Warp integration for the Rust MCP SDK.

This crate provides integration between the MCP SDK and the Warp 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 via Warp filters

Quick Start

use mcpkit::prelude::*;
use mcpkit_warp::McpRouter;

// Your MCP server handler (use #[mcp_server] macro)
#[mcp_server(name = "my-server", version = "1.0.0")]
impl MyServer {
    #[tool(description = "Say hello")]
    async fn hello(&self, name: String) -> ToolOutput {
        ToolOutput::text(format!("Hello, {name}!"))
    }
}

#[tokio::main]
async fn main() {
    McpRouter::new(MyServer::new())
        .serve(([0, 0, 0, 0], 3000))
        .await;
}

mcpkit-warp

Warp framework integration for mcpkit MCP servers.

Features

• Full MCP protocol support over HTTP
• Filter-based architecture
• CORS support with configurable origins
• Session management with SSE streaming

Usage

use mcpkit_warp::McpRouter;

#[tokio::main]
async fn main() {
    let handler = MyHandler::new();
    let router = McpRouter::new(handler).with_cors();

    // Serve with CORS
    warp::serve(router.into_filter())
        .run(([0, 0, 0, 0], 3000))
        .await;
}

Requirements

• Rust 1.85+
• Warp 0.3+
