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 3.7.2 or later
• 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: ^0.1.0

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 3.7.2+
• 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 3.7.2+
• 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.
