mcp-apps-builder
Load the official MCP Apps builder skills (create-mcp-app, migrate-oai-app, add-app-to-server, convert-web-app) from github.com/modelcontextprotocol/ext-apps. Use when the user says "build an MCP App", "add a ui:// view to my MCP server", "create an interactive MCP App from scratch", "migrate from OpenAI Apps SDK to MCP", or "turn my web app into a hybrid MCP App". Targets the MCP Apps SDK (SEP-1865 ui:// resources) specifically. Not for regular web frontends, REST APIs, CAO provider adapters, SKILL.md authoring, or plugins.
Install
With your agent
Install OMGSkills skill "awslabs/cli-agent-orchestrator:mcp-apps-builder" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.

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.
