What it does

Flutter MCP E2E Harness is an agent skill from Arenukvern/mcp_flutter. Use this skill when writing or running repeatable E2E scenarios for Flutter apps as checked-in Dart with the fluttermcpharness package (packages/harness) — build/launch the app, attach to its VM service, drive widgets (snapshot/tap/enter text) and assert without MCP; also covers the repo showcase launcher (make showcase, --web, --stop) and multi-instance desktop compositions. For interactive assistant-driven debugging through MCP fmt tools, use flutter-mcp instead.

Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile, covering Cross-platform mobile apps, End-to-end testing and MCP servers. It works with Model Context Protocol, Flutter and Dart. The repository describes itself as: MCP Toolkit for Flutter AI Agent Driven Development (MCP/CLI + custom client side tools) - via closed feedback loop (visual & semantic snapshot) and high client side… The licence is MIT.

Context cost

Flutter MCP E2E Harness loads about 2.2k tokens when it runs. Until then it costs about 128 tokens; SKILL.md has 769 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~128
When it runs · the whole SKILL.md, loaded when a task matches: ~2.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: flutter-mcp-e2e-harness
description: Use this skill when writing or running repeatable E2E scenarios for Flutter apps as checked-in Dart with the `flutter_mcp_harness` package (`packages/harness`) — build/launch the app, attach to its VM service, drive widgets (snapshot/tap/enter text) and assert without MCP; also covers the repo showcase launcher (`make showcase`, `--web`, `--stop`) and multi-instance desktop compositions. For interactive assistant-driven debugging through MCP `fmt_*` tools, use `flutter-mcp` instead.

<!-- @FMT_MODE_PRELUDE -->

Flutter MCP E2E Harness

Golden path for programmatic E2E over the toolkit: packages/harness (flutter_mcp_harness) owns the whole lifecycle — build the app, launch the process, attach to its Dart VM service, and only then drive/assert. It speaks the same ext.mcp.toolkit.* service extensions as the MCP server, as plain Dart. ADR: decisions/0015_flutter_mcp_harness_extraction.mdx.

The driving layer speaks the universal AutomationDriver contract (ADR-0038, universal_automation_interface): ToolkitDriver exposes the observe/act/verify loop (snapshot → semantic AxNode tree with refs and bounds; perform click/type/key/named-route-navigate/evaluate; screenshot PNG), so the same agent vocabulary drives Flutter apps, browsers (CdpDriver), and OS-native targets. IntentDriverRouter additionally routes an intent's automation hint (transport + verb + locator) onto the bound driver. Frame pipelines are deliberately NOT a harness dependency — they are composition-level (showcase/drivers, which also holds the live end-to-end drives: make drive-flutter / drive-flutter-chrome / drive-web).

App-specific verbs use the invoke tier (ADR-0017): the app's intent registry IS the action catalog — driver.actions() lists it, and InvokeAction(name, args) dispatches to a registered entry with schema-validated arguments (custom IntentAutomationAction.custom hints route the same way). Web surfaces without a VM service (Jaspr, plain JS) compose identically over CdpDriver via the window.__mcpActions page registry.

Need	Use
Repeatable scenario as code, CI-friendly exit codes	this skill (`flutter_mcp_harness`)
One-off interactive debugging from chat/editor	`flutter-mcp` (MCP `fmt_*` tools)
Browser/WebMCP dogfood of the web showcase	`flutter-mcp-toolkit-maintain-web`
Live end-to-end showcase drives (both tiers)	`showcase/drivers` (`make drive-flutter` / `drive-web`)

Launch paths (pick by ownership)

The #1 rule: at most one owning session per app. A second flutter run/flutter attach on a session someone else owns is the ADR-0014 failure mode (the second attach can kill the first).

Target	When	Notes
`FlutterRunTarget`	You want the flutter tool to own build + hot reload (`r`/`R`/`q` via stdin). The showcase launch path.	`device` (`macos`, `chrome`, …), `extraArgs`, `onLine` tee for long cold builds; VM URI scraped from the tool's own announcement.
`BinaryAppTarget` / `MacosAppTarget` / `WindowsAppTarget`	Fresh full `flutter build <os> --debug` → launch the binary directly. No compile channel afterwards.	Pass `launch(build: false)` to reuse an existing binary. Never opens an owning session.
External runner (e.g. `oka dev`) owns the app	Construct `LaunchedApp` directly around the owning process and read the VM URI from the runner-session contract, not stdout.	This package never imports the runner; callers wire it (`LaunchedApp(name:, process:, stdout:, vmUri:)`).

FlutterRunTarget.launch(build:) ignores the flag — flutter run always builds. A failed bring-up reaps the session (SIGTERM → child-reaping pkill → SIGKILL) before rethrowing.

Scenario anatomy

dart

final scenario = Scenario('checkout E2E', steps: [
  ('launch app', (context) async {
    final app = await MacosAppTarget(projectDir: appDir, binaryPath: binary)
        .launch(build: build);
    launched = app;                       // for finally-stop
    await app.stdout.waitFor('app ready'); // no sleeps — wait on logs
    context.bag['app'] = app;             // hand values between steps
  }),
  ('drive + assert', (context) async {
    final driver = WidgetDriver(await context.take<LaunchedApp>('app').vm());
    final ref = await driver.findRef('checkout');
    if (ref == null) return context.report.fail('no checkout button');
    await driver.tap(ref);
    final total = await driver.findValue((v) => v.startsWith(r'$'));
    total != null
        ? context.report.pass('total rendered: $total')
        : context.report.fail('no total in snapshot');
  }),
]);

var passed = false;
try {
  passed = await scenario.run();
  scenario.report.printSummary();
} finally {
  await launched?.stop();                 // cleanup always runs
}
exit(passed ? 0 : 1);

Steps run in order; first failure (thrown or report.fail) aborts the rest — cleanup still happens in the caller's finally.
HarnessContext.bag passes values between steps; take<T>(key) reads them.
retry(action) polls until non-null (for app-side readiness races).
Full two-instance composition root: packages/harness/example/desktop_pair.dart.

Driving widgets (`WidgetDriver`)

snapshot() → (label, ref) pairs; findRef(needle) is case-insensitive substring + retry until timeout.
tap(ref), tapUntil(ref, until: …) (re-tap until a predicate fires), enterText(ref, text), scroll(direction:, distance:) — off-screen semantics only exist once scrolled into view.
findValue(predicate) reads a node's selectable-text value — the deterministic way to read app-rendered data (clipboards and icon-only copy buttons are not).
Cold-attach race: the app may not have registered the toolkit yet when you attach. The driver answers RPC error -32601 with an empty snapshot so findRef's retry loop rides it out instead of aborting — do not treat one empty snapshot as proof the UI is empty.
VmClient extras: extensionNames() (discoverability), evaluate(expr), hotReload(). Raw reloadSources cannot compile without an owning flutter run/attach session — treat true as "asked", not "recompiled".

Showcase launcher (`packages/harness/tool/showcase.dart`)

bash

make showcase        # macOS showcase, interactive foreground (r/R/q relayed)
make web-showcase    # Chrome + WebMCP flags; WEB_PORT/VM_HOST_PORT/FLIGHT… env
make showcase-stop   # kill stray sessions, free VM port 8181 (idempotent)

--web --detach (or make-less dart run packages/harness/tool/showcase.dart --web --detach) spawns headless-ish, waits for the ws:// VM URI in .showcase/web_app.log, prints WS_URI=…, exits 0 — the CI-friendly variant.
Artifacts under .showcase/: flutter_app.log / web_app.log (teed output) and flutter.pid / web_flutter.pid pid files.
IntentCall doors (second terminal, against the running showcase): dart run packages/harness/tool/intentcall_session.dart [demo|serve-link|serve-debug] — resolves the VM service URI from the showcase log (--vm-service-uri pins one) and the IntentCall CLI from INTENTCALL_ROOT, sibling checkouts, or PATH.
Interactive mode tees every line to the log (which make exec-sweep greps) and tears the session down on exit or Ctrl-C.
WS URI for follow-up calls: grep -Eo 'ws://127\.0\.0\.1:[0-9]+/[A-Za-z0-9_=-]+/ws' .showcase/flutter_app.log | tail -1.

Hard boundaries

No new toolkit verbs. ToolkitExtensions mirrors mcp_toolkit/lib/src/toolkits/interaction_toolkit.dart; keep the lists in lockstep — drift is caught by extension calls failing at runtime today (shared-constants follow-up will make it a compile error).
No owned compile sessions in BinaryAppTarget — full fresh builds only.
No declarative scenario documents (YAML runners) — the external flutter_harness experiment (ADR-0012) is retired (ADR-0017). Composition roots are consuming-project code (see example/).
Android/iOS device bring-up is delegated to the owning dev session (oka_harness, ADR-0014) — not this package.

Verify

bash

cd packages/harness && dart test        # unit tests (canned envelopes, fake flutter)
dart run example/desktop_pair.dart --skip-build

flutter-mcp — the interactive MCP loop over the same extensions
flutter-mcp-automation-chain — cross-tier wiring for your own app (surface picker, oka integration, runner sessions)
flutter-mcp-toolkit-maintain-macos / -maintain-web — showcase + platform lanes
packages/harness/README.md, ADR-0014 (runner delegation), ADR-0015 (extraction)
