What is Model Context Protocol (MCP)?

MCP is an open standard that lets AI assistants connect to external tools, data, and services through one consistent interface, so any MCP client can use any MCP server.

The Model Context Protocol (MCP) defines a common contract between AI clients (Claude, IDE agents, custom apps) and servers that expose capabilities — a database, a file system, an API, a browser. Instead of bespoke glue per integration, you publish an MCP server once and the whole ecosystem can use it.

MCP exploded across 2025-26 because it turns 'wire this one model to this one tool' into a reusable building block. The winning servers are the ones that stay compatible as the young spec evolves and solve an integration developers were previously hand-rolling.
