Setup

ctx7 setup

One-time command to configure Context7 for your AI coding agent. Prompts for mode on first run:

• MCP server — registers the Context7 MCP server so the agent can call tools natively
• CLI + Skills — installs a find-docs skill that guides the agent to use ctx7 CLI commands (no MCP required)

ctx7 setup                     # Interactive — prompts for mode, then agent/install target
ctx7 setup --mcp               # Skip prompt, use MCP server mode
ctx7 setup --cli               # Skip prompt, use CLI + Skills mode

# MCP mode — target a specific agent
ctx7 setup --claude            # Claude Code only
ctx7 setup --cursor            # Cursor only
ctx7 setup --opencode          # OpenCode only

# CLI + Skills mode — target a specific install location
ctx7 setup --cli --claude      # Claude Code (~/.claude/skills)
ctx7 setup --cli --cursor      # Cursor (~/.cursor/skills)
ctx7 setup --cli --universal   # Universal (~/.agents/skills)
ctx7 setup --cli --antigravity # Antigravity (~/.config/agent/skills)

ctx7 setup --project           # Configure current project instead of globally
ctx7 setup --yes               # Skip confirmation prompts

Authentication options:

ctx7 setup --api-key YOUR_KEY  # Use an existing API key (both MCP and CLI + Skills mode)
ctx7 setup --oauth             # OAuth endpoint — MCP mode only (IDE handles the auth flow)

Without --api-key or --oauth, setup opens a browser for OAuth login. The device flow returns an API key that setup uses for authentication. --oauth is MCP-only.

What gets written — MCP mode:

• MCP server entry in the agent's config file (.mcp.json for Claude, .cursor/mcp.json for Cursor, .opencode.json for OpenCode)
• A Context7 rule file instructing the agent to use Context7 for library docs
• A context7-mcp skill in the agent's skills directory

What gets written — CLI + Skills mode:

• A find-docs skill in the chosen agent's skills directory, guiding the agent to use ctx7 library and ctx7 docs commands
