Protocols like MCP and A2A have simplified API integration by enabling flexible access and usage of application interfaces. However, delivering large datasets in a customized, filtered, and secure way for different clients has been a challenge. This is where Dynamic Contract Protocol (DCP) comes in. DCP dynamically generates APIs at runtime based on a contract defined by the client, improving efficiency and shortening integration time. DCPs philosophy of contract-first, declarative, dynamic, and policy-bound design represents a new mindset in API development. It enables a true intent handshake between client and server, simplifying the process of data retrieval and enhancing security measures.
