# Screen MCP — screenshot, keyboard, and mouse for GUI agents.
#
# Auto-activated when `hyperhive.gui.enable = true`. Wires the
# `hive-screen-mcp` stdio bridge as `extraMcpServers.screen` so claude
# gets five tools: `screenshot`, `type_text`, `key_press`,
# `mouse_move`, and `mouse_click`.
#
# All tools operate in userspace without `/dev/uinput`:
# - `grim` takes screenshots via Wayland screencopy
# - `wtype` handles text + key combos via `zwp-virtual-keyboard-unstable-v1`
# - mouse tools speak RFB `PointerEvent` directly to the local neatvnc
#   server (port `HIVE_GUI_VNC_PORT`) — the VNC backend's native input path
