MCP stands for Model Context Protocol, an open standard launched by Anthropic in 2024 for connecting AI models to data sources and tools. Tech jargon. Not concerning. If your kid uses it constantly, ask them where they first heard it, not to police their speech but to understand which online community they are in. Most slang of this kind moves through TikTok and group chats, so seeing it in your child's vocabulary just means they are plugged into normal teen internet culture.

The real value isn't just running scripts; it's interoperability.<br>MCP allows any client (Claude, Cursor, IDEs) to dynamically discover and interact with any resource (Postgres, Slack) without custom glue code.

Model Context Protocol — Anthropic's open standard for connecting LLMs to tools and data sources. Standardizes how an LLM can talk to databases, APIs, and local services.
"Wired up a Postgres MCP server and now Claude can query our DB directly."
Origin: Anthropic's open standard, announced November 2024. Modeled loosely on the Language Server Protocol — an attempt to standardize how LLMs connect to databases, APIs, and local tools without each vendor reinventing the wiring.

For ESL learners
MCP is an AI-industry initialism for "Model Context Protocol," an open standard introduced by Anthropic in late 2024 for connecting AI models to external data sources and tools. Use in AI-engineering writing. Formal equivalent: "Model Context Protocol" (spelled out on first use). Common non-native mistake: confusing with other MCP acronyms (Microsoft Certified Professional, Master Control Program). Read or listen to the word in context several times before trying it yourself; the right register is harder to learn than the dictionary meaning.

Model Context Protocol — Anthropic's open spec for letting LLMs talk to external tools and data sources via a uniform interface. The plumbing layer for agentic AI in 2025-2026.
Just hook it up over MCP — every modern client speaks it.

For specific readers
Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
