Epic 1, Story 2: FastMCP Migration Batch 2 - Health Assessment Tools

[ma3u]

Overview

Migrate the second batch of 5 health assessment tools from FastMCP to Official MCP SDK, ensuring dynamic FAISS vector DB integration.

Tools to Migrate

• create_health_protocol - Personalized health recommendations with optional parameters
• analyze_supplement_stack - Supplement interaction analysis with list parameters
• analyze_health_topic - Comprehensive topic analysis with FAISS search
• analyze_forum_trends - Forum discussion analysis
• trace_topic_evolution - Topic evolution over time

Key Requirements

1. Dynamic FAISS Integration: All tools must fetch results dynamically from FAISS vector DB, not static strings
2. Complex Parameters: Handle optional parameters, enums, and list types
3. Search Integration: Maintain knowledge_searcher functionality
4. Performance: Keep response time under 3 seconds
5. Feature Flag: ENABLE_BATCH2_MIGRATION for progressive rollout

Acceptance Criteria

• All 5 tools migrated to Official MCP SDK
• Dynamic FAISS vector DB queries working
• Complex parameter handling (optional, enum, list)
• No regression in Batch 1 tools
• MCP Inspector validation passing
• Performance benchmarks met (<3s)
• Feature flag working independently

Technical Approach

• Follow patterns from Batch 1 implementation
• Use Official MCP SDK types.Tool for registration
• Implement in handle_call_tool() with dynamic FAISS queries
• Ensure knowledge_searcher is properly initialized

Testing

Tests will be added to validate:

• Dynamic FAISS retrieval
• Parameter handling variations
• Search functionality
• Performance metrics
• Integration with Batch 1

✅ Batch 2 Implementation Complete

Summary

All 5 health assessment tools have been successfully migrated to Official MCP SDK with dynamic FAISS vector database integration.

Key Achievements

• ✅ Dynamic FAISS Integration: All tools now fetch results in real-time from the vector database
• ✅ Complex Parameters: Full support for optional, enum, and list parameters
• ✅ Feature Flag: ENABLE_BATCH2_MIGRATION for safe rollout
• ✅ Backward Compatibility: Fallback to old implementation when flag disabled
• ✅ Test Coverage: Comprehensive test suite created

Files Created/Modified

New Files:

• src/mcp/batch2_health_tools.py - Core health assessment tools with FAISS integration
• src/test/test_batch2_health_tools.py - Comprehensive test suite
• src/test/test_batch2_integration.py - Integration tests
• test_reports/batch2_implementation_summary.md - Detailed implementation report

Modified:

• src/mcp/mcp_server_clean.py - Integrated Batch 2 tools with feature flag support

Dynamic FAISS Verification

Each tool performs real-time searches:

# Example from create_health_protocol
results = self.search_tool.search(query=search_query, k=15)
# Categorizes and processes actual search results

Tool Implementations

1. create_health_protocol - Personalized protocols with age/gender/activity parameters
2. analyze_supplement_stack - Stack analysis with interaction checking
3. analyze_health_topic - Comprehensive analysis with depth levels
4. analyze_forum_trends - Forum discussion analysis
5. trace_topic_evolution - Cross-source topic evolution tracking

Testing

• Parameter variation tests (optional, required, full)
• List parameter handling verified
• Enum constraints validated
• Feature flag switching tested
• Performance design meets <3s requirement

Next Steps

1. Deploy to staging with feature flag enabled
2. Test with MCP Inspector
3. Monitor performance metrics
4. Progressive production rollout
