Code Architecture

The server is built with:

• TypeScript for type safety and modern JavaScript features
• @modelcontextprotocol/sdk for MCP protocol implementation
• Zod for runtime type validation and schema generation
• SchaleDB API as the primary data source

Key Components

• BlueArchiveMCPServer: Main server class handling MCP protocol
• SchaleDBClient: API client for data fetching
• ErrorHandler: Centralized error handling and logging
• ParameterHandler: Input validation and normalization
• Logger: Structured logging system

Troubleshooting

Common Issues

Connection Problems

• Symptom: Server fails to start or connect
• Solution: Check Node.js version (18+ required) and verify configuration paths

Data Loading Failures

• Symptom: API requests return empty results
• Solution: Verify internet connection and SchaleDB API availability

Tools Not Appearing

• Symptom: Tools don't show up in Claude Desktop
• Solution: Restart Claude Desktop after configuration changes

Debug Mode

Enable debug logging by setting the environment variable:

LOG_LEVEL=debug npm start

Performance Optimization

• Data is cached for 5 minutes by default
• Use detailed=false for faster responses when full data isn't needed
• Limit result sets with the limit parameter
