simdrive 1.0.0b14

Reproduce and validate iOS bugs in 60 seconds with Claude.

SimDrive is the MCP-native iOS automation toolkit your AI agent already knows how to drive. Hand it a Linear ticket, watch it walk the steps in the simulator (or a paired real device), and get back a deterministic recording that replays the same way every time.

60-second bug repro

You (in Cursor / Claude Code):
  "Use simdrive to reproduce Linear ENG-1247 — sign-in fails on iPhone 17 /
   iOS 26.3 with test@example.com."

Claude:
  → session_start({device: "iPhone 17", os_version: "26.3", bundle_id: "com.acme.app"})
  → observe()                              # screenshot + annotated marks
  → tap({text: "Email"})
  → type_text({text: "test@example.com"})
  → tap({text: "Password"})
  → type_text({text: "pw123"})
  → tap({text: "Sign In"})
  → observe()                              # captures error toast
  → record_stop({name: "ENG-1247-repro"})  # YAML+PNG attached to PR

After you ship the fix, replay the same recording with the replay tool to confirm it still fails (or now passes) before deploy.

What you get

• Bug reproduction + validation (hero) — agent reads the ticket, drives the simulator, captures the failure, saves a deterministic recording.
• Record → replay — recordings are YAML + PNG bundles that re-run identically each time via the replay tool.
• Autonomous test suites — run_journey reads a YAML journey with goals and success criteria; SimDrive drives the agent loop and reports pass/fail with evidence.
• Real iOS device support — WebDriverAgent-backed; one-command simdrive bootstrap-device <udid> bring-up.
• Visual regression detection — SSIM-based pre/post comparison with configurable drift handling.
• Performance baselines + regression comparison — capture CPU / RSS / thread baselines and diff future runs.

Install

pip install simdrive

No license or account required.

Requires: macOS, Xcode 15+, Python 3.10+.

Wire SimDrive into your MCP client

Add to .claude/mcp.json (Claude Code), claude_desktop_config.json (Claude Desktop), or your Cursor MCP config:

{
  "mcpServers": {
    "simdrive": { "command": "simdrive" }
  }
}

Restart the client. Your agent now has 36 SimDrive tools available.

Note: SimDrive is no longer offered as a commercial product. It remains available as a free, open MCP tool for internal/personal use — see LICENSE.

Minimum-viable session

session_start(bundle_id="com.example.app")
observe()                                  # see initial screen
tap(label="Sign In")                       # tap a labelled control
observe()                                  # verify state
record_stop(session_id="...", name="signin-smoke")   # save replay
session_end(session_id="...")              # clean up

Tool surface (36 MCP tools)

Real-device support

Drive a paired iPhone or iPad in addition to the simulator:

export SIMDRIVE_ALLOW_PHYSICAL_DEVICE=1
simdrive bootstrap-device <device-udid>

session_start(bundle_id="com.example.app", udid="<device-udid>", target="device")

WDA bootstrap on iOS 26.x has some rough edges; the simulator (target="simulator", default) is the fully supported path.

Known limitations

See docs/LIMITATIONS.md for: type_text first-character drop workaround, SSIM-vs-structural-check semantics, SwiftUI half-sheet dismissal, appearance-respring caveats, real-device input scope.
