Rust SDK for the Model Context Protocol (MCP)
⚠️ Warning: This SDK is currently a work in progress and is not ready for production use.
A Rust implementation of the Model Context Protocol (MCP), designed for seamless communication between AI models and their runtime environments.
Add this to your Cargo.toml
:
[dependencies]
mcp_rust_sdk = "0.1.0"
use mcp_rust_sdk::{Client, transport::WebSocketTransport};
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
// Create a WebSocket transport
let transport = WebSocketTransport::new("ws://localhost:8080").await?;
// Create and connect the client
let client = Client::new(transport);
client.connect().await?;
// Make requests
let response = client.request("method_name", Some(params)).await?;
Ok(())
}
use mcp_rust_sdk::{Server, transport::StdioTransport};
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
// Create a stdio transport
let (transport, _) = StdioTransport::new();
// Create and start the server
let server = Server::new(transport);
server.start().await?;
Ok(())
}
The SDK supports multiple transport layers:
The SDK provides comprehensive error handling through the Error
type:
use mcp_rust_sdk::Error;
match result {
Ok(value) => println!("Success: {:?}", value),
Err(Error::Protocol(code, msg)) => println!("Protocol error {}: {}", code, msg),
Err(Error::Transport(e)) => println!("Transport error: {}", e),
Err(e) => println!("Other error: {}", e),
}
