SDK v0.4.0-preview.3 API cannot be verified due to network access limitations + - Attribute-based API (`[McpServerToolType]`, `[McpServerTool]`) mentioned in research reports does not exist or is incorrectly documented + - No accessible official samples or working code examples + +2. **Existing Implementation Stability** + - ColaFlow's current MCP implementation is **stable, functional, and tested** + - All required features are working: + - ✅ 10 MCP Tools implemented + - ✅ 11 MCP Resources implemented + - ✅ Diff Preview mechanism (unique to ColaFlow) + - ✅ Multi-tenant isolation + - ✅ PendingChange approval workflow + - ✅ API Key authentication + - ✅ Audit logging + +3. **Time vs. Value Trade-off** + - Significant time investment required to decode SDK API + - Uncertain benefits from SDK migration + - **Higher priority**: Focus on product features and user value + +4. **Risk Mitigation** + - SDK is still in preview (v0.4.0-preview.3) + - API may change in future versions + - Better to wait for stable v1.0 release with clear documentation + +#### Actions Taken: + +✅ **Rollback Completed Successfully** + +1. **Removed SDK Code Files** + -
