Scored across 21 tools
Each tool targets a distinct action on the VNC server, such as connection management, mouse/keyboard input, screen analysis, clipboard, and system commands. The boundaries between tools are clear, with no overlapping purposes that would cause misselection.
All tools follow a consistent 'vnc_' prefix with snake_case verb_noun naming (e.g., vnc_connect, vnc_mouse_move, vnc_get_screen_info). The pattern is uniform and predictable, with getters consistently using 'get_'.
At 21 tools, the count is slightly above the typical well-scoped range (3-15), but each tool serves a distinct and necessary function for remote desktop automation. The slight heaviness is justified by the breadth of VNC operations covered.
The tool set covers the full spectrum of VNC operations: connect/disconnect, screen capture and analysis (screenshot, OCR, image finding), input methods (mouse, keyboard, typing), clipboard access, system commands, and GUI launching. There are no obvious missing operations that would hinder normal workflows.
