 ## Sampling
 
+> **Deprecated (SEP-2577):** Sampling is deprecated and will be removed in a future release. It remains fully functional for now. See [SEP-2577](https://github.com/modelcontextprotocol/modelcontextprotocol/pull/2577).
+
 Sampling flips the usual direction: the server asks the client to run an LLM completion. The server sends a `create_message` request, the client processes it through its LLM, and returns the result.

 Roots tell servers which directories or projects the client is working in. A root is a URI (typically `file://`) pointing to a workspace or repository. Servers can query roots to know where to look for files and how to scope their work.

 ## Logging

+
 Servers can send structured log messages to clients. The client sets a minimum severity level, and the server sends messages through the peer notification interface.
