EXTRA - Native Computer Use MCP server

Read from the package source without running it. The installed server may list more.

• extra_batch_actionswrite action

  Executes an atomic list of hardware actions sequentially with sub-millisecond dispatch. Eliminates multi-turn network round-trips (reducing seconds to milliseconds) for compound workflows.

• extra_browserwrite action

  Executes web automation via Microsoft Edge / Playwright without vision overhead.

• extra_clickwrite action

  Executes a hardware-level mouse click with PerMonitorV2 DPI compensation and closed-loop stall checking. Supports global fallback visual diffing to eliminate false-stalls when distant viewports change (Fixes #4, credit: @harshbuttru3).

• extra_click_element

  Activates an element previously discovered via extra_inspect_ui or extra_screenshot Set-of-Mark. Tries direct COM InvokePattern in < 1ms first, falling back to physical center hardware click.

• extra_drag

  Performs a smooth click-and-drag from start to end coordinates.

• extra_evolve_skill

  Self-Evolving Learning Loop: crystallizes a discovered zero-stall workflow, resolution, or fast path into a permanent reusable skill playbook (Reflexion style). Patches existing SKILL.md files and persists quirks to KùzuDB memory.

• extra_focus_window

  Forces a target application window to the foreground, bypassing Windows lock restrictions. Supports polling retry to handle asynchronously initializing windows (Fixes #4, credit: @harshbuttru3).

• extra_fs_batch

  High-speed batch filesystem operations avoiding multi-turn shell execution. Complies with Windows Defender Controlled Folder Access (CFA).

• extra_hotkey

  Dispatches a synchronized keyboard shortcut sequence. Example: ['ctrl', 'c'], ['win', 'r'], ['ctrl', 'shift', 'esc'], ['alt', 'tab'].

• extra_indicate_status

  Controls human-agent awareness indicators on the Windows desktop.

• extra_inspect_ui

  Queries Microsoft UI Automation Core v3 to return accessible controls with exact bounding boxes. Allows zero-token semantic targeting without vision hallucinations.

• extra_launch

  Deterministically launches standard Windows applications and tools. Supported shortcuts: 'calc', 'notepad', 'explorer', 'settings', 'cmd', 'terminal', 'edge', 'chrome', 'brave'.

• extra_recall_memory

  Recalls past task execution memories, workflows, generated artifacts, and known app quirks. Uses local embedded KùzuDB and FastEmbed vector search (< 3ms).

• extra_scout_app

  Just-In-Time Application Scout: detects an application's UI framework (Electron, Win32, Viewport), universal hotkeys, CLI automation flags, and scripting APIs before taking GUI actions. Synthesizes a specialized SKILL.md playbook and commits it to active skill directories and memory.

• extra_screenshot

  Captures an ultra-fast screen frame (< 30ms) from the specified monitor. Optionally overlays Set-of-Mark (SoM) numbered badges on all detected interactive UI elements. Saves screenshot to disk to avoid large Base64 payload truncation in AI clients (Fixes #4, credit: @harshbuttru3).

• extra_scroll

  Scrolls the mouse wheel vertically or horizontally. Supports either delta (e.g. -500 or 500) or clicks (e.g. -5, 5 with direction="vertical"|"horizontal"). Positive delta/clicks scrolls up/right, negative scrolls down/left.

• extra_snap_layout

  Arranges multiple windows into a cohesive visual layout in a single programmatic step (sub-15ms). Eliminates fragile multi-turn Win+Left / Win+Right hotkey snapping and avoids Windows 11 Snap Assist popups.

• extra_task_complete

  Signals that the autonomous computer use task is completed. Triggers: 1. The ambient screen edge flashes soft emerald green for ~1.5s, then dissolves. 2. A pleasant multi-harmonic audio chime plays, informing the user immediately even if away from the screen. 3. The cursor beacon dismisses cleanly. 4. Evaluates execution trajectory for friction, stalls, and self-evolution opportunities. 5. Asynchr

• extra_task_start

  Signals the start of an autonomous computer use task. Activates the ambient screen edge pulse (visible to human peripheral vision) and attaches the interactive cursor halo. Automatically initializes episodic memory recording.

• extra_type

  Injects Unicode text with sub-millisecond latency into the active focused window. Uses Win32 KEYEVENTF_UNICODE (VK_PACKET) with 100% fidelity across all scripts and emojis.
