What it does

Flutter MCP Toolkit Maintain macOS is an agent skill from Arenukvern/mcp_flutter. Maintains showcase/fluttertestapp macOS showcase, native intentcall hooks (codegen, applinks invoke), and VM MCP validation. Use when editing macOS Runner, intentcallcodegen.sh, macOS dogfood, Screen Recording capture, or comparing macOS parity to web WebMCP.

Its SKILL.md is about 670 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, Project scaffolding and MCP servers. It works with macOS, Flutter and Model Context Protocol. 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.

When your agent uses it

  • Editing macOS Runner
  • Intentcallcodegen.sh
  • Screen Recording capture
  • Comparing macOS parity to web WebMCP

Example prompts

  • “Use the flutter-mcp-toolkit-maintain-macos skill to maintain showcase/fluttertestapp macOS showcase, native intentcall hooks (codegen, applinks…”
  • “/flutter-mcp-toolkit-maintain-macos”

What it can do on your machine

Read from SKILL.md and the folder at commit 62f3ee1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • dart
    • make
    • bash

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Flutter MCP Toolkit Maintain macOS loads about 665 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 118 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~665

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.

Maintain macOS (showcase + native intentcall)

Dogfood app: showcase/flutter_test_app. Platform doc: showcase/flutter_test_app/INTENTCALL_PLATFORM.md.

WebMCP on macOS

WebMCP modelContext is web-only. macOS dogfood proves VM extensions, dynamic registry, native invoke (intentcall:// via app_links), and visual capture (Screen Recording on host).

For WebMCP parity scoring, run web iteration separately (flutter-mcp-toolkit-maintain-web).

Launch showcase

bash
make showcase-stop && make showcase
  • Log: .showcase/flutter_app.log
  • WS URI: grep ws://127.0.0.1:…/ws from log (default VM port 8181)
bash
grep -Eo 'ws://127\.0\.0\.1:[0-9]+/[A-Za-z0-9_=-]+/ws' .showcase/flutter_app.log | tail -1

Stop: make showcase-stop.

Codegen & hooks

bash
dart run mcp_server_dart/bin/flutter_mcp_toolkit.dart codegen sync \
  --platform web,android,ios,macos,linux,windows \
  --project-dir showcase/flutter_test_app

dart run mcp_server_dart/bin/flutter_mcp_toolkit.dart init intentcall-platform \
  --project-dir showcase/flutter_test_app --check
TargetRole
macos/intentcall_codegen.shXcode Run Script → codegen sync --platform macos
macos/Runner.xcodeprojRun Script phase (see script comment if manual)
lib/main.dartIntentCallInvokeLinkListener for intentcall://invoke/…

Runtime validate

bash
dart run mcp_server_dart/bin/flutter_mcp_toolkit.dart --save-images \
  --output-dir .showcase/macos_iter validate-runtime \
  --target "$MACOS_WS_URI" \
  --flutter-device macos \
  --timeout-ms 45000

Permissions (host process running CLI):

bash
dart run mcp_server_dart/bin/flutter_mcp_toolkit.dart permissions status
dart run mcp_server_dart/bin/flutter_mcp_toolkit.dart permissions request

Dual-platform dogfood

bash
bash tool/evals/run_dogfood_eval.sh \
