Dynamic Client Registration (DCR) is a protocol designed to automate the registration process of client applications with authorization servers, eliminating the need for manual pre-registration. This protocol, defined in RFC 7591, operates within the OAuth and OpenID Connect (OIDC) ecosystems and simplifies integration by allowing applications to dynamically discover authorization servers, submit metadata, and receive client credentials programmatically. DCR addresses various challenges in digital identity management, such as reducing integration friction, enhancing security for mobile applications, and supporting the scalability of multi-tenant SaaS platforms. It is particularly valuable in AI and agentic systems, where autonomous operation requires secure machine-to-machine communication without human intervention. By automating these processes, DCR facilitates more efficient, secure, and scalable connections in modern digital environments, ultimately supporting the broader trend towards automation and interoperability in the tech ecosystem.
