mcp-apps is a Claude Code plugin that provides skills for building MCP Apps using the MCP Apps SDK, according to the project README. It is installed through Claude Code's plugin marketplace by adding the modelcontextprotocol/ext-apps repository and installing mcp-apps@modelcontextprotocol-ext-apps. The plugin offers two sets of invokable skills: one for creating a new MCP App (adding a UI to an MCP tool or scaffolding an interactive MCP View), and one for migrating an existing app from the OpenAI Apps SDK to MCP. Per the MCP homepage, the underlying Model Context Protocol (MCP) is an open-source standard for connecting AI applications to external data sources, tools, and workflows.
Overview
This is not a SaaS product but a Claude Code plugin (extension). It builds on the Model Context Protocol (MCP), an open standard described on the MCP homepage for connecting AI applications to external systems, and per the README it supplies skills for creating and migrating MCP Apps — interactive applications that run inside MCP-compatible AI clients — using the MCP Apps SDK.
