Model Context Protocol (MCP) is a standardized approach to organize information for large language models like ChatGPT or Claude, ensuring they have relevant and structured context for generating answers. In 2025, MCP is trending due to the increasing complexity of AI systems and the need for modular and scalable context management solutions. MCP breaks context into modular pieces called components, which are then composed and managed by an MCP-style context builder, enabling predictable and programmable prompting for generative AI projects. While MCP offers benefits like modular context management and scalability, it can be more complex to implement and may not be necessary for simple prompts.
