v2.0.1
Follow-up hardening from a review of the 2.0.0 transport. No API changes.
- Attach
_authonly on the request dispatch path, so a client-posted JSON-RPC response (answering a serversampling/elicitationrequest) no longer carries it into the delivered map. Server-internal; matches 1.x. barrel_mcp_http_listenerbacks off briefly on non-closedaccept errors, so file-descriptor exhaustion (emfile) throttles the acceptor instead of spinning the CPU.
See CHANGELOG.md for full notes.
