 # Host a plugin with Sites MCP
 
 Sites MCP is the default hosting path for a new cloud plugin. Read the
-available Sites plugin's `sites-mcp` skill and follow its setup,
-authentication, publishing, and connection workflow. Use `sites-building` and
-`sites-hosting` as directed there. If the skill or backend is unavailable,
+available Sites plugin's `sites` skill, then its **Site MCP server** reference
+at `references/site-mcp-server.md`, relative to that skill's directory. Follow
+`sites` for setup and publishing, and the MCP reference for server implementation,
+authentication, and connection. If the skill, reference, or backend is unavailable,
 explain the gap and continue independent source work without promising a
 working connection or substituting another host.
 
 ## Build the requested surface
 
-Reuse an existing Site's source and project identity. Let `sites-mcp` own the
-server implementation; choose the user-facing surface from the request:
+Reuse an existing Site's source and project identity. Follow the Sites skill's
+**Site MCP server** reference for the server implementation; choose the
+user-facing surface from the request:
 
 - **Tools used in chat:** build the MCP endpoint and required storage. Keep the
   website page minimal: the app's purpose and useful connection/status information.
 - **Interactive views:** add an MCP App when a view helps the workflow. Choose
   useful [Extensions](extensions.md) and follow that guide's implementation and
   verification steps. A published website URL is not an MCP App view.
-- **A website people will use:** follow `sites-building` and `sites-hosting`.
-  Add MCP to the same application when the request also needs tools in chat;
-  a standalone website does not require a plugin or MCP server.

 ## Publish and connect
 
 Sites publishing provisions the App and its canonical private plugin. Follow

+the **Site MCP server** reference's publishing and connection steps, then verify
+the requested tools and any in-chat view. Do not use `create_plugin` to create a duplicate,
 including while provisioning is pending. Reuse the existing App/plugin on updates
 and preserve Site sharing and plugin access separately. Honor source-only requests without deploying.
 
-The account archive editor rejects canonical App plugins. To add skills to a
-Site-generated plugin, first verify an editor supports it and preserves those
-files on later Site publishes; otherwise report the limitation.
+For skills in the Site's existing plugin, follow
+[account plugin updates](../../update-plugin/references/account-updates.md#skills-in-app-backed-plugins).
+Keep website, MCP tool, and Extension changes in the existing Site source.
