MCP protocol version history
Newest protocol versions first, then most recently seen. Repeated client releases and version outcomes are counted together. Protocol acceptance and request outcomes are shown separately; an unsupported method does not reject an accepted version. A counter-offer or discovery response does not prove the client used that version. New observations from token-linked sessions are associated with the exact OAuth identity; older observations without an identity link remain on the global protocol history.
