Exposes frame/frame_list/frame_doctor/frame_setup as MCP tools so any agent session can SEE a fleet Mac's screen (inline JPEG + OCR/AX/window digest with click coords) without knowing the CLI exists — the discoverability + inline- image win over shelling out to `frame` by hand. Hand-rolled stdio JSON-RPC in the house style (artery/emacs-mcp.mjs, ants/mail-mcp), no SDK, wraps the sibling frame.mjs. Observe-only by design; puppet (act) is a deliberate later add. Registered in .mcp.json alongside emacs + mail. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
