Context7 Cli

This is a CLI wrapper that pulls fresh library docs when your training data might be stale, manages AI coding skills (install, search, generate custom ones), and sets up the Context7 MCP server for your editor. You'd reach for it when you need current API signatures for a library, want to grab pre-built skills from repos like /anthropics/skills, or need to configure Context7 for Claude Code or Cursor. The two-step docs flow (resolve library ID, then fetch) feels a bit clunky, but it's honest about what it does. Most commands work without auth, though generating custom skills requires login. If you're already in the Context7 ecosystem, this ties the pieces together.

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:

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 Use when writing code, verifying API signatures, or when training data may be outdated.
Setup — Configure Context7 MCP for Claude Code / Cursor / OpenCode.

Quick Reference

# 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 status
