So that we understand all technical debt and can plan the migration safely

📄 Documentation

Completed Document: Brownfield Architecture

Work Completed ✅

System Analysis

• ✅ Analyzed multiple MCP server implementations

Key Findings

1. Multiple Server Implementations: 3 different MCP servers causing confusion
2. FastMCP Tool Registration: Complex wrapper extraction in unified_mcp_server.py
3. Deployment Fallbacks: Multiple fallback strategies obscuring issues
4. OAuth Integration: Proprietary Claude.ai endpoints documented
