FULLY IMPLEMENTED ### File System Tools (5) 1. **list_files** - Directory listing with optional recursion - Returns: path, name, type, size, created, modified, permissions - Supports recursive traversal 2. **read_file** - Read file contents - Input validation with Zod - UTF-8 encoding support 3. **write_file** - Write or create files - Auto-creates parent directories - Overwrites existing content 4. **delete_file** - Delete files or directories - Recursive directory deletion option - Safe error handling 5. **move_file** - Move or rename files - Creates destination directories - Atomic rename operation ### Search Tools (2) 6. **search_files** - Find files by name - Recursive with max results limit (100 default) - Case-insensitive matching - Skips hidden files and node_modules 7. **search_content** - Find text in files - Searches file contents - Returns matching files only - Ignores binary and permission-denied files ### Command Tools (2) 8. **run_command** - Execute allowed shell commands - HMAC allow-list validation - 30-second timeout default - Returns stdout, stderr, exit code 9. **list_allowed_commands** - View permitted commands - Default: ls, find, grep, cat, echo, pwd, whoami, date, uname, which, ffmpeg, convert, imagemagick, sips, file, stat ### System Tools (3) 10. **launch_app** - Launch applications - macOS: uses `open` command - Windows: uses `start` command - Linux: uses direct command execution 11. **get_clipboard** - Read clipboard - macOS: pbpaste - Windows: PowerShell Get-Clipboard - Linux: xclip/xsel 12. **set_clipboard** - Write to clipboard - macOS: pbcopy - Windows: PowerShell Set-Clipboard - Linux: xclip/xsel input ### Automation Tools (3) 13. **create_folder_structure** - Create nested directories - Recursive structure creation - Supports file creation with initial content 14. **bulk_rename** - Rename multiple files - Pattern matching - Prefix/suffix addition - Extension preservation 15. **cleanup_desktop** - Auto-organize files - Categorizes: Documents, Images, Videos, Archives, Code - Moves files to appropriate folders ### Key-Value Store Tools (5) 16. **kv_get** - Retrieve value from store - Returns null if key doesn't exist - Supports any JSON-serializable value 17. **kv_set** - Store key-value pair - Persists to ~/.mcp-kv/store.json - Overwrites existing values 18. **kv_delete** - Remove key from store - Removes entry from persistent storage - Safe if key doesn't exist 19. **kv_list** - List all stored keys - Returns array of all keys - Helps with discovery 20. **kv_clear** - Wipe all data - Clears entire store - Use with caution --- ## 🔐 SECURITY IMPLEMENTATION ### License Validation (Day-1 Monetization) - ✅ HMAC-SHA256 token signature verification - ✅ 90-day expiration enforcement - ✅ Server fails to start without valid license - ✅ Licensee tracking - ✅ Development/production mode differentiation - File: `src/config/license.ts` ### Command Execution Security -
