THEN When using @modelcontextprotocol/sdk v1.25.x with Next.js App Router, pass { overrideGlobalObjects: false } to getRequestListener() to prevent hono from overwriting global.Response. Alternatively, use webStandardStreamableHTTPServerTransport if available.

// Instead of default instantiation:
const transport = new StreamableHTTPServerTransport({ ... });
transport.getRequestListener(); // implicit overrideGlobalObjects: true

// Fix:
transport.getRequestListener({ overrideGlobalObjects: false });
