Axum integration for the Rust MCP SDK.

This crate provides integration between the MCP SDK and the Axum web framework, making it easy to expose MCP servers over HTTP.

Features

HTTP POST endpoint for JSON-RPC messages
Server-Sent Events (SSE) streaming for notifications
Session management with automatic cleanup
Protocol version validation
CORS support

Example

use mcpkit_axum::{McpRouter, McpState};
use mcpkit_server::ServerHandler;
use axum::Router;

// Your MCP server handler (must implement ServerHandler)
struct MyServer;

#[tokio::main]
async fn main() {
    // Create MCP router with your handler
    let mcp_router = McpRouter::new(MyServer);

    // Build the full application
    let app = Router::new()
        .nest("/mcp", mcp_router.into_router());

    // Run the server
    let listener = tokio::net::TcpListener::bind("0.0.0.0:3000").await.unwrap();
    axum::serve(listener, app).await.unwrap();
}
