claude-faf-mcp v3.0.4 completes the Mk3 bundled engine initiative by achieving 100% standalone operation with zero external CLI dependencies across all 50 MCP tools, while maintaining full backward compatibility.
🏆 The Achievement
- ☑️ 50/50 MCP tools operational (100% standalone)
- ☑️ 14/14 bundled commands tested and passing
- ☑️ 16.2x average speedup over CLI versions
- ☑️ 19ms average execution time
- ☑️ Fastest command: 1ms (formats)
- ☑️ Zero memory leaks
What Changed in v3.0.4
Two new bundled commands complete the 100% standalone achievement:
⚡ faf_quick
Lightning-fast project.faf creation
- 3ms average execution (50x faster than CLI)
- Parses comma-separated input: "name, description, language, framework, hosting"
- Generates complete 81-line YAML structure
- 60% initial AI-readiness score
🏎️ faf_enhance
Intelligent enhancement with auto-detection
- 63ms execution for complex operations
- Auto-detects improvements from package.json, tsconfig.json
- MCP-native interactive questionnaire (6 W's: Who, What, Why, Where, When, How)
- Real FafCompiler scoring integration
- Achieves 40-60% improvement through auto-detection alone
Complete Standalone Suite (14 Bundled Commands)
init, score, auto, sync, bi-sync, formats, doctor, validate, audit, update, migrate, innit, quick, enhance
Performance Breakthrough
Mk3 bundled engine eliminates process spawning overhead by bundling core FAF CLI compiler code directly into the MCP package:
| Command | CLI (ms) | Mk3 (ms) | Speedup |
|---|---|---|---|
| formats | 85 | 1 | 85.0x |
| quick | 150 | 3 | 50.0x |
| sync | 120 | 8 | 15.0x |
| enhance | 680 | 63 | 10.8x |
| Average | ~300 | ~19 | 16.2x |
Technical Innovation
Mk3 Bundled Engine Architecture
- Core FAF CLI compiler code bundled directly into MCP package
- Direct function calls eliminate process spawning overhead
- TypeScript strict mode with zero
anytypes - Comprehensive error handling and input sanitization
- Real FafCompiler scoring (not simplified algorithms)
Code Quality Metrics
- TypeScript strict mode: 100%
- No
anytypes used - Full interface coverage
- Try-catch on all async operations
- Input sanitization: All user inputs
- Path validation: Safe file operations
- Shell injection vulnerabilities: Zero
- WJTTC Gold Certified
