Flutter MCP Client — a Claude AI desktop interface built with Flutter, following Clean Architecture principles and powered by a modular monorepo using Melos. This application demonstrates the implementation of the Model Context Protocol (MCP) for rich AI-driven interactions.

🧰 Features

• 🖥️ Desktop-first Flutter app
• 🧼 Clean Architecture with modular monorepo
• 📦 State management using Flutter Bloc
• 🔌 MCP client/server implementation for interacting with Gemini
• 💬 Chat interface with real-time stream updates
• ⚙️ Add, edit, and manage MCP servers
• 🧠 Built-in AI and function-calling support
• 🎨 Custom widgets and clean UI

📁 Project Structure

This repository is organized using the monorepo approach with Melos:

apps/               # Main Flutter applications
external/           # External SDKs or libraries (e.g., LLM Kit)
packages/           # Feature-specific packages (Clean Architecture layers)

Key Layers

• flutter_mcp_entities: Data models for AI, Chat, and MCP
• flutter_mcp_datasources: Local and remote data handling
• flutter_mcp_repositories: Repositories for dependency injection
• flutter_mcp_usecases: Use cases implementing core logic
• flutter_mcp_state: BLoC/Cubit state management
• flutter_mcp_widgets: Custom reusable UI components

🚀 Getting Started

Prerequisites

Ensure the following tools are installed:

• Flutter SDK

• Dart SDK

• Melos (Monorepo manager):

  dart pub global activate melos
  

Installation

# Clone the repository
git clone https://github.com/your-org/flutter_mcp.git
cd flutter_mcp

# Bootstrap all packages
melos bootstrap

flutter run -d linux

🧪 Running Tests

melos run test

🔍 Packages Overview

Each package in packages/ encapsulates a specific layer or feature:

Package	Description
flutter_mcp_entities	Domain models and entities
flutter_mcp_datasources	Local persistence and data sources
flutter_mcp_repositories	Abstraction layer for domain repositories
flutter_mcp_usecases	Business logic and user interactions
flutter_mcp_state	Cubit/Bloc-based state management
flutter_mcp_widgets	Custom UI components

🎨 UI & UX

• Utilizes fonts like Copernicus and StyreneB
• Responsive layouts and custom theming
• Reusable form fields, chat bubbles, connection indicators

📡 MCP Protocol Support

This app implements an MCP (Model Context Protocol) client, enabling AI interactions through structured messages, tool calling, and content embedding.

Supported features include:

• Streaming chat updates
• Tool registration and invocation
• Embedded content handling (text, images, resources)
• Connection lifecycle management
