Summary

• Add authentication support for remote MCP servers (bearer token, API key, basic auth)
• Add environment variable expansion in server configurations
• Enhance error handling and connection resilience

Changes

Authentication Support

• Added auth_type and auth_config fields to MCP server model
• Support for three authentication types:
  • Bearer token authentication
  • API key authentication (with configurable header name)
  • Basic authentication (username/password)
• Authentication headers are automatically added when connecting to remote servers

Environment Variable Support

• Server configurations can now use environment variables with ${VAR} or $VAR syntax
• Variables are expanded in:
  • Command and arguments for stdio transport
  • URL and headers for HTTP+SSE transport
  • Authentication configuration values
• Enables secure configuration without hardcoding sensitive values

Enhanced Error Handling

• Better error messages for connection failures
• Timeout handling for HTTP requests (30 seconds)
• Process startup validation for stdio connections
• Improved error reporting through WebSocket status updates
• Connection status now includes error messages

Database Changes

• Updated MCP server migration to include authentication fields
• No breaking changes to existing data

Testing

• Tested with local stdio MCP servers
• Tested environment variable expansion
• Tested error scenarios (invalid commands, network failures)

Next Steps

• Frontend UI updates to support authentication configuration
• Additional testing with various MCP server implementations
