Provides up-to-date, version-specific code documentation and examples for LLMs and AI coding assistants via CLI and MCP.
What is context7?
Context7 is a platform that provides up-to-date, version-specific code documentation and examples to LLMs and AI coding assistants. It solves the problem of AI assistants generating code based on outdated or hallucinated API information by fetching current documentation directly from source and injecting it into the prompt context.
Developers using AI coding assistants like Cursor, Claude Code, or OpenCode who need accurate, current library documentation and examples during their workflow.
Developers choose Context7 because it ensures their AI assistant has access to the same precise, version-aware information they would find in official docs, dramatically reducing errors from outdated training data and eliminating manual tab-switching.
