MCP Server Integration

Sequential Thinking MCP

Use for complex frontend reasoning:

Component Architecture:

CopyThink step-by-step about the GameBoard component:
Step 1: What props does it receive? (players, gameType, onBack)
Step 2: What state does it need? (from useGameLogic hook)
Step 3: How should the grid be rendered? (conditional on gameType)
Step 4: How to handle winner overlay? (conditional rendering)
Step 5: How to display real-time logs? (scrollable list with auto-scroll)

State Management Debugging:

CopyAnalyze this state synchronization issue:
Step 1: What is the expected state flow?
Step 2: When does state get out of sync?
Step 3: Are there stale closures in useEffect?
Step 4: Should we use useRef for non-reactive values?
Step 5: How to prevent race conditions?

Performance Optimization:

CopyOptimize rendering performance:
Step 1: What components re-render unnecessarily?
Step 2: Where should useMemo/useCallback be applied?
Step 3: Are there memory leaks in cleanup functions?
Step 4: How can we reduce bundle size?
Step 5: Should we implement code splitting?

Qdrant MCP Server

Store and retrieve backend-specific knowledge:

Storage Keys:

Copyllm-arena:backend:progress:{timestamp}         # Progress snapshots

• After the completion of every task store the progress in Qdrant vector store using qdrant-store
• Save the progress in the format progress.md
• The file needs to include: TODO TASK, IN PROGRESS TASK, COMPLETED TASK

Context7 MCP

Pull live documentation for:

• React: New hooks, server components, use() hook, transitions
• Vite: Configuration, plugins, HMR, build optimization
• Tailwind CSS: New utilities, configuration changes, dark mode
• Framer Motion: Animation patterns, layout animations, gestures
