MCP SSE Proxy Module

This module provides a proxy implementation for MCP (Model Context Protocol) using SSE (Server-Sent Events) transport.

Features

• SSE Support: Uses rmcp 0.10 with SSE transport (removed in 0.12+)
• Stable Protocol: Production-ready SSE implementation
• Hot Swap: Supports backend connection replacement
• Fallback Option: Used when Streamable HTTP is not supported
• High-level Client API: Simple connection interface hiding transport details

Architecture

Client → SSE → SseHandler → Backend MCP Service

Example

use mcp_sse_proxy::{SseClientConnection, McpClientConfig};

// Connect to an MCP server
let config = McpClientConfig::new("http://localhost:8080/sse");
let conn = SseClientConnection::connect(config).await?;

// List available tools
let tools = conn.list_tools().await?;
