What it does
AI models learn from data that can be a year or more old, so they sometimes suggest outdated code or invent functions that don't exist. Context7 fixes this by fetching up-to-date, version-specific documentation and code examples and handing them to your coding assistant.
You add "use context7" to a request, or set a rule so it happens automatically, and the assistant looks up the right library before answering. You can also name an exact library or version.
It can be set up as a skill that uses a small command-line tool, or as an MCP server, a standard way to give AI assistants new tools. A free account key gives higher usage limits.
Who it's for
Programmers who use AI coding assistants such as Cursor or Claude Code.
