+# @modelcontextprotocol/ext-apps
+
+MCP Extensions Apps SDK.
+
+## Installation
+
+This repo is in flux and isn't published to npm (when it is, we'll probably use the `@modelcontextprotocol/ext-apps` package). Please install it from git for now:
+
+```bash
+npm install git+https://github.com/modelcontextprotocol/ext-apps.git
+```
+
+## Development Notes
+
+### Build tools in dependencies
+
+The build tools (`esbuild`, `tsx`, `typescript`) are in `dependencies` rather than `devDependencies`. This is intentional: it allows the `prepare` script to run when the package is installed from git, since npm doesn't install devDependencies for git dependencies.
+
+Once the package is published to npm with pre-built `dist/`, these can be moved back to `devDependencies`.
