Context7

Context7 solves a common annoyance: AI coding assistants often write code for old versions of a library. It fetches current documentation and code examples for the library you are using and puts them in the model's context. You add it to your editor as an MCP server and mention it in a prompt, and it pulls in the right docs on the spot. It covers a large and growing set of libraries and frameworks. Context7 is free to use for individuals, with higher limits available for heavy use. It is a small addition that noticeably cuts down on outdated suggestions.
