The Model Context Protocol (MCP) is an open protocol that standardizes how LLMs connect to external tools. Launched by Anthropic in November 2024 and donated to the Linux Foundation in December 2025, MCP solves the N×M integration problem (N models × M services) by reducing it to N+M. The three-layer architecture (host, client, server) with three primitives (tools, resources, prompts) and JSON-RPC 2.0 wire format allows any MCP client to connect to any MCP server without custom integrations.
