Module handler 

Answering the requests a server sends the client.

Through 2025-11-25 a server can ask the client to run a model (sampling/createMessage), ask its user a question (elicitation/create) or list its roots (roots/list), and it does so as a JSON-RPC request on the response stream of whatever call needed the answer. The call is blocked until the client replies, so a client that declared one of these capabilities and then did not answer left the server’s tool waiting forever.

ServerRequestHandler is that answer. It is a port the caller implements: this crate cannot know what a person would say, and answering on their behalf would be inventing consent.

2026-07-28 removed server-to-client requests. The same three questions now arrive as an InputRequiredResult and are answered through call_resolving.
