What problem does it solve?

Convert an existing web application into a hybrid MCP App that can render inline in MCP-enabled hosts while preserving standalone behavior.

Core Features & Use Cases

  • Analyze an existing web app and determine the minimal changes needed to support MCP App hosting.
  • Scaffold a server-side wrapper, register a tool and a UI resource, and implement a two-phase build so the UI can run both standalone and as an MCP App.
  • Apply CSP and host-styling integration patterns to ensure consistent appearance and secure operation across hosts.

Quick Start

Outline the steps to convert a given web app into a hybrid MCP App, including environment detection, server wrapper, resource registration, and a two-phase deployment.

FAQPage Schema
How do I convert a web app into a hybrid MCP App?▼

To convert a web app into a hybrid MCP App, you scaffold a server-side wrapper, register a tool and a UI resource, and implement a two-phase build so the UI runs standalone and inline in MCP hosts.

What is a hybrid MCP App and when do I need to wrap my web application?▼

A hybrid MCP App is a wrapped web application that renders inline in MCP-enabled hosts while preserving standalone behavior. You need this to safely integrate existing web UIs into MCP host environments.

Can I use my existing web app build pipeline to run as an MCP App standalone and inline?▼

Yes, the conversion process implements a two-phase build setup that allows the UI resource to run both standalone and as an MCP App within host environments without breaking the existing build pipeline.

Does converting a web app for MCP hosting require CSP and host styling integration?▼

Yes, applying CSP and host-styling integration patterns is required during web app conversion to ensure consistent appearance and secure operation across various MCP-enabled hosts.

What are the limitations when wrapping a web app for MCP host rendering?▼

Limitations include needing frontmatter validation and minimal source changes to support MCP hosting. You must also manage optional resource directories carefully to supply on-demand assets safely.

What is the best way to register UI resources when converting a web app for MCP?▼

The best way to register UI resources during web app conversion is to configure optional resource directories during the server wrapping phase to support and deliver on-demand assets to the MCP host.
