Context7

Pull current, version-accurate library documentation straight into the model's context.

[documentation][developer-tools]

Context7 solves a narrow but common problem: a model's training data goes stale, so it suggests deprecated APIs or hallucinates methods that never existed. This server fetches up-to-date documentation and code examples for the library and version you're actually using, and drops them directly into the conversation.

Works with a large and growing index of popular open-source libraries across languages.
