FlutterSAFE
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
A real-time MCP server providing Flutter/Dart documentation and pub.dev package info to AI assistants — supports ALL 50,000+ packages on demand.
Stop fighting with hallucinated widgets and deprecated APIs. Flutter MCP connects your AI assistant to real-time documentation, ensuring the Flutter code it generates actually works.

The Problem: Your AI is Stuck in 2021
😡 Without Flutter MCP
// User: "How do I use Riverpod to watch a future?"
// AI generates (outdated):
final userProvider = FutureProvider((ref) async {
return fetchUser();
});
// WRONG! Missing autoDispose, family, etc.Result: Deprecation warnings, conf

Questions
What tools does Flutter expose?
8 in total: 8 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is Flutter safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does Flutter need?
It reads FLUTTER_MCP_ACCURATE_TOKENS from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does Flutter run?
It speaks sse and streamable-http, so it runs as a service you connect to over the network. It is published on npm as flutter-mcp at 0.1.2.
How current is this page?
The grade is for one exact copy of the source (0ceefb3e3b5c), read on 2026-10-07. The repository is watched and re-audited when it changes.
