flutter-mcp-toolkit-maintain-macosMaintains showcase/fluttertestapp macOS showcase, native intentcall hooks (codegen, applinks invoke), and VM MCP validation.
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.
Read from SKILL.md and the folder at commit 62f3ee1. It shows what the files ask for, not the result of running them.
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.
Shell commands in SKILL.md call:
dartmakebashFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
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.
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.
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.

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).

Going by SKILL.md and its folder, Flutter MCP Toolkit Maintain macOS needs the command-line tools its instructions call (dart, make and bash).
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Flutter MCP Toolkit Maintain macOS is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 665 tokens (SKILL.md is roughly 2.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
