What does MCP mean?
Model Context Protocol: the AI builder acronym for giving assistants a standard way to reach tools, files, databases, and workflows without custom glue for every app.
MCP is a shared connector pattern for AI apps. Instead of every assistant needing a custom integration for every tool, MCP gives builders a common client-server protocol.
Origin and usage
Introduced by Anthropic in November 2024 as an open standard for connecting AI assistants to external systems, then adopted across developer tools and agent platforms.
Source type: product-term. Last checked: 2026-07-01.
Official protocol term with strong builder-community usage; the slang value is in how developers use MCP as shorthand for tool-connected AI workflows.
Examples
- The demo worked after we replaced three brittle plugins with one MCP server.
- MCP is useful, but do not treat a random server as harmless just because the acronym sounds official.
