ERIUS PHONE vs Ios Sim MCP
A side-by-side look at the ERIUS PHONE and Ios Sim MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose ERIUS PHONE for os automation work as a local process; choose Ios Sim MCP for os automation as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose ERIUS PHONE when
- You need dedicated capabilities in the OS Automation domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
ERIUS_PHONE_API_KEY, ERIUS_PHONE_DEFAULT_DEVICE, ERIUS_PHONE_API_URL, ERIUS_PHONE_TIMEOUT. - You want tools like
list_devices, whoami, get_device.
Choose Ios Sim MCP when
- You need dedicated capabilities in the OS Automation domain.
- You prefer a local stdio subprocess transport.
- You want tools like
list_simulators, use_simulator, snapshot.

Tools & capabilities
ERIUS PHONE tools 21
list_devicesList every Android device your API key can access, with live status (booted, Android version, screen size). Call this first to get device ids.whoamiShow which ERIUS PHONE account (tenant) and key id this server is using, and the device ids it can access. Handy to check the API key works.get_deviceGet full status of one device: boot state, Android version, screen size, and the app currently in the foreground. Omit `device` to use the default.snapshotGet an accessibility-tree snapshot of the current screen: every visible element with its text, role, and a `ref` id you can pass to tap/type/scroll. This is how the agent 'sees' the phone — read it before acting, and take a fresh one after any action since refs reset on every snapshot.screenshotTake a screenshot of the device screen right now and return it as an image you can look at, plus one line of text with the image size and the device's real screen size. The default is a JPEG whose longest side is 1024 px (tens of KB). A full-size PNG of a 1440x3120 phone is about 3 MB, which is more than many MCP clients accept in a tool result, so ask for it only when you need it: format="png", max_side=None. `format` is "jpeg", "webp" or "png"; `quality` is 1-100 (jpeg/webp); `max_side` caps the longest side in pixels (64-8192); `scale` (0.1-1) shrinks by a factor instead. When the image is smaller than the screen, pass its size as image_width/image_height to tap(), long_press() or swipe() so x,y are read in the image's pixels. Prefer snapshot() when you only need text and refs: it's far smaller.foregroundGet just the foreground app: package, activity, and whether a crash dialog is showing. Cheaper than a full snapshot when you only need this.tapTap an element. Prefer `ref` from a snapshot(), or `text`/`content_desc` to tap by visible label. Falls back to raw `x`,`y` pixel coordinates: in device pixels, or, with `image_width` and `image_height`, in the pixels of a screenshot of that size (the API maps the point to the screen).long_pressLong-press an element (e.g. to open a context menu or start a drag). Targets work like tap(): `ref`, `text`/`content_desc`, or raw `x`,`y` (with `image_width`/`image_height` when they come from a scaled screenshot). `ms` (hold time, default 800) only applies to the x,y form.type_textType text into a field. Optionally tap a `ref` or `text_target` label first to focus the field, `clear` the existing value, or press Enter after. Keystrokes sent while the field is still opening are lost, so if tapping the field opens a new screen (e.g. a search page), tap it first, wait for it with snapshot() or wait_for_text(), then type with no target. Check the result with snapshot(). Only printable ASCII is supported (adb limitation).press_keyPress a hardware/navigation key: back, home, enter, delete, tab, escape, up, down, left, right, space, power, volup, voldown, recent, menu, wakeup.swipeSwipe from one point to another: in device pixel coordinates, or, with `image_width` and `image_height`, in the pixels of a screenshot of that size.scrollScroll a list/container up, down, left, or right. `ref` must be the ref of the scrollable container itself (a ScrollView or List line in the snapshot), not of a row inside it: scrolling a single row does nothing. If the container has no ref, use swipe() instead.- +9 more on the listing page

list_simulatorsList simulators with UDID, state, OS versionuse_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`, `allfindSearch the snapshot by `id` (AXUniqueId), `label`, `labelContains`, `role`, `actionabletapTap by `{ref}`, `{id}`, or `{x,y}`. Optional `duration` makes it a long-presstype_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 pathpaste_textByte-perfect text via `UIPasteboard` + first-responder `paste:`. Requires the dylib injected. The right answer for emails, passwords, OAuth tokens, anything case-sensitiveview_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 injectednetwork_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 injectednetwork_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_idnetwork_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- +14 more on the listing page

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
ERIUS PHONE has no declared pricing — check the project's own site. Ios Sim MCP has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add erius-phone and ios-sim-mcp as separate keys in the same mcpServers object, and your assistant will call tools from either one.
