--- document: EuConquisto Composer MCP Architecture Analysis version: 1.0.0 status: active author: Claude Desktop created: 2025-06-29 last_updated: 2025-06-29 --- # EuConquisto Composer MCP Architecture Analysis ## 🎯 System Overview The EuConquisto Composer MCP (Model Context Protocol) server provides automated browser-based composition creation and editing capabilities for the EuConquisto educational platform. ## 🏗️ Architecture Components ### 1. MCP Server Foundation ``` Status: ✅ COMPLETE & OPERATIONAL - JSON-RPC 2.0 protocol compliance - Claude Desktop integration - Tool discovery and registration - Sub-100ms response times - Comprehensive error handling ``` ### 2. Authentication System ``` Status: ⚠️ PARTIAL - JWT Corruption Issue - JWT-based authentication for composer.euconquisto.com - Token length: 3,276 characters (when intact) - Authentication endpoint: /embed/auth-with-token/pt_br/home/ - Issue: Token corruption during MCP tool processing ``` ### 3. Browser Automation Layer ``` Status: ❌ BLOCKED - Dependent on Authentication Fix - Playwright-based browser automation - DOM manipulation for composition operations - Element detection and interaction - Screenshot capture for verification - Blocked by JWT corruption preventing authentication ``` ## 🛠️ MCP Tool Inventory ### Working Tools (3/7) 1. **`test-connection`** ✅ - Function: Server connectivity and status validation - Status: Fully operational - Dependencies: None 2. **`get-widget-info`** ✅ - Function: Widget analysis and information retrieval - Status: Fully operational - Dependencies: Widget type database 3. **`get-composer-url`** ✅⚠️ - Function: JWT-authenticated URL generation - Status: URL generation works, JWT may be corrupted - Dependencies: JWT token integrity (ISSUE) ### Blocked Tools (4/7) 4. **`create-new-composition`** ❌ - Function: Create new educational compositions - Blocking Issue: Cannot authenticate due to JWT corruption - Secondary Issue: DOM selector timeouts 5. **`edit-composition-metadata`** ❌ - Function: Edit composition title, description, author, tags - Blocking Issue: Cannot access authenticated interface - Secondary Issue: Hamburger menu element detection 6. **`save-composition`** ❌ - Function: Save composition and return URL with encoded data - Blocking Issue: Cannot reach save interface - Secondary Issue: Save button element detection 7. **`complete-composition-workflow`** ❌ - Function: End-to-end workflow (create → configure → save) - Blocking Issue: Fails at first step (authentication) - Dependencies: All other tools must work ## 🔄 Data Flow Architecture ### Current (Broken) Flow ``` 1. JWT Token (correct-jwt-new.txt) → 3,276 chars ✅ 2. MCP Tool Processing → CORRUPTION POINT ❌ 3. Browser Navigation → Authentication Failure ❌ 4. Composition Operations → Cannot Execute ❌ ``` ### Target (Fixed) Flow ``` 1. JWT Token (correct-jwt-new.txt) → 3,276 chars ✅ 2. Integrity-Preserving Processing → 3,276 chars ✅ 3. Browser Authentication → Success ✅ 4. Composition Operations → Fully Functional ✅ ``` ## 🎯 Core Value Proposition ### Educational Content Creation - **Target Users**: Educators, instructional designers - **Primary Function**: Interactive educational composition creation - **Content Types**: Text, images, lists, galleries, multimedia, quizzes - **Platform Integration**: EuConquisto educational ecosystem ### Automation Benefits - **Efficiency**: Automated composition lifecycle management - **Consistency**: Standardized composition creation workflows - **Integration**: Direct Claude Desktop integration for content creators - **Scalability**: Batch composition operations support ## 🚧 Current System State ### Operational Capacity: 43% (3/7 tools) ``` ✅ Basic Connectivity: Functional ✅ Information Retrieval: Functional ⚠️ URL Generation: Functional but corrupted output ❌ Authentication: Blocked by JWT corruption ❌ Composition Operations: Completely blocked ❌ End-to-End Workflows: Cannot execute ``` ### Production Readiness: ❌ NOT READY - **Primary Blocker**: JWT token corruption in MCP tool chain - **Secondary Issues**: DOM selector optimization needed - **Impact**: Core functionality unavailable - **Risk Level**: Production-blocking ## 🔍 Root Cause Analysis ### Confirmed Working Components - ✅ MCP protocol implementation - ✅ Claude Desktop integration - ✅ Basic tool functionality - ✅ JWT token file integrity - ✅ Error handling framework ### Confirmed Problem Areas - ❌ JWT token processing in MCP tool chain - ❌ Browser authentication workflow - ❌ DOM element detection for composition operations - ❌ End-to-end workflow execution ### Investigation Status ``` Analysis: Complete (architectural understanding) Investigation Tools: Ready (tracer, bypass, solutions) Execution: Pending (Claude Code required) Solution: Designed (corruption-proof alternatives) ``` ## 🛡️ Mitigation Strategies ### Strategy 1: Root Cause Fix (Preferred) - **Approach**: Identify and fix exact corruption point in MCP tool chain - **Benefits**: Permanent solution, maintains architecture - **Timeline**: Dependent on investigation findings - **Risk**: May require MCP protocol changes ### Strategy 2: Corruption-Proof Bypass (Immediate) - **Approach**: Local redirect server bypassing MCP tool processing - **Benefits**: Immediate functionality, proven concept - **Timeline**: Ready for deployment - **Risk**: Architectural complexity increase ### Strategy 3: Hardcoded Token Solution (Testing) - **Approach**: Embed token directly in code bypassing file operations - **Benefits**: Immediate testing capability - **Timeline**: Ready for use - **Risk**: Security and maintenance concerns ## 📊 Success Metrics ### Technical Metrics - **Tool Functionality**: 7/7 tools operational (current: 3/7) - **Response Times**: <100ms for all operations - **Error Rate**: <1% for stable operations - **JWT Integrity**: 100% preservation through pipeline ### Business Metrics - **Workflow Completion**: End-to-end composition creation successful - **User Experience**: No authentication failures or tool timeouts - **Production Readiness**: All blockers resolved - **Demonstration Ready**: Core value proposition functional ## 🎯 Immediate Priorities ### Critical Path (Production Blocking) 1. **Execute JWT Corruption Investigation** (30-45 min) 2. **Implement Permanent Fix or Deploy Bypass** (60-90 min) 3. **Validate Full Tool Functionality** (30 min) 4. **End-to-End Workflow Testing** (45 min) ### Secondary Optimization 1. **DOM Selector Optimization** (after authentication fixed) 2. **Performance Tuning** (after core functionality restored) 3. **Error Handling Enhancement** (after stable operation achieved) --- *This architecture analysis provides the strategic context for JWT corruption resolution and system restoration.*
