Namespace Nexus\Mcp\Server

Mints and checks the requestState an InputRequiredResult carries across a round trip. The payload travels in the clear and is signed, not encrypted, so a state may hold a continuation marker but never a secret.

Thin shell that drives a single transport's lifecycle, exposing a blocking run() and a non-blocking listen().

Fluent builder that wires the per-feature stores, the dispatch kernel, and the lifecycle shell into a runnable Server instance.

Context passed to server-side request handlers.

A store whose listing can change after build(), and which reports each change to its listeners. The store names no notification type. Which notifications/*\/list_changed a change becomes is fixed by the feature the listener registered on.

How much of the server's identity rides the _meta of the results it sends, outside the server/discover result that always carries the whole block.
