yourschool.instructure.com"
export CANVAS_STUDENT_ID="123456"  # Optional: for observer accounts

Output Formats

• JSON (default): Machine-readable, great for scripting or piping to jq
• Table: Human-readable formatted output

# JSON output (default)
canvas courses

# Table output
canvas courses --format table

# Pipe JSON to jq for filtering
canvas missing | jq '.[] | select(.points_possible > 50)'

Available Prompts

Prompts are pre-built conversation starters that guide Claude through common workflows:

| Prompt | Description | | -------------------- | -------------------------------------------------------------------------- | | daily-checkin | Quick daily overview of grades, due items, and concerns | | week-planning | Plan the upcoming week with prioritized assignments | | course-analysis | Deep dive into a specific course's performance | | grade-recovery | Find opportunities to improve grades through extra credit or resubmissions | | missing-work-audit | Comprehensive audit of all missing and late work |

Using Prompts

In Claude Desktop, you can trigger prompts directly:

1. Click the prompt icon (📝) in the chat input
2. Select a prompt from the list
3. Fill in any required parameters (like student ID)
4. Claude will execute the workflow using the appropriate tools

Or just ask naturally - Claude will use the right tools:

"Can you do a daily check-in for my student?"

Example Conversations

These examples show realistic interactions, including which tools Claude calls and what output to expect.

Example 1: Daily Check-in

User prompt:

"Give me a quick update on my kid's school situation"

Tools called:

1. get_courses - retrieves all courses with current grades
2. get_missing_assignments - checks for missing work
3. get_due_this_week - finds upcoming deadlines

Claude's response:

Here's today's overview for your student:

Current Grades:

• AP Biology: 92% (A-)
• English 11: 87% (B+)
• US History: 78% (C+)
• Algebra 2: 91% (A-)

Needs Attention:

• "Chapter 12 Reading Quiz" in US History - due yesterday, not submitted
• "Lab Report: Photosynthesis" in AP Biology - due 2 days ago

Coming Up This Week:

• Essay Draft (English 11) - due Thursday
• Unit Test (Algebra 2) - due Friday

I'd recommend prioritizing those two missing assignments first, especially the History quiz since that class has the lowest grade.

Example 2: Finding Missing Work

User prompt:

"What assignments are missing across all classes?"

Tools called:

1. get_missing_assignments - gets Canvas-flagged missing items
2. get_unsubmitted_past_due - catches items Canvas may have missed

Claude's response:

I found 4 missing assignments:

| Assignment | Course | Due Date | Points | | -------------------------- | ---------- | -------- | ------ | | Chapter 12 Reading Quiz | US History | Jan 18 | 20 | | Lab Report: Photosynthesis | AP Biology | Jan 16 | 50 | | Vocabulary Set 8 | English 11 | Jan 15 | 15 | | Problem Set 7.3 | Algebra 2 | Jan 10 | 25 |

Total points at risk: 110 points

The Biology lab report is worth the most - I'd start there. The Algebra problem set is oldest, so check if late submissions are still accepted.

Example 3: Planning the Week

User prompt:

"What's due in the next 7 days? Help me prioritize."

Tools called:

1. get_due_this_week - retrieves all assignments due in the next 7 days
2. get_stats - gets late/missing statistics for context

Claude's response:

Here's what's coming up in the next 7 days:

High Priority (worth 50+ points):

• Unit 5 Test (Algebra 2) - Friday, Jan 24 - 100 points
• Research Paper Draft (English 11) - Thursday, Jan 23 - 75 points

Medium Priority:

• Lab Questions (AP Biology) - Wednesday, Jan 22 - 30 points
• Map Quiz (US History) - Tuesday, Jan 21 - 25 points

Lower Priority:

• Discussion Post (English 11) - Sunday, Jan 26 - 10 points

Suggested Schedule:

• Monday: Start research paper outline
• Tuesday: Map quiz prep + continue paper
• Wednesday: Bio lab questions
• Thursday: Finish and submit paper
• Friday: Algebra test prep

Note: US History currently has 2 missing assignments, so staying current there is important.

Troubleshooting

"CANVAS_API_TOKEN is required"

Your API token isn't being passed correctly. Double-check:

• The token is in the env section of your config
• There are no extra spaces or quotes around the token
• The config file is valid JSON
• If using 1Password wrapper, run it manually to test: ~/.config/canvas-mcp-wrapper.sh

"CANVAS_BASE_URL is required"

Make sure your Canvas URL is set and includes https://.

Server not appearing in Claude

• Restart Claude Desktop completely
• Check that your config file is valid JSON (use a JSON validator)
• Ensure Node.js 18+ is installed: node --version

"Unauthorized" or 401 errors

• Your API token may have expired - generate a new one
• Make sure the token has the necessary permissions
• Verify the base URL is correct (no trailing slash)

Can't see student data (parent accounts)

• Verify CANVAS_STUDENT_ID is set correctly
• Confirm your observer account is properly linked to the student in Canvas
• Try the student ID without quotes (as a number)

1Password wrapper not working

• Run op signin manually first to authenticate
• Check that the item path matches your vault: op read "op://VaultName/ItemName/field"
• Ensure the wrapper script is executable: chmod +x ~/.config/canvas-mcp-wrapper.sh
