The Model Context Protocol (MCP) is an open standard that enables AI applications to connect securely and standardize their interactions with external systems, tools, and data sources. Think of it like a universal adapter, or a "USB-C port for AI applications".
Thanks to the MCP standard, AI agents and other LLMs can do things like send an email (external systems), generate a new map layer (tools), or query data in a database (data sources), enabling them to interact with the real world, with enterprise-grade setups. This is particularly useful in enterprise settings where AI needs to retrieve information from internal documents, databases, and other proprietary systems.
