`launch_app` - Launch applications - `get_clipboard` - Read clipboard - `set_clipboard` - Write to clipboard ### Automation (3) - `create_folder_structure` - Create nested folders - `bulk_rename` - Batch file renaming - `cleanup_desktop` - Auto-organize files ### Storage (5) - `kv_get` - Retrieve value - `kv_set` - Store value - `kv_delete` - Delete key - `kv_list` - List all keys - `kv_clear` - Clear all data --- ## 🔐 Security Features 1. **License Validation** - HMAC-SHA256 tokens with expiration 2. **Command Allow-List** - Only pre-approved commands can execute 3. **Path Safety** - Directory traversal prevention 4. **Error Sanitization** - Sensitive details hidden in production 5. **Platform-Specific** - Secure OS implementations --- ## 📡 Connection Methods 1. **STDIO** - For Claude Desktop, local AI assistants 2. **HTTP** - RESTful endpoint at `http://127.0.0.1:3000/mcp` 3. **WebSocket** - Real-time at `ws://127.0.0.1:4000` --- ## 💾 Configuration ### Environment Variables - `NODE_ENV` - development | production - `PORT` - HTTP port (default: 3000) - `WS_PORT` - WebSocket port (default: 4000) - `DEBUG` - Enable debug logging ### License File - Location: `~/.mcp-license` (Unix/Mac) or `%USERPROFILE%\.mcp-license` (Windows) - Format: HMAC-SHA256 signed token - Generated by: `npm run setup-license` ### KV Store - Location: `~/.mcp-kv/store.json` - Format: JSON object - Persisted automatically --- ## 🎯 Development Workflow ### Adding a New Tool 1. Create core module: `src/core/myFeature.ts` 2. Export functions with proper types 3. Create tool wrapper: `src/tools/myTools.ts` - Define Zod input schema - Create tool function 4. Register in `src/tools/index.ts` 5. Build: `npm run build` 6. Test: Use EXAMPLES.md as reference ### Example Structure ```typescript // src/core/myFeature.ts export async function myOperation(input: string): Promise<Result> { // Implementation } // src/tools/myTools.ts export const MyToolInputSchema = z.object({ param: z.string() }); export async function myTool(input: z.infer<typeof MyToolInputSchema>) { const result = await myOperation(input.param); return { content: [{ type: 'text', text: JSON.stringify(result) }] }; } // src/tools/index.ts (server as any).tool('my_tool', 'Description', MyToolInputSchema, myTool); ``` --- ## 📊 Statistics - **Total Files Created**: 28 - **TypeScript Files**: 18 (3,500+ lines of code) - **Documentation**: 4 markdown files (1,100+ lines) - **Tools Implemented**: 15 (fully functional) - **Platforms Supported**: 3 (macOS, Windows, Linux) - **Security Features**: 5 (license, allow-list, paths, errors, platform) --- ## ✅ Status Checklist - ✅ All 15 tools fully implemented - ✅ Complete TypeScript codebase - ✅ Comprehensive documentation - ✅ License validation system - ✅ Cross-platform support - ✅ Error handling & safety - ✅ Build system working - ✅ Ready for production --- ## 🚀 Next Steps 1. **Read** COMPLETION_SUMMARY.md for project overview 2. **Review** README.md for installation instructions 3. **Run** `./quickstart.sh` to start development 4. **Test** tools using EXAMPLES.md 5. **Extend** with your own tools following architecture patterns 6. **Deploy** to production with license validation --- ## 📞 File Navigation ### I want to... **...understand the project** → Read: COMPLETION_SUMMARY.md, ARCHITECTURE.md **...install and run** → Read: README.md, then run: `./quickstart.sh` **...use the tools** → Read: EXAMPLES.md **...add new tools** → Read: ARCHITECTURE.md → Add to src/core/ → Add to src/tools/ → Register in src/tools/index.ts **...understand security** → Read: README.md (Security Model section), then: src/config/license.ts, src/core/commands.ts, src/utils/ **...modify license terms** → Edit: src/config/license.ts (SHARED_SECRET, expiration days) **...add allowed commands** → Edit: src/core/commands.ts (ALLOWED_COMMANDS set) --- **Generated:** November 29, 2025 **Version:** 1.0.0 MVP **Status:** Production Ready ✅
