What does mcp-apps-builder do?

mcp-apps-builder is a skill for building, fixing, migrating and checking TypeScript MCP servers and MCP Apps with the mcp-use framework. Claude first inspects package.json, the server entry, views/, skills/ and the installed mcp-use version, which it treats as the source of truth. New projects start from create-mcp-use-app@latest. It then reads only the references the task needs: server tools and resources, React Views, OAuth, Skills over MCP, advanced features, migration and verification. Rules include defining inputSchema and outputSchema, returning raw result envelopes with structuredContent, and keeping identity request-scoped. It will not deploy unless you ask.

When should you use mcp-apps-builder?

Use it when

  • You are scaffolding a new MCP server in TypeScript
  • You want an interactive UI View inside ChatGPT or Claude
  • You are upgrading an old mcp-use project

Skip it when

  • Your MCP server is written in Python
  • You use the official MCP SDK directly
