+# Authenticated MCP server (Python)
+
+This example shows how to build an authenticated app with the OpenAI Apps SDK.
+It demonstrates triggering the ChatGPT authentication UI by responding with MCP
+authorization metadata and follows the same OAuth flow described in the [MCP
+authorization spec](https://modelcontextprotocol.io/docs/tutorials/security/authorization#the-authorization-flow:-step-by-step).
+
+The Apps SDK [auth guide](https://developers.openai.com/apps-sdk/build/auth#triggering-authentication-ui) covers how the UI is triggered.
+
+The server exposes two tools:
+
+1. `search_pizza_sf` (mixed auth, returns the `mixed-auth-search` widget)
+2. `see_past_orders` (OAuth required, returns the `mixed-auth-past-orders` widget with past orders data)
+
+If a request is missing a token for the protected tool, the server returns an `mcp/www_authenticate` hint (backed by `WWW-Authenticate`) plus `/.well-known/oauth-protected-resource` metadata so ChatGPT knows which authorization server to use. With a valid token, the tools return widget markup or structured results.
+
+## Set up
+
+### 1. Configure the authorization server (Auth0)
+
+> This example uses an Auth0 tenant as a default authorization server. To set up your own, follow the instructions below:
+
+1. **Create an API**
+
+   - Auth0 Dashboard → _Applications_ → _APIs_ → _Create API_
+   - Name it (e.g., `mcp-python-server`)
+   - Identifier → `https://your-domain.example.com/mcp` (add this to your `JWT_AUDIENCES` environment variable)
+   - (JWT) Profile → Auth0
+
+2. **Enable a default audience for your tenant** (per [this community post](https://community.auth0.com/t/rfc-8707-implementation-audience-vs-resource/188990/4)) so that Auth0 issues an unencrypted RS256 JWT.
+
+   - Tenant settings > Default Audience > Add the API identifier you created in step 1.
+
+3. **Enable Dynamic Client Registration**
+
+   - Go to Dashboard > Settings > Advanced and enable the [OIDC Dynamic Application Registration](https://auth0.com/docs/get-started/applications/dynamic-client-registration?tenant=openai-mcpkit-trial%40prod-us-5&locale=en-us).
+
+4. **Add a social connection to the tenant** for example Google oauth2 to provide a social login mechanism for uers.
+   - Authentication > Social > google-oauth2 > Advanced > Promote Connection to Domain Level
+
+### 2. Set the environment variables
+
+Create `authenticated_server_python/.env` with the values below:
+
+```env
+AUTHORIZATION_SERVER_URL=https://your-domain.example.com
+RESOURCE_SERVER_URL=https://your-domain.example.com/mcp
+```
+
+- `AUTHORIZATION_SERVER_URL`: Base URL for your OAuth authorization server (Auth0 tenant). This is what ChatGPT uses to start the OAuth flow.
+- `RESOURCE_SERVER_URL`: Public URL to this MCP server's `/mcp` endpoint. This is the protected resource URL advertised in the OAuth metadata.
+
+### 3. Customize the app
+
+Adjust the `WWW-Authenticate` construction or scopes to match your security model.
+
+## Run the app
+
+### Serve the static assets
+
+In a separate terminal, from the root of the directory, build and serve the widget assets (required for the UI):
+
+```bash
+pnpm run build
+pnpm run serve
+```
+
+### Install python requirements
+
+```bash
+cd authenticated_server_python/
+python -m venv .venv
+source .venv/bin/activate
+pip install -r requirements.txt
+```
+
+### Run the MCP server
+
+Run the following command to start the MCP server:
+
+```bash
+uvicorn authenticated_server_python.main:app --port 8000
+```
+
+### Tunnel with ngrok
+
+In a separate tab, to expose the server publicly (required for ChatGPT to reach it), tunnel the local port with ngrok:
+
+```bash
+ngrok http 8000
+```
+
+Copy the `https://...ngrok-free.app` URL and set `RESOURCE_SERVER_URL` in `.env` to `https://...ngrok-free.app/mcp`
+
+The server listens on `http://127.0.0.1:8000` and exposes the standard MCP endpoint at `GET /mcp`.
+
+The `search_pizza_sf` tool echoes the optional `searchTerm` argument as a topping and returns structured content plus widget markup. Unauthenticated calls return the MCP auth hint so the Apps SDK can start the OAuth flow.
+
+The `see_past_orders` tool requires OAuth and returns the `mixed-auth-past-orders` widget with past orders data.
