description: Use the ctx7 CLI to fetch library documentation, manage AI coding skills, and configure Context7 MCP. Activate when the user mentions "ctx7" or "context7", needs current docs for any library, wants to install/search/generate skills, or needs to set up Context7 for their AI coding agent.

# 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:
|
|
|
|
```bash
|
|
npm install -g ctx7@latest
|
|
```
|
|
|
|
## 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 Use when writing code, verifying API signatures, or when training data may be outdated.
|
|
- **[Skills management](references/skills.md)** — Install, search, suggest, list, remove, and generate AI coding skills.
|
|
- **[Setup](references/setup.md)** — Configure Context7 MCP for Claude Code / Cursor / OpenCode.
|
|
|
|
## Quick Reference
|
|
|
|
```bash
|
|
# 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
|
|
|
|
```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. 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:
|
|
|
|
```bash
|
|
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
