Install from the plugin marketplace:

```bash
codex plugin marketplace add https://github.com/levirge/search
```

Or add the MCP server directly to `~/.codex/config.toml`:

```toml
[mcp_servers.search]
url = "https://search.levirge.com/mcp"
# Token fallback — env var holding your bearer token:
bearer_token_env_var = "SEARCH_TOKEN"
```

OAuth is negotiated on connect; the `SEARCH_TOKEN` env var is only needed for
the bearer-token fallback. Restart Codex after installing, then verify with a
read-only call — `stealth_list` returns the stealth-domain registry.
