Which MCP Server Should You Choose?
I
Choose Ios Sim MCP when:
You need dedicated capabilities in the Developer Tools domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Ios Sim MCP is categorized under Developer Tools and uses a local stdio subprocess. In contrast, Chrome Devtools MCP belongs to Developer Tools using remote streaming HTTP/SSE transport. Select Ios Sim MCP when you need capabilities focused on developer tools and Chrome Devtools MCP when you require tools for developer tools.
Type 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_text
Byte-perfect text via `UIPasteboard` + first-responder `paste:`. Requires the dylib injected. The right answer for emails, passwords, OAuth tokens, anything case-sensitive
view_tree
Walk 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_start
Install/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_tail
Return 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_body
Fetch 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
