4043 Auth extension support (OAuth Client Credentials and Enterprise-Managed Authorization) is tracked separately from the core MCP authorization features (DCR, CIMD). Check each extension's specification and the [ext-auth repository](https://github.com/modelcontextprotocol/ext-auth) for the latest implementation status.
