Nova
未认领Give an LLM agent control of the macOS desktop — a single self-contained Rust binary (no Python/JS stack) that speaks MCP: screenshots, Set-of-Mark targeting, Apple Vision OCR, mouse & keyboard.

npx -y @bigduu/nova --version工具（9 个）
ax_activate
Activate an exact actionable node from a fresh axread; rejects stale snapshot IDs and reports route=ax\
ax_read
Canonical ax:read: read semantic labels, text, values, roles, actions, state, and optional bounds through macOS Accessibility or Windows UIA, without a screenshot. Returns an ephemeral snapshot/node protocol and explicit coverage/status.
batch_actions
Run a sequence of input actions in one call.
click_mark
Compatibility action for the latest numbered mark; prefer generation-safe axactivate.
ocr
Recognize on-screen text via Apple Vision (on-device, no model files). Returns each text line with a clickable center — read and click text on canvas/Electron/game surfaces where marks are empty. CJK + Latin.
read_ui
Compatibility alias backed by the same axread traversal and cache generation.
screenshot
Capture the whole display or a single window= — use for layout, icons, colors, images, canvas, and visual verification after semantic/OCR paths.
wait
Pause for a specified number of seconds.
zoom_region
Magnify a rectangle of the last screenshot at native resolution — reads small targets on surfaces with no Accessibility tree.
