Cohere's Model Context Protocol (MCP) is an open standard that allows AI applications to access data and perform defined actions across external systems such as databases, document repositories, and workflow platforms. MCP operates as a protocol within the application and integration layer of the AI stack, reducing the need for separate integrations between AI applications and business systems. This makes MCP particularly relevant as organizations transition from isolated AI pilots to applications that require interaction with live enterprise systems. By providing a common way to structure these integrations, MCP can make AI applications easier to extend, maintain, and adapt as enterprise needs evolve. The protocol uses a client-server architecture, where the AI application acts as the host, and MCP clients connect to MCP servers to access contextual information, tools, and prompts. MCP servers expose resources, tools, and prompts that AI applications can use to perform tasks requiring external context or action. *Source: [cohere](https://cohere.com/blog/guide-to-mcp)*
