- ✅ Proper rarity classifications
- ✅ Detailed descriptions
- ✅ Attunement requirements clearly marked
- ✅ Source document tracking
### Armor:
- ✅ 12 armor types with complete statistics
- ✅ Accurate AC calculations
- ✅ Proper category classifications
- ✅ Stealth disadvantage flags
- ✅ Strength requirements where applicable
### Feats:
- ✅ 89 feats with full descriptions
- ✅ Prerequisite requirements clearly marked
- ✅ Benefits properly structured
- ✅ Complete feat descriptions
### Conditions:
- ✅ 15 core D&D conditions

- ✅ Proper game mechanics
## Validation and Error Handling
### Successfully Implemented:
- ✅ Input type validation (strings, numbers, booleans)
- ✅ Parameter range validation (limits, numeric ranges)
- ✅ Query sanitization and trimming
- ✅ Network timeout handling (15 seconds)
- ✅ API response structure validation
- ✅ Graceful error messaging
### Areas for Improvement:
- ⚠️ Zero and negative limit handling
- ⚠️ Invalid enum value validation (rarity, category)
- ⚠️ Long string input validation
- ⚠️ Null parameter error messages
## MCP Tool Integration
### All Tools Successfully Implemented:
1. `search_magic_items` - Working with all filtering options
2. `get_magic_item_details` - Working with name lookup
3. `search_armor` - Working with category and AC filtering
4. `get_armor_details` - Working with name lookup
5. `search_feats` - Working with prerequisite filtering
6. `get_feat_details` - Working with name lookup
7. `search_conditions` - Working with query filtering
8. `get_condition_details` - Working with name lookup
9. `get_all_conditions` - Working for quick reference
### MCP Compliance:
- ✅ Proper JSON-RPC 2.0 response format
- ✅ Structured content responses
