`InMemoryTransport` has been removed from the public API surface. It was previously used for in-process client-server connections and testing.

```typescript
// v1
import { InMemoryTransport } from '@modelcontextprotocol/sdk/inMemory.js';
// v2 (testing only — @modelcontextprotocol/core is internal, not for production use)
import { InMemoryTransport } from '@modelcontextprotocol/core';
// v2
import { InMemoryTransport } from '@modelcontextprotocol/server';
