Claude Code installs Search from the `levirge/search` plugin marketplace:

```bash
claude plugin marketplace add levirge/search
```

```bash
claude plugin install search@levirge-search
```

This installs the `/search:*` commands and connects the MCP server. Sign in
with OAuth on first use; workspace bearer tokens remain as a fallback.

Restart Claude Code after installing, then verify with a read-only call —
ask it to run `stealth_list`, which returns the stealth-domain registry.
