ctx7 CLI
The Context7 CLI does two things: fetches up-to-date library documentation and sets up Context7 MCP for your editor.
Make sure the CLI is up to date before running commands:
bash
npm install -g ctx7@latestOr run directly without installing:
bash
npx ctx7@latest <command>What this skill covers
- [Documentation](references/docs.md) — Fetch current docs for any library. Use when writing code, verifying API signatures, or when training data may be outdated.
- [Setup](references/setup.md) — Configure Context7 MCP for Claude Code / Cursor / OpenCode.
Quick Reference
bash
# Documentation
ctx7 search <query> # Search all libraries in one step
ctx7 library <name> <query> # Step 1: resolve library ID
ctx7 docs <libraryId> <query> # Step 2: fetch docs
# Setup
ctx7 setup # Configure Context7 MCP (interactive)
ctx7 login # Log in for higher rate limits
ctx7 whoami # Check current login statusAuthentication
bash
ctx7 login # Opens browser for OAuth
ctx7 login --no-browser # Prints URL instead of opening browser
ctx7 logout # Clear stored tokens
ctx7 whoami # Show current login status (name + email)Most commands work without login. Exception: ctx7 setup requires it unless --api-key or --oauth is passed. Login also unlocks higher rate limits on docs commands.
Set an API key via environment variable to skip interactive login entirely:
bash
export CONTEXT7_API_KEY=your_keyCommon Mistakes
- Library IDs require a
/prefix —/facebook/reactnotfacebook/react - Always run
ctx7 libraryfirst —ctx7 docs react "hooks"will fail without a valid ID
