An empty string is distinct from absent text (`present: false`). +- **Image.** The preview is oriented, with separate source and preview metadata. A large preview may flatten transparency onto a white JPEG. +- **Files.** It returns up to 32 advertised local file URLs and their decoded paths. It neither opens the files nor confirms they exist. +- **Refused.** Text and image reads need exactly one clipboard item. File promises, legacy-only filename lists, items mixing files with other content, and unreadable or oversized content are refused. +- **Side effects.** It needs macOS to allow clipboard reading. It never changes the clipboard or releases a pending paste reservation. + +**`desktop_clipboard_write`.** +- **Image.** Its original bytes, orientation and transparency are kept. It may be at most 10 MiB and 64 million pixels. +- **Files.** Each path must be an existing file, folder or symbolic link. The check reads only metadata, not contents, and doesn't resolve links. References keep their order and duplicates within the 24 KB read-result limit. `file_count` counts the references requested, not what a receiver copies or pastes. +- **Persistence.** The write lasts until the next copy or write. + +**`desktop_launch` and `desktop_open`.** +- **Choosing a copy.** A bundle ID lets macOS choose the installation; a path selects one copy. One launch can include several counted activation attempts. +- **`desktop_open` limits.** Items are at most 4096 UTF-16 units, and the whole request at most 16 KiB. Paths keep Unicode and spaces, with no shell expansion. URLs must already be encoded and are never repaired. Any scheme, including `file` and custom schemes, has its receiving app's normal effects. +- **Neither tool** batches items, creates extra instances or handles dialogs. + +**`desktop_menus` and `desktop_menu`.** +- **Reading.** A read is bound to the same process generation before and after. Native results can come from a 2-second cache, so their time and completeness, including lazy or budget-limited submenus, are unknown. Result truncation is counted separately (`truncated`, `omitted`). Enabled and checked state are left out, because the native service substitutes defaults for attributes it can't read. Paths are for discovery, not reusable action targets. Accessibility reads are synchronous and can delay cancellation. +- **Running a command.** `desktop_menu` resolves the path afresh. It refuses missing, ambiguous, disabled or unavailable lazy paths, and presses only the final item once. Its reads and the press run off the GUI actor, with a finite messaging timeout. Cancellation waits for the native call to return and can't undo delivered input. + +**`desktop_menubar_click`.** Before pressing, the host lists the menu bar again. It refuses if the item at that index no longer has the same owner generation, identifier, title, bounds or neighbours. Where an item has its own window, it is clicked through that window. The result lists the windows that appeared within about a second, front to back, with pid, window ID, owner, layer and bounds. It captures their region as an image without a snapshot. + +**`desktop_dock`.** Titles match exactly, including case, punctuation and Unicode. The right-click menu's submenus can't be reached. + +**`desktop_quit` and `desktop_close`.** A normal quit or close can open an unsaved-work dialog. The result is then `unknown`, with fresh inventory when available. The host never retries, force-closes or answers the dialog. `force: true` terminates that exact process immediately, with no save prompt. + +**`desktop_inspect`.** +- **Accessibility mode** (the default) can return an action snapshot with element IDs. +- **Pixels mode** returns a snapshot with no element IDs and no focused control. It authorizes only point clicks, point scrolls and drags in that exact window. +- **After an action,** the automatic observation uses accessibility mode. If it fails, inspect again with pixels mode. + +**`desktop_click`.** A single left click on a supported editable text field, by element or point, also requests keyboard focus. The result says whether focus was verified; use `desktop_select` to choose a range or caret position. Points stay bound to the captured window, even when the returned screenshot was scaled. + +**`desktop_scroll`.** `amount` is in native scroll units. Their distance depends on the route the target supports, not on pixels. + +**`desktop_set_value`.** +- **Dates.** A date is written as the control's date value and must read back to the second. The result shows it in UTC. A control that drops the time or seconds reports `unknown`. If a date control refuses, the result's `keyboard_route` explains entering it field by field. +- **Toggles.** A toggle whose value is read-only but which advertises `AXPress` gets at most one press, and none when it already has the requested state. +- **Pop-up buttons.** To pick an item, use `desktop_element_action` with `AXPick`, or `desktop_click`, on the item from the fresh observation. + +**`desktop_insert`, paste route.** +- **Requirements.** The field's text and selection must be readable, and macOS must allow clipboard reading so the earlier contents can be restored. The original and resulting values must each fit 65,536 UTF-16 units. +- **Delivery.** The paste is bound to the exact process, window and focused control. An exact receiver in the active frontmost app gets the paste chord directly. Any other target first gets a guarded click on a blank part of its title bar, which keeps the editor and selection; unsupported window chrome is refused. The route never changes after input begins, and the app isn't brought forward. +- **Clipboard.** The clipboard is restored only after a meaningful observed edit. After uncertain delivery, the replacement may stay on the clipboard, and anything copied since is kept. The result reports delivery separately from `consumption`, `clipboard_cleanup` and `clipboard_ownership`. +- **Reservation.** A reserved ownership refuses later automated clipboard writes until the edit is verified or the receiving process exits. Restarting the host doesn't clear it. + ## Not supported - **Confirmed insertion outside text fields.** Where `desktop_insert` can't observe a text control with a readable selection, such as terminals, canvases and custom views, it types the text instead, and the result is `unknown`, because nothing can read back what the receiver did with it. Typed insertion can't contain newlines or tabs. diff --git a/src/mcp.ts b/src/mcp.ts index fea57d95..97bb0873 100644 --- a/src/mcp.ts +++ b/src/mcp.ts @@ -7,7 +7,7 @@ import { parseArgs } from "node:util"; import { type DesktopConfig, createDesktop } from "./client.js"; import { type DesktopRequest, isDesktopAction } from "./protocol.js"; -import { type DesktopTool, desktopRequest, desktopTools } from "./tools.js"; +import { type DesktopTool, desktopRequest, desktopToolRules, desktopTools } from "./tools.js"; const { values } = parseArgs({ options: { client: { type: "string" }, socket: { type: "string" }, name: { type: "string" } }, @@ -29,7 +29,7 @@ const { version } = JSON.parse( // Newest first; an unsupported client version gets the newest, as the MCP lifecycle requires. const VERSIONS = ["2025-11-25", "2025-06-18", "2025-03-26", "2024-11-05"]; -// Guidance mirrors Ace's desktop extension so agents behave alike; tools come from the shared definitions. +// Guidance mirrors Ace's desktop extension so agents behave alike; tools and their shared rules come from the shared definitions. const instructions = [ `Use desktop_* tools to observe and operate native apps on this Mac through ${host}, which holds the macOS permissions.`, "Shell commands remain appropriate for builds, files, and preparing clipboard fixtures directly.", @@ -43,6 +43,8 @@ const instructions = [ "Action results start with their outcome: completed, refused, or unknown.", "For a refusal before dispatch, follow its concrete recovery hint once when applicable, then refresh the observation; a refusal alone does not prove the capability is missing.", "After completed, interrupted, or uncertain input, inspect the current target before deciding whether another action is needed.
