Abstract

Large Language Models have become indispensable for modern AI systems, but their effectiveness in practice is limited by the complex rules for stateless integration. This phe- nomenon results in a so-called “disconnected models problem”: An AI agent controlled by an LLM is unable to keep continuity over more than one action or task. Most of the state-of-the-art systems demonstrate this flaw by utilising custom integration logic, typically called “glue code”. While such a solution can be effective in a small scale, it does not scale well and is subject to security vulnerabilities and maintenance challenges. To address these challenges, the Model Context Protocol (MCP) has been proposed as a standardised interface for con- necting AI models to external tools and data. The MCP follows a session-oriented architecture using JSON-RPC to enable more consistent and stateful interactions between systems In this survey, we examine the architecture of MCP, focusing on its host–client–server model and its main primitives, namely tools, resources, and prompts. We also present “TripSync,” a practical case study that shows how an MCP-based travel planner can coordinate multiple travel-related microservices within a single system. In addition, we compare MCP with other emerging agent communication protocols, including Agent Communication Pro- tocol (ACP), Agent-to-Agent (A2A), and Agent Network Protocol (ANP) . Based on recent studies of more than 8,000 MCP servers, we discuss the current state of the ecosystem and highlight important security concerns such as tool poisoning and credential exposure. Finally, we outline the potential role of MCP in building modular, secure, and context-aware AI systems in the future.

Full Article/Conclusion

Migrating Large Language Models to Deal with Context Using a standardised protocol-oriented architecture, rather than traditional software methods, to build and combine AI appli- cations is an important advance. “TripSync”, a trip-planning web application, is used as an example of the use of the Model Context Protocol (MCP) to build modular, flexible, AI-based applications with good context handling. MCP is a client–server framework that provides a standard interface for connecting an LLM to other tools. The multiplexing of contexts onto inputs to the LLM enables multiple applications to use the same LLM with multiple data sources. At the same time, the introduction of this protocol must be accompanied by a concern about security and ecosystem problems. Although MCP solves many of the interoperability problems, it also creates new security, governance, and long- term maintenance challenges. Research has revealed quality- of-code challenges and vulnerabilities, such as tool poisoning across multiple MCP servers. By responding to these challenges with enhanced secu- rity measures, centralised registries, and community-dictated norms, developers can shape the next wave of AI systems that are more than just powerful; they’re also safe and dependable.
