+Connect Hono with a Model Context Protocol (MCP) server over HTTP Streaming Transport.

+## Usage

+```ts
+import { McpServer } from '@modelcontextprotocol/sdk/server/mcp.js'
+import { StreamableHTTPTransport } from '@hono/mcp'
+import { Hono } from 'hono'
+
+const app = new Hono()
+
+// Your MCP server implementation
+const mcpServer = new McpServer({

+  version: '1.0.0',
+})
+
+app.all('/mcp', async (c) => {
+  const transport = new StreamableHTTPTransport()
+  await mcpServer.connect(transport)
+  return transport.handleRequest(c)
+})
