Argent MCP Server

MCP server for iOS Simulator and Android Emulator control

What is the Argent MCP server?

Argent MCP server exists for a simple reason — assistants are far more useful when they can act on Argent directly instead of describing what you should do. MCP server for iOS Simulator and Android Emulator control.

What you get

Argent drives a growing set of targets through a single toolkit, each with the right interaction model - touch, remote or mouse:

  • Record & replay flows — - Capture a sequence of interactions once and let your agent replay it deterministically, so manual repros and smoke tests become repeatable
  • Visual regression — - Diff two screenshots (or a saved baseline against a live capture) with OCR- and font-aware comparison to catch unintended UI changes
  • Debugging and diagnostics — - Let your agent inspect logs, capture network traffic (JS fetch and native), evaluate JS in the running app, walk the native UIKit and React component trees, and reproduce failing states - so you can jump straight to the fix
  • Desktop & web control — - For Electron and Chromium apps your agent can drive tabs, read and write cookies and storage, walk the DOM and inspect network over the Chrome DevTools Protocol
  • React Native out of the box — - Argent works with React Native apps natively, so your agent can build, launch, and iterate on your RN project the same way it would any native app - no extra setup required

What the assistant can call

Once Argent is connected, these are the calls the assistant has available:

  • Platform — Targets
  • iOS — Simulators
  • Android — Emulators (AVDs) and physical devices over adb
  • Editor — Config location
  • Cursor — .cursor/mcp.json (project) or ~/.cursor/mcp.json (global)
  • Windsurf — ~/.codeium/windsurf/mcp_config.json (global)
  • Zed — .zed/settings.json (project) or ~/.config/zed/settings.json (global)
  • Hermes — ~/.hermes/config.yaml (global)
  • opencode — opencode.json (project) or ~/.config/opencode/opencode.json (global)
  • Kiro — .kiro/settings/mcp.json (project) or ~/.kiro/settings/mcp.json (global)
  • Prerequisites — Argent runs Android emulators on Linux but the default install can be slow if a few host-side knobs aren't right. Cover these once and the experience

Setting it up

@swmansion/argent on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Configuration and credentials

  • Node.js 20.12 or later - For iOS / tvOS: macOS with Xcode installed (Apple TV uses tvOS simulators — Xcode downloads the tvOS runtime on demand) - For Android / Android TV: Android SDK Platform Tools (adb) on PATH, and the Android Emulator package if you want to boot AVDs from Argent. Create AVDs via Android Studio or avdmanager. - For Fire TV (Vega): the Vega SDK

Choosing this one

Plenty of monitoring and observability servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Argent's toolset — Platform, iOS, Android and 8 more — is a fair guide to whether it matches your workflow. It is maintained by GitHub Actions; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 11 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Argent.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the argent mcp server does with a few real requests.
