# Screen MCP — screenshot + keyboard input for GUI agents.
#
# Auto-activated when `hyperhive.gui.enable = true`. Wires the
# `hive-screen-mcp` stdio bridge as `extraMcpServers.screen` so claude
# gets three tools: `screenshot`, `type_text`, and `key_press`.
#
# All tools use Wayland protocols mediated by the Weston compositor —
# no `/dev/uinput` or kernel-level injection needed. `grim` takes
# screenshots; `wtype` handles both text input and key/modifier combos
# via the `zwp-virtual-keyboard-unstable-v1` protocol.
