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

### Installing via NPM

#### Configure environment:

- You can set configuration options using command-line arguments or environment variables:
  - `--keycloak-url <Keycloak Instance URL>`
  - `--keycloak-admin <Admin Username>`
  - `--keycloak-admin-password <Admin Password>`
- These arguments override environment variables if both are set.

#### Start the server:

The server is available as an NPM package:

```bash
# 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

### Using NPM Package

Configure the server in your Cursor IDE, Cline or Claude Desktop MCP configuration file:

```json
{
  "mcpServers": {
    "keycloak": {
      "command": "npx",
      "args": ["-y", "keycloak-mcp"],
      "env": {
