--- document: JWT Corruption Investigation Task version: 1.0.0 status: completed author: Claude Desktop created: 2025-06-29 last_updated: 2025-06-30 completed_by: Claude Code completion_date: 2025-06-30 --- # Task: Execute JWT Corruption Investigation **Priority**: Critical **Created**: 2025-06-29 **Estimated Duration**: 30-45 minutes ## 🎯 Objective Execute the JWT corruption tracer to identify the exact point where token corruption occurs in the EuConquisto Composer MCP automation pipeline. ## 🔍 Background The project has JWT token corruption during automated browser sessions. The correct token (3,276 characters) is stored in `correct-jwt-new.txt`, but gets corrupted somewhere in the MCP tool processing pipeline, blocking composition creation functionality. ## 📋 Requirements ### 1. Execute JWT Corruption Tracer - [ ] Run `jwt-corruption-tracer-v1.0.0.js` - [ ] Capture complete step-by-step token integrity analysis - [ ] Document exact corruption point and character loss pattern - [ ] Generate detailed corruption report with findings ### 2. Test Token Processing Pipeline - [ ] Verify token integrity at each pipeline stage: - File read from `correct-jwt-new.txt` - JavaScript variable assignment - URL construction with base URL - URL parameter extraction - Playwright navigation parameter - Browser execution context - [ ] Document token length at each stage - [ ] Identify first stage where corruption occurs ### 3. MCP Tool Parameter Testing - [ ] Test MCP tool parameter size limitations - [ ] Create test tokens of varying lengths (1000, 2000, 3000, 4000 chars) - [ ] Document maximum parameter size before truncation - [ ] Test with `euconquisto-composer:get-composer-url` tool specifically ### 4. Validation Testing - [ ] Test corruption-proof bypass method using `jwt-solution-v1.0.0.js` - [ ] Verify local redirect server approach works - [ ] Compare results between corrupted and bypass methods - [ ] Document success/failure patterns ## 🛠️ Implementation Notes ### Files to Execute ```bash # Primary investigation node jwt-corruption-tracer-v1.0.0.js # Validation testing node jwt-solution-v1.0.0.js # Corruption-proof automation (if needed) node corruption-proof-automation-v1.0.0.js ``` ### Expected Output - Detailed console logs showing token state at each pipeline stage - Identification of exact corruption point - Character loss pattern documentation - Success/failure validation of bypass methods ### Integration Points - MCP tools: `euconquisto-composer:get-composer-url` - File system: `correct-jwt-new.txt` - Browser automation: Playwright navigation - URL construction: Composer authentication endpoint ## 🔍 Investigation Focus Areas ### High Priority 1. **MCP Tool Parameter Passing**: Most likely corruption point 2. **String Concatenation Logic**: URL construction process 3. **File Reading Process**: Potential encoding issues ### Medium Priority 1. **Playwright URL Handling**: Browser navigation parameters 2. **JSON-RPC Message Limits**: MCP protocol constraints 3. **Browser URL Length Limits**: Client-side constraints ## 📊 Success Criteria ### Investigation Complete When: - ✅ Exact corruption stage identified (which pipeline step fails) - ✅ Character loss pattern documented (how many chars lost) - ✅ Root cause mechanism understood (why corruption happens) - ✅ Validation successful with bypass method ### Report Should Include: - Step-by-step token length progression - Exact corruption point identification - Recommended permanent fix approach - Bypass method validation results ## 🚧 Constraints ### Technical Constraints - JWT token must remain exactly 3,276 characters for authentication - All pipeline stages must preserve token integrity - Browser automation requires complete token for access ### Process Constraints - Execute investigation tools in project root directory - Document all findings for Claude Desktop analysis - Provide specific corruption point details for fix implementation ## 📝 Deliverables ### Required Outputs 1. **Corruption Investigation Report** - Console output from jwt-corruption-tracer execution - Step-by-step token length tracking - Exact corruption point identification 2. **MCP Tool Testing Results** - Parameter size limitation findings - Token truncation threshold documentation - Tool-specific behavior analysis 3. **Bypass Method Validation** - Corruption-proof solution test results - Local redirect server functionality verification - Performance and reliability metrics ### Recommended Next Steps Based on investigation findings, provide recommendations for: - Permanent fix implementation approach - Production deployment strategy - Alternative workaround methods if needed ## 🎯 Timeline **Immediate**: Execute jwt-corruption-tracer-v1.0.0.js (15 min) **Follow-up**: MCP tool parameter testing (15 min) **Validation**: Bypass method verification (15 min) **Total Estimated**: 30-45 minutes --- *This task will provide the definitive analysis needed to resolve the JWT corruption issue and restore full MCP functionality.*
