upstash/context7 ? reverse-engineered prompt

I want to build a platform that helps coding AIs stay up-to-date with library and framework documentation. When I'm prompting an AI like Cursor or Claude, it often uses old code examples from its training data, which leads to bugs and hallucinated APIs.

This tool, let's call it Context7, should solve that. When a user includes a keyword like "use context7" in their prompt, it should automatically find the latest, version-specific documentation for the library they're asking about and feed it directly into the AI's context. This will ensure the AI generates accurate, modern code.

It should be built as a TypeScript project and function as an MCP server that AI code editors can connect to. It should also have a simple command-line tool, maybe ctx7, that lets users install it and get an API key. The platform needs to be extensible for different AI clients and have a system for handling different "skills" or "rules."
