MCPS Transport

Transport layer for MCPS secure communications

MCPS (Model Context Protocol Secure) is "The HTTPS of MCP" - providing enterprise-grade security, encryption, and authentication for Model Context Protocol communications.

Overview

The mcps-transport crate provides the transport layer abstraction for MCPS, including:

• 🔒 Secure Transports - TLS, WebSocket, and custom secure protocols
• 📦 Message Framing - Efficient binary protocol with compression
• 🛡️ Connection Management - Automatic reconnection and health monitoring
• 🔐 Transport Security - Certificate validation and cipher suite management
• 📊 Protocol Negotiation - Automatic transport selection and fallback

Features

• Multi-Protocol Support: TLS, WebSocket, TCP, and custom transports
• Zero-Copy Operations: Efficient message handling with minimal allocations
• Automatic Fallback: Graceful degradation to supported protocols
• Connection Pooling: Efficient connection reuse and management
• Monitoring: Built-in metrics and health checking

Quick Start

use mcps_transport::{Transport, Config, TlsTransport};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Configure secure transport
    let config = Config::builder()
        .endpoint("mcps://server:8443")
        .tls_ca_file("ca.pem")
        .build()?;
    
    // Create transport
    let transport = TlsTransport::new(config);
    
    // Connect and send message
    let mut connection = transport.connect().await?;
    connection.send(b"Hello, MCPS!").await?;
    
    let response = connection.receive().await?;
    println!("Received: {:?}", response);
    
    Ok(())
}

Supported Transports

• TLS: Secure TCP with TLS 1.3 encryption
