Canvas MCP Server

A Model Context Protocol (MCP) server for interacting with the Canvas API. This server allows you to manage courses, assignments, enrollments, and grades within Canvas.

Prerequisites

• Node.js: Version 18 or higher

• Canvas API Token: Obtain from your Canvas account

• Canvas Domain: Typically canvas.instructure.com

Setup

1. Clone the Repository

   git clone https://github.com/yourusername/canvas-mcp-server.git cd canvas-mcp-server

2. Install Dependencies

   npm install

3. Configure Environment Variables

Copy the example environment file:

Edit .env and replace the placeholder values with your actual Canvas API token and domain.

Build the Project

4. Run the Server

   npm start

   The server will start and listen for MCP requests via stdio.

Connecting to Claude Desktop

1. Update Claude Configuration

   Add the MCP server configuration to your claude_desktop_config.json:

Restart Claude Desktop

Quit Claude Desktop completely. Start Claude Desktop again. Navigate to the 🔌 menu to find and connect your Canvas MCP server.

Available Tools (more student focused stuff coming soon)

• canvas_create_course: Create a new course in Canvas.

• canvas_update_course: Update an existing course in Canvas.

• canvas_create_assignment: Create a new assignment in a Canvas course.

• canvas_update_assignment: Update an existing assignment.

• canvas_submit_grade: Submit a grade for a student's assignment.

• canvas_enroll_user: Enroll a user in a course.

Error Handling

Tools return error messages with isError: true to indicate issues. Ensure all required environment variables are set to avoid runtime errors.

Troubleshooting

• Build Errors:

Check TypeScript version: npx tsc --version Clean and rebuild: rm -rf build/ && npm run build

• Runtime Errors:

  Check logs for detailed error messages. Ensure environment variables are correctly set.

• Type Errors:

  Validate types using TypeScript's type checking: npx tsc --noEmit

Additional Notes

• Type Safety: The types.ts file ensures that all interactions with the Canvas API are type-safe, reducing runtime errors and improving code maintainability.

• Error Handling: The server gracefully handles errors by returning meaningful messages with the isError flag, allowing the client (e.g., Claude Desktop) to understand and react appropriately.

• Environment Variables: Sensitive information like API tokens are managed through environment variables, enhancing security and flexibility across different environments.

• Modularity: Separating concerns into different files (types.ts, client.ts, index.ts) makes the codebase easier to navigate and maintain.
