## 🎯 Success Criteria (End of Week 2)
### Must Have
- ✅ MCP server builds without errors
- ✅ 2 core tools working (get_seo_context, scan_site)
- 🚧 Response time < 2 seconds
- 🚧 Graceful error handling
- 🚧 Documentation complete
- 🚧 3+ beta users testing
### Nice to Have

## 🐛 Known Issues
None yet (awaiting testing)

## 💡 Lessons Learned
1. **MCP SDK is straightforward** - stdio transport works well
2. **Caching is essential** - avoids hammering backend
3. **URL resolution is tricky** - need framework detection
4. **Type safety matters** - Zod validation catches errors early
