Model Context Protocol (MCP)

The Model Context Protocol (MCP) is an open standard, introduced by Anthropic in 2024, that lets AI applications connect to external tools and data sources through a uniform interface.

MCP defines how a client (an AI app) and a server (a tool or data source) exchange capabilities, so any compliant model can use any compliant tool without custom integration.

It is widely adopted as the connective layer for agentic systems, reducing the bespoke glue code each integration used to require.
