Inside the MCP Protocol: Revolutionizing data communication and system interoperability

Patil, Piyush (2025) Inside the MCP Protocol: Revolutionizing data communication and system interoperability. World Journal of Advanced Research and Reviews, 26 (1). pp. 3055-3071. ISSN 2581-9615

The Model Context Protocol (MCP) is a revolutionary step in transmitting data and system interoperability to complete the space in the areas of digital and unrelated ones. Because digital ecosystems are becoming increasingly complex, there is a low latency, high throughput, and universally compatible communication framework. The paper discusses its evolution, architecture, and key features of the high availability middleware MCP. Secondly, we discuss how MCP enhances the interoperability of legacy systems, modern platforms, IoT, and cloud IaaS. Next, the article shows how MCP can outperform traditional protocols, such as TCP/IP, MQTT, and REST APIs, via comparisons. The main use cases where the protocol is used are in the real world – for manufacturing, smart cities, defense, IoT integration, and the like- and are based on extensive scalability. However, we also look at the developer experience, available SDKs, tooling, community support, and tech challenges overall for an app developer. Finally, the future scope of MCP in terms of those emerging technologies is analyzed in the domain of AI, blockchain, and quantum computing. Unlike other emerging systems, MCP is a forward-thinking communication standard intended to be a solution not only to a messy world as it stands today with fragmentation amongst different systems but also to what the world will exist as it moves towards the future.
