- Filter by sensor subtype
- Grouped display by sensor type
##### Device Resolution
- `crestron_resolve_device` - Natural language device resolution
- Fuzzy matching algorithm with confidence scoring
- Multi-language support (Italian, English, etc.)
- Room context awareness
- Word overlap scoring
- High confidence resolution (≥0.8)
- Multiple candidate suggestions (<0.8)
- Clear disambiguation guidance
#### Technical Implementation
##### Pydantic Models (v2)
- Comprehensive input validation for all tools
- ConfigDict for validation configuration
- Field constraints (min/max, regex, ranges)
- Detailed field descriptions with examples
- Type-safe enums for modes and formats
##### Response Formatting
- Dual format support (JSON/Markdown)
- Smart truncation at 25,000 characters
- Helpful pagination guidance
- Character limit enforcement
- Type-specific formatting for devices
- Grouped displays in Markdown
##### Error Handling
- HTTP status code handling
- Authentication state validation
- Session expiration detection
- Clear error messages with solutions
- Actionable guidance for users
- Partial operation failure tracking
##### Helper Functions
- `authenticate()` - Authentication workflow
- `api_request()` - Unified API calling with auth
- `format_markdown_list()` - List formatting
- `truncate_response()` - Smart response truncation
- `format_device_markdown()` - Device-specific formatting
##### Code Quality
- Full type hints throughout
- Async/await for all I/O operations
- Composable, reusable helper functions
- DRY principle adherence
- Comprehensive docstrings
- MCP best practices compliance
#### Tool Annotations
All tools properly annotated with:
- `readOnlyHint` - Correctly identifies read-only operations
- `destructiveHint` - Flags destructive operations (all false in current impl)
- `idempotentHint` - Marks idempotent operations
- `openWorldHint` - Identifies external system interaction
#### Documentation
- Comprehensive README with:
- Installation instructions
- Usage examples
- API reference
- Workflow examples in multiple languages
- Troubleshooting guide
- Architecture overview
- Security considerations
- Example configuration files:
- .env.example for environment variables
- claude_desktop_config.json for Claude Desktop integration
- This CHANGELOG
- requirements.txt with all dependencies
#### Known Limitations
- Light control endpoints not implemented (not documented in Crestron API)
- Door lock control endpoints not implemented (not documented in Crestron API)
- Media room control endpoints not implemented (not documented in Crestron API)
- Camera control not available (not in Crestron Home REST API)
- Stdio transport only (HTTP/SSE not configured)
- No WebSocket/event streaming (API doesn't support)
- No rate limiting implemented
### Testing
- [x] Python syntax validation (py_compile)
- [x] Import validation
- [x] Pydantic model validation
- [x] Tool registration
- [x] FastMCP initialization
### Future Enhancements
Potential additions for future releases:
