mcp

Overview ¶

Package mcp provides a Go implementation of the Machine Control Protocol (MCP).

The MCP protocol enables bidirectional communication between clients and servers for tool execution, resource access, and prompt handling. This implementation provides a complete framework for building MCP servers and clients.

The package is organized into several sub-packages:

• protocol: Core protocol types and message definitions
• server: Server implementation with session management
• transport: Transport layer implementations (stdio, SSE, WebSocket)

Basic usage example:

func main() {
    // Create a new server
    srv := server.NewServer("Example Server")

    // Add a tool
    srv.AddTool("greet", func(name string) string {
        return "Hello, " + name + "!"
    }, "Greet a person")

    // Create a session
    session := server.NewSession(context.Background(), srv)

    // Create and start a transport
    t := transport.NewStdioTransport(session)
    if err := t.Start(); err != nil {
        log.Fatal(err)
    }
}
