## ctx7 CLI

The Context7 CLI does three things: fetches up-to-date library documentation, manages AI coding skills, and sets up Context7 MCP for your editor.

Make sure the CLI is up to date before running commands:

```
`npm install -g ctx7@latest
`
```

Or run directly without installing:

```
`npx ctx7@latest <command>
`
```

## What this skill covers

* Documentation — Fetch current docs for any library. Use when writing code, verifying API signatures, or when training data may be outdated.

* Skills management — Install, search, suggest, list, remove, and generate AI coding skills.

* Setup — Configure Context7 MCP for Claude Code / Cursor / OpenCode.

## Quick Reference

```
`# Documentation
ctx7 library <name> <query> # Step 1: resolve library ID
ctx7 docs <libraryId> <query> # Step 2: fetch docs

# Skills
ctx7 skills install /owner/repo # Install from a repo (interactive)
ctx7 skills install /owner/repo name # Install a specific skill
ctx7 skills search <keywords> # Search the registry
ctx7 skills suggest # Auto-suggest based on project deps
ctx7 skills list # List installed skills
ctx7 skills remove <name> # Uninstall a skill
ctx7 skills generate # Generate a custom skill with AI (requires login)

# Setup
ctx7 setup # Configure Context7 MCP (interactive)
ctx7 login # Log in for higher rate limits + skill generation
ctx7 whoami # Check current login status
`
```

## Authentication

```
`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. Exceptions: `skills generate` always requires it; `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:

```
`export CONTEXT7_API_KEY=your_key
`
```

## Common Mistakes

* Library IDs require a `/` prefix — `/facebook/react` not `facebook/react`

* Always run `ctx7 library` first — `ctx7 docs react "hooks"` will fail without a valid ID

* Repository format for skills is `/owner/repo` — e.g., `ctx7 skills install /anthropics/skills`

* `skills generate` requires login — run `ctx7 login` first
