Version 2.0.2 introduces resource-specific bearer token validation and enforces single-use server/transports per connection or request. This release affects authentication flows and backend code structure for all users upgrading from 2.0.1.
The @modelcontextprotocol/hono library now enforces a one-connection-per-server-object policy, breaking patterns where a single server or stateless transport is reused for multiple HTTP requests.
The 2.3.0 release of @modelcontextprotocol/client, server, and related packages mandates one server per request, changes HTTP redirect handling, and adds security and validation options. Developers must update their architecture and configuration to stay compatible and secure.
