Motion.dev MCP Server

# Motion.dev MCP Tool Analysis Report ## Executive Summary The Motion.dev MCP tool collection has been comprehensively tested across all 9 available functions. While the tool interfaces are well-designed and responsive, there are significant issues with content availability and functionality that severely limit its practical usefulness. ## Tool Testing Results ### 1. Documentation Tools #### `get_motion_docs` - **Status**: ❌ Non-functional - **Issue**: Returns empty results despite successful API calls - **Test Input**: `https://motion.dev/docs` - **Result**: `{"success": true, "totalFound": 0, "queryTime": 0}` #### `search_motion_docs` - **Status**: ❌ Non-functional - **Issue**: No search results for basic queries - **Test Input**: "framer motion", "animation basics" - **Result**: Empty results array consistently ### 2. Component API Tools #### `get_component_api` - **Status**: ❌ Non-functional - **Issue**: Cannot find documentation for basic components - **Test Input**: "motion.div", "motion" - **Result**: "No API documentation found for component" errors #### `get_examples_by_category` - **Status**: ❌ Non-functional - **Issue**: Returns empty examples for all categories - **Test Input**: category="animation", framework="react" - **Result**: `{"examples": [], "totalFound": 0}` ### 3. Code Generation Tools #### `generate_motion_component` - **Status**: ❌ Partially functional - **Issues**: - Unknown animation patterns ("scale", "rotate") - Generates empty code blocks - **Test Results**: - Basic generation: Returns empty code with metadata - Advanced patterns: "Unknown animation pattern" errors #### `create_animation_sequence` - **Status**: ✅ Functional - **Success**: Only fully working tool - **Output**: Generated valid React component with proper TypeScript - **Code Quality**: Clean, production-ready implementation ### 4. Code Processing Tools #### `optimize_motion_code` - **Status**: ❌ Non-functional - **Issue**: JavaScript parsing errors - **Error**: "Expecting Unicode escape sequence \\uXXXX" - **Test Input**: Basic Framer Motion component #### `convert_between_frameworks` - **Status**: ⚠️ Partially functional - **Issues**: - Returns empty code blocks - Only provides metadata and warnings - **Positive**: Proper warning messages about conversion complexity #### `validate_motion_syntax` - **Status**: ⚠️ Questionable functionality - **Issue**: Returns "valid: true" for clearly invalid code - **Test Input**: `<motion.div animate={{invalid: true}} />` - **Result**: No validation errors detected ## Root Cause Analysis ### Primary Issues 1. **Empty Content Database** - Documentation search returns no results - Component API lookup fails - Example repository appears empty 2. **Missing Animation Pattern Library** - Basic patterns like "scale" and "rotate" are unrecognized - No predefined animation library available 3. **Parser/Syntax Issues** - Code optimization fails due to parsing errors - JavaScript/TypeScript content processing broken 4. **Validation Logic Problems** - Syntax validator accepts invalid code - No proper error detection mechanism ### Secondary Issues 1. **Inconsistent Error Handling** - Some tools return success with empty results - Others return proper error messages 2. **Documentation Mismatch** - Tool descriptions suggest rich functionality - Actual implementation lacks content ## Developer Suggestions ### Critical Fixes (Priority 1) 1. **Content Database Population** ``` - Populate Motion.dev documentation database - Add Framer Motion API references - Include comprehensive example library ``` 2. **Animation Pattern Library** ``` - Add predefined animation patterns (scale, rotate, fade, etc.) - Create pattern validation system - Include customizable animation presets ``` 3. **Code Parser Fix** ``` - Fix JavaScript/TypeScript parsing in optimize_motion_code - Handle JSX syntax properly - Add proper Unicode character support ``` ### Important Improvements (Priority 2) 4. **Validation System Overhaul** ``` - Implement proper Motion/Framer Motion syntax validation - Add property type checking - Include animation property validation ``` 5. **Code Generation Enhancement** ``` - Fix empty code generation in generate_motion_component - Add proper template system - Include working code examples ``` 6. **Framework Conversion** ``` - Complete the framework conversion implementation - Add actual code transformation logic - Improve React to Vue/JS conversion accuracy ``` ### Nice-to-Have Features (Priority 3) 7. **Error Messages** ``` - Standardize error response format - Add helpful error messages with suggestions - Include troubleshooting guidance ``` 8. **Performance Optimization** ``` - Cache frequently accessed documentation - Optimize search algorithms - Add request timeout handling ``` ## Recommendations ### For Developers 1. **Immediate Action Required**: The tool is currently not production-ready 2. **Focus Area**: Content database and animation pattern library 3. **Testing**: Implement comprehensive integration tests 4. **Documentation**: Update tool descriptions to match actual capabilities ### For Users 1. **Current Status**: Tool is not suitable for production use 2. **Alternative**: Use native Framer Motion documentation 3. **Future**: Monitor updates for improved functionality ## Working Example Only `create_animation_sequence` currently produces functional output: ```typescript import React from 'react'; import { motion } from 'framer-motion'; const AnimationSequence: React.FC = () => { const containerVariants = { hidden: { opacity: 0 }, visible: { opacity: 1, transition: {} } }; const itemVariants = { hidden: { opacity: 0, y: 20 }, visible: { opacity: 1, y: 0 } }; return ( <motion.div variants={containerVariants} initial="hidden" animate="visible" > <motion.div variants={itemVariants} transition={{ duration: 0.5, delay: 0 }} > Sequence item 1 </motion.div> </motion.div> ); }; ``` ## Conclusion The Motion.dev MCP tool shows promise in its API design but requires substantial development work to become functional. The primary blockers are content availability and core parsing functionality. With proper implementation, this could become a valuable tool for Motion/Framer Motion development. **Overall Rating**: 1/10 (Not Production Ready) **Recommended Action**: Major refactoring required before public use --- *Report generated on: 2025-08-28* *Testing methodology: Comprehensive tool testing across all available functions*
