context7

Context7 pulls up-to-date, version-specific documentation and code examples straight from the source — and places them directly into your prompt.

Context7 fetches up-to-date code examples and documentation right into your LLM's context. No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.

Works in two modes:

• CLI + Skills — installs a skill that guides your agent to fetch docs using ctx7 CLI commands (no MCP required)
• MCP — registers a Context7 MCP server so your agent can call documentation tools natively
