Conversation
## Motivation and Context The client documentation equated `MCP::Client#connect` with the MCP initialization handshake, which MCP 2026-07-28 removed: a modern connection probes `server/discover` instead. Calling `connect` first is still required on either era, since it settles the lifecycle and registers the identity, capabilities, and protocol version that modern requests carry in `_meta`, so the wording now names that rather than the handshake. ## How Has This Been Tested? Without `connect` a modern server rejects the first request; with it the same call succeeds. The documentation site builds with the new wording. ## Breaking Changes None. The change is documentation prose and example comments.
