MCP Inspector moves to ext-apps 2.0.0 and deletes four separate SDK-v1 compatibility shims, including a whole notification-handler Proxy
ext-apps 2.0.0 (published 2026-09-08) peers on the SDK v2 split packages — @modelcontextprotocol/client and core at ^2.0.0, server optional, zod ^4.2.0. PR #2358 (merged 2026-09-14) bumps it in two commits so the bump bisects alone, then removes the UiMetaShape structural stand-in, two ConstructorParameters casts, and the Proxy in inspectorClient.ts that translated v1 schema-first setNotificationHandler(Schema, handler) into the method-string form. The PR documents that ext-apps#733 is not in 2.0.0, so the elicitation mirrors stay, and pins the drift with a test because EXTENSION_ID is still exported only from /server and would drag the optional server peer into the browser bundle.
