Ios Sim MCP tools 26

  • list_simulatorsList simulators with UDID, state, OS version
  • use_simulatorPick a specific UDID (auto-selected if only one is booted)
  • snapshotCapture the AX tree, assign refs `e1..eN`, return compact text rendering. Filters: `interactive` (default), `actionable`, `all
  • findSearch the snapshot by `id` (AXUniqueId), `label`, `labelContains`, `role`, `actionable
  • tapTap by `{ref}`, `{id}`, or `{x,y}`. Optional `duration` makes it a long-press
  • type_textType into the focused field. Optional `{ref}` or `{id}` taps-then-types. Auto-routes through paste when the dylib is loaded for byte-perfect input — no iOS autocorrect, no first-letter capitalization. `via: "keystroke"` forces the typing path; `via: "paste"` forces the paste path
  • paste_textByte-perfect text via `UIPasteboard` + first-responder `paste:`. Requires the dylib injected. The right answer for emails, passwords, OAuth tokens, anything case-sensitive
  • view_treeWalk the running app's `UIView` hierarchy on the main thread. Reports class names, frames in window coords, alpha/hidden/interactive, text content, and annotates view-controller boundaries. Strictly richer than `snapshot` — sees custom-drawn views, transient overlays, SwiftUI internals. Filter by `…
  • view_hit_test"What view actually receives a tap at (x,y)?" Returns the topmost view plus the full responder chain up to `UIApplication`. The right debugging tool when a `tap` isn't doing what you expect. Requires dylib injected
  • network_startInstall/remove an `URLProtocol` interceptor + swizzle `URLSessionConfiguration` so every `URLSession`-based HTTP request flowing through the app is recorded. Options: `max_records`, `max_body_bytes`, `filter_url_substring`. Requires dylib injected
  • network_tailReturn the most recent N captured records. Default: one line per request (id, method, status, timing, sizes, URL). `full=true` includes headers + body previews inline. Page forward via `since_id
  • network_get_bodyFetch the full request or response body (up to `max_body_bytes`, default 256KB) for a specific record id. Returns base64 + UTF-8 decode for text bodies
