# Migrate OpenAI App to MCP Migrate existing OpenAI Apps SDK applications to the MCP Apps SDK (`@modelcontextprotocol/ext-apps`). The MCP Apps SDK provides a standardized, open protocol for interactive UIs in conversational clients. ## Best Practices - Use your package manager to add dependencies (e.g., `npm install`, `pnpm add`, `yarn add`) instead of manually writing version numbers. This lets the package manager resolve the latest compatible versions. Never specify version numbers from memory. - Preemptively add a final todo item with this exact wording: "Re-read the 'Before Finishing' checklist in this skill and address each checkbox individually, stating what you did for each one, before marking this todo complete." ## Getting Reference Code Clone the SDK repository for complete migration documentation and working examples: ```bash git clone --branch "v$(npm view @modelcontextprotocol/ext-apps version)" --depth 1 https://github.com/modelcontextprotocol/ext-apps.git /tmp/mcp-ext-apps ``` ### Migration Reference Guide Read the migration reference guide with "before/after" mapping tables: `/tmp/mcp-ext-apps/docs/migrate_from_openai_apps.md` ### API Reference (Source Files) Read JSDoc documentation directly from `/tmp/mcp-ext-apps/src/*`: | File | Contents | |------|----------| | `src/app.ts` | `App` class, handlers, lifecycle | | `src/server/index.ts` | `registerAppTool`, `registerAppResource` | | `src/spec.types.ts` | Type definitions | | `src/react/useApp.tsx` ...
