+The ToolHive operator deploys a proxy in front of Notion's hosted remote MCP
+server using an `MCPRemoteProxy` resource with an
+[embedded authorization server](../concepts/embedded-auth-server.mdx).
 
-The ToolHive Kubernetes Operator does not currently support remote MCP servers
-using dynamic OAuth authentication. Instead, you can run the
-[local Notion MCP server](https://github.com/makenotion/notion-mcp-server) in
-Kubernetes using a static integration key.
+The examples below use `https://notion-mcp.example.com` as a placeholder for
+wherever you'll expose the proxy outside the cluster. Set up an Ingress or
+Gateway route pointing at the proxy Service first (see
+[Connect clients to MCP servers](../guides-k8s/connect-clients.mdx#connect-from-outside-the-cluster))
+and substitute your real hostname everywhere this placeholder appears. Notion
+redirects the user's browser to this URL during authentication, so it must be
+genuinely reachable over HTTPS, not just resolvable inside the cluster.

-Create an integration in Notion to obtain an authentication token by following
-the instructions in the MCP server's
-[README](https://github.com/makenotion/notion-mcp-server?tab=readme-ov-file#installation).
+Notion's remote MCP server (`mcp.notion.com`) uses Dynamic Client Registration
+(RFC 7591) for third-party OAuth clients. The embedded authorization server's
+`dcrConfig` field handles this automatically: it registers a client with Notion
+at startup using Notion's discovery document and caches the returned
+credentials, so there's no manual registration step and no client secret to
+store.
 
-Create a Kubernetes secret containing your Notion integration token
-("`ntn_****`"):
+Generate a signing key and an HMAC key for the embedded authorization server,
+and store them as Secrets:
 
 ```bash
-kubectl -n toolhive-system create secret generic notion-token --from-literal=token=<YOUR_TOKEN>
+openssl genpkey -algorithm RSA -pkeyopt rsa_keygen_bits:2048 -out signing-key.pem
+openssl rand -base64 32 > hmac-key.txt

+kubectl create secret generic notion-auth-hmac-key -n toolhive-system \

+Set `issuer` on both the `MCPExternalAuthConfig` and `MCPOIDCConfig` to a bare

+(`/oauth/register`, `/oauth/authorize`, `/oauth/token`, `/oauth/callback`) are
+always served at the host root, so a path in `issuer` breaks discovery and every
+authentication attempt fails with a generic "authorization header required"
+error.
+
+For the same reason, set `redirectUri` on the upstream provider explicitly to
+`<issuer>/oauth/callback`, as shown above. Because `resourceUrl` includes the
+`/mcp` path, the
+[default computed from it](../guides-k8s/embedded-auth-server-k8s.mdx#default-callback-url-for-upstream-providers)
+would land on a path nothing serves.
+
+:::

 Apply the manifest to your Kubernetes cluster:
 
 ```bash
-kubectl apply -f notion.yaml
+kubectl apply -f notion-proxy.yaml
+```
+
+Check the proxy status:
+
+```bash
+kubectl get mcpremoteproxy notion -n toolhive-system
 ```
 
+Connect your MCP client to the proxy's URL. Each client authenticates once
+through the OAuth flow, redirecting through Notion, then reuses the token issued
+by the embedded authorization server. For production deployments, configure
+Redis-backed session storage so tokens survive pod restarts. This matters more
+than usual here: the DCR-issued client credentials live in the same store as
+sessions, so without Redis-backed storage, a pod restart also registers a
+brand-new OAuth client with Notion instead of reusing the previous one, leaving
+the old registration orphaned. See
+[Horizontal scaling](../guides-k8s/run-mcp-k8s.mdx#horizontal-scaling) and
+[Redis session storage](../guides-k8s/redis-session-storage.mdx).

 If OAuth authentication fails or times out:
 
+**CLI or UI:**
+
 1. Ensure the callback port is not blocked by a firewall
 2. Check that your browser allows pop-ups from ToolHive
 3. Try restarting the server with `thv restart notion-remote`
 
+**Kubernetes:** Your client authenticates against the embedded authorization
+server, which then completes a separate OAuth exchange with Notion using
+credentials obtained automatically via Dynamic Client Registration. Check the

+```bash
+kubectl logs -n toolhive-system -l app.kubernetes.io/instance=notion | grep -i oauth
