Lors de la version2026-07-28, le client choisit de consigner les messages pour chaque demande io.modelcontextprotocol/logLevel en activant cette option _meta (l'logging/setLevelopération est supprimée dans cette version). Le serveur envoie notifications/message uniquement au niveau demandé ou au-delà. Incluez également les en-têtes Mcp-Method Mcp-Name et les métadonnées de demande et les champs de _meta version. L'MCP-Protocol-Versionen-tête doit correspondre_meta.io.modelcontextprotocol/protocolVersion. Votre passerelle supportedVersions doit inclure2026-07-28.
