MCP (Model Context Protocol)

Also known as: MCP / Model Context Protocol / モデルコンテキストプロトコル

Anthropic's open protocol (Nov 2024) connecting AI agents to external tools — the LSP for AI, with a clear host/server separation.


Overview

MCP connects AI hosts (e.g. Claude Code) to MCP servers (GitHub, Slack, databases) via standardised JSON-RPC. Define tools once on the server; any compliant host can call them.

By 2026 most major coding tools support MCP. See MCP integration guide.
