MCP stands for
Model Context Protocol. It’s an open standard that lets AI applications connect to external tools, data, and software through a common interface.
Think of it as a universal connector for AI: instead of building a separate custom integration for every AI assistant and business system, developers can expose a system’s capabilities through MCP so compatible AI applications can discover and use them.
How it works
- The AI application is where you make a request.
- An MCP client within that application connects to an MCP server.
- The server exposes capabilities—such as searching documents, looking up a customer, or executing an action—and describes how to use them.
For example, a CRM’s MCP server could let an assistant look up customer information or prepare an update using natural-language requests. What the assistant can actually do depends on which capabilities the server exposes.
How it differs from an API
An API provides access to a particular service. MCP provides a standardized way for AI applications to discover and use capabilities, often by calling that service’s existing API behind the scenes. It doesn’t replace the API; it adds a consistent, AI-facing interface.
MCP is the connection standard—not the AI model or the agent deciding what to do.
