Development

Running in Development Mode

For development with auto-rebuild on changes:

npm run watch

Error Handling

The server implements robust error handling:

• API-specific error messages for each platform
• Rate limit handling for GitHub API
• Graceful fallbacks for service unavailability
• Cached responses to reduce API load

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. Use the MCP Inspector for detailed request/response monitoring:

npm run inspector

The Inspector provides:

• Real-time request/response monitoring
• Tool execution tracing
• Error stack traces
• Performance metrics

Caching

Results are cached using node-cache:

• Default TTL: 1 hour
• Separate cache keys per query/limit combination
• Platform-specific caching strategies
• Memory-efficient storage
