# Scanning in IDEs

After you've completed the [configuration of the Lineaje MCP server](/unifai/setting-up/configuring-the-lineaje-mcp-server.md), UnifAI automatically scans for policy violations.

{% hint style="info" %}
Policies are disabled by default. You must [enable policies in UnifAI](/unifai/policies/viewing-and-enabling-policies.md#enable-or-disable-policies) to allow policies scanning. 
{% endhint %}

<summary>On-demand scanning</summary>

Use this workflow when hook functionality is disabled in your environment or unavailable in your IDE.

You can request manuals scans for policy violations:

1. To check for violations, open, edit, and save the file you want to be scanned. You can do this in an IDE (for example, Cursor) or CLI (for example Claude Code).
2. Run the command  `scan file_processor.py using Lineaje`. Replace `file_processor.py` with your file name. Lineaje performs a policy‑violation scan on the specified file and generates a detailed report. The report includes the project evaluated, the policies applied, and the controls enforced during the scan.

{% hint style="info" %}
If the Lineaje MCP server is not detected during scanning, disable the MCP server, then enable it. In addition, select the latest agent model instead of an auto Agent.
{% endhint %}

The following examples display Lineaje suggestions for modifying code to prevent policy violations.

<summary>Installing a hook for automatic scanning</summary>

Use this workflow when hook integration is available in your IDE.

Hooks automatically detect changes to a file and send the file to the MCP server for policy violation detection and remediation.

### Cursor

To install a hook in Cursor:

1. Open a file in your repository.
2. Go to **Settings** > **Hooks.**
3. Click **Open user config**.
4. Copy and paste the following JSON configuration snippet:

```
{
  "version": 1,
  "hooks": {
    "afterFileEdit": [
      {
        "command": "python3 /path/to/unifAI-hooks/hooks/after_file_edit_hook_handler.py"
      }
    ],
    "stop": [
      {
        "command": "python3 /path/to/unifAI-hooks/hooks/stop_hook_handler.py"
      }
    ]
  }
}
```

4. Open the file that you want Lineaje to scan.
5. As you write code, Lineaje evaluates the selected file for policy violations and produces a detailed report. The report lists the project reviewed, the applied policies, and the controls enforced.
