DartMCP

A Dart implementation of the Model Context Protocol (MCP) for AI agent interactions.

Overview

DartMCP is a Model Context Protocol (MCP) implementation in Dart, providing both server and client components for building interoperable AI/LLM tools and services.

Requirements

• Dart SDK 3.9.2+
• Works on any platform supported by Dart (macOS, Linux, Windows)

Project Structure

The project is organized into two main components:

• `lib/src/server.dart`: The server implementation
• `lib/src/client.dart`: The client implementation

Dependencies

• MCP Dart SDK

Installation

1. Add DartMCP to your project:

dependencies:
  dart_mcp: ^0.3.3

2. Install dependencies:

dart pub get

Server

The DartMCP server component provides a Model Context Protocol server implementation in Dart. It enables AI agents and tools to interact with Dart applications using the standard MCP protocol.

Features

• Built with Dart 3.9.2+
• Implements MCP protocol over standard I/O or custom channels
• Includes support for logging, prompts, resources, and tools
• Cross-platform support

Getting Started

1. Implement your server logic using `Server` from `lib/src/server.dart`.

2. Run your server as a Dart application:

dart run path/to/your_server.dart

Server Component Details

The server component is responsible for:

• Handling incoming MCP connections
• Managing model context and state
• Processing client requests
• Maintaining state synchronization

Location: `lib/src/server.dart`

Client

The DartMCP client component allows Dart applications to connect to and interact with MCP-compatible AI agents and servers.

Features

• Built with Dart 3.9.2+
• Implements MCP client over standard I/O or custom channels
• Simple API for initializing and communicating with MCP servers
• Streams for server notifications (tools, resources, logs, etc.)

Getting Started

1. Use the `Client` class from `lib/src/client.dart` in your Dart application.

2. Example usage:

import 'package:dartmcp/dartmcp.dart';

void main() {
  var client = Client();
  client.main();
}

Client Component Details

The client component provides:

• Connection management to MCP servers
• Model context synchronization
• Real-time updates handling
• Client-side state management

Location: `lib/src/client.dart`

Example

See `example/dartmcp_example.dart` for a minimal usage example.
