mcp-apps-builder
Equip the agent with the official Model Context Protocol "MCP Apps" builder Agent Skills (create-mcp-app, migrate-oai-app, add-app-to-server, convert-web-app) from github.com/modelcontextprotocol/ext-apps. Use whenever building a new MCP App from scratch, adding an interactive ui:// view to an existing MCP server (including a new ui://cao/* view in CAO), migrating an OpenAI Apps SDK app, or turning a web app into a hybrid MCP App. Pairs with cao-mcp-apps (CAO's operator/extend playbook).

MCP Apps Builder (ext-apps Agent Skills bridge) The Model Context Protocol ext-apps repo ships four official Agent Skills that teach an AI coding agent how to build MCP Apps (SEP-1865 — interactive ui:// UIs that render inside a chat host). This skill tells you when to reach for them and how to them, so MCP App work is done with the canonical, up-to-date guidance instead of guesswork. The four builder skills | Skill | Use it when… | |---|---| | create-mcp-app | Scaffolding a new MCP App (server + interactive UI) from scratch. | | add-app-to-server | Adding an interactive ui:// view to an existing MCP server's tools. | | migrate-oai-app | Converting an existing OpenAI Apps SDK app to MCP Apps. | | convert-web-app | Turning an existing web app into a hybrid web + MCP App.
