What problem does it solve?
Context7 provides up-to-date, official documentation and version guidance for external libraries across languages. Use when querying library APIs, debugging dependency issues, or installing/upgrading dependencies, to ensure information comes from official docs rather than outdated knowledge.
Core Features & Use Cases
- Resolve the exact library ID for a given package/framework within a repo, factoring in per-project versions.
- Detect installed library version from common files (package.json, go.mod, pyproject.toml, etc.) to tailor guidance.
- Query official Context7 docs for precise API surfaces, configuration keys, and version-specific caveats.
- Provide doc-backed answers with version-aware notes and safe fallbacks when docs are ambiguous.
Quick Start
Ask Context7 for the latest docs by naming the library and its language, then specify an exact API surface question.
