Implementation Summary: Basecamp MCP Integration

Improvements Made

We've implemented a robust MCP server for Basecamp 3 integration with the following key improvements:

1. Secure Token Storage

• Created a dedicated token_storage.py module for securely storing OAuth tokens
• Implemented thread-safe operations with proper locking mechanisms
• Added token expiration checking and metadata storage
• Stored tokens in a separate JSON file instead of environment variables or session

2. Improved OAuth Application

• Revamped the OAuth app to provide clearer user information
• Added proper token handling and storage
• Implemented secure API endpoints for the MCP server to retrieve tokens
• Added health check and token info endpoints for debugging
• Improved error handling and user feedback

3. Enhanced MCP Server

• Completely restructured the MCP server to align with the MCP protocol
• Implemented connection management with unique connection IDs
• Added proper tool action handling for Basecamp operations
• Improved error handling and logging
• Created endpoints for checking required parameters and connection status

4. Better Authentication Flow

• Separated authentication concerns between the OAuth app and MCP server
• Implemented proper token refresh handling for expired tokens
• Added support for both OAuth and Personal Access Token authentication modes
• Implemented better parameter validation and error messages

5. Testing and Documentation

• Created comprehensive test scripts for verifying the implementation
• Added detailed logging for debugging
• Created a comprehensive README with setup and usage instructions
• Documented the architecture and components for easier maintenance

Architecture

The new architecture follows best practices for OAuth integration:

1. User Authentication: Handled by the OAuth app, completely separate from the MCP server
2. Token Storage: Centralized and secure, with proper expiration handling
3. MCP Server: Focused on the MCP protocol, delegating authentication to the OAuth app
4. Client Library: Clean separation of concerns between authentication, API calls, and search functionality

Next Steps

To further improve this implementation:

1. Production Readiness:

   • Replace file-based token storage with a proper database
   • Add HTTPS support for both the OAuth app and MCP server
   • Implement more robust API authentication between the MCP server and OAuth app

2. Feature Enhancements:

   • Add support for more Basecamp resource types
   • Implement webhook support for real-time updates
   • Add caching for improved performance

3. Security Improvements:

   • Add rate limiting to prevent abuse
   • Implement proper token encryption
   • Add audit logging for security events

This implementation provides a solid foundation for a production-ready Basecamp integration with Cursor through the MCP protocol.
