# dart_mcp A Dart implementation of the Model Context Protocol (MCP). ## Features - Full implementation of the MCP specification - Support for both client and server roles - Built-in stdio transport layer - Type-safe API with JSON serialization - Comprehensive test coverage ## Installation Add this to your package's `pubspec.yaml` file: ```yaml dependencies: dart_mcp: ^1.0.0 ``` ## Usage ### Client Example ```dart import 'package:dart_mcp/dart_mcp.dart'; void main() async { // Create a transport for the client final transport = StdioTransport(); // Create a client with basic capabilities final client = McpClient(transport); try { // Initialize the client final result = await client.initialize( capabilities: ClientCapabilities( sampling: SamplingCapability(), ), clientInfo: Implementation( name: 'example-client', version: '1.0.0', ), ); print('Connected to server: ${result.serverInfo.name} ${result.serverInfo.version}'); print('Server capabilities: ${result.capabilities}'); // Send a ping request await client.sendRequest('ping'); print('Ping successful'); } catch (e) { print('Error: $e'); } finally { await client.close(); } } ``` ### Server Example ```dart import 'package:dart_mcp/dart_mcp.dart'; void main() async { // Create a transport for the server final transport = StdioTransport(); // Create a server with capabilities final server = McpServer( transport: transport, capabilities: ServerCapabilities( tools: ToolsCapability(), resources: ResourcesCapability(), ), serverInfo: Implementation( name: 'example-server', version: '1.0.0', ), ); // Register request handlers server.onRequest('ping', (params) async { return EmptyResult(); }); // Handle client notifications server.onNotification('notifications/initialized', (params) { print('Client initialized'); }); } ``` ## Features and bugs Please file feature requests and bugs at the [issue tracker](https://github.com/yourusername/dart_mcp/issues). ## License MIT License - see LICENSE file for details.
