- Replace build_server_card() with the ServerCard.from_server() classmethod, matching the SDK's from_* alternate-constructor idiom; the _ServerIdentity protocol moves to mcp.shared.experimental.server_card alongside it. - Make DiscoveryResult iterable over its listings (__iter__/__len__), so 'for listing in result:' works without the .listings attribute hop. - Remove the client-side server_card_url() helper: card URLs must come from an AI Catalog entry per the discovery spec, never be constructed by the client. fetch_server_card's docstring now says so. - Explain the RFC 6598 shared address space constant in the SSRF guard and rename it _CGNAT_NETWORK -> _SHARED_ADDRESS_SPACE; ipaddress reports these addresses as neither private nor global, so the guard names them explicitly. All symbols are experimental (no deprecation cycle), so the removals are clean.
