# 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)
```bash
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:**
```bash
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. MCP mode additionally generates a new API key after login. `--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
