```bash
$ npx -y @smithery/cli install @HaithamOumerzoug/keycloak-mcp --client claude

- These arguments override environment variables if both are set.

# Direct usage with npx
$ npx -y keycloak-mcp --keycloak-url <Keycloak Instance URL> --keycloak-admin <Admin Username> --keycloak-admin-password <Admin Password>

# Or global installation
$ npm install -g keycloak-mcp@latest
$ keycloak-mcp --keycloak-url <Keycloak Instance URL> --keycloak-admin <Admin Username> --keycloak-admin-password <Admin Password>
```

## Configuration
