Configuring Cursor

Configuring Cursor

💡
Note:
This step is only required if you are using a SASE-based deployment. If you are using the Lumia installers, no additional steps are needed to analyze Cursor.
Cursor is one of the most popular coding agents available today. However, to meet enterprise security and governance standards, specific adjustments are required.
Lumia utilizes HTTP/2, but since some enterprise proxies do not support HTTP/2 bidirectional streaming, the steps below will help you switch Cursor to HTTP/1.1. This ensures that Lumia can effectively govern the application while maintaining seamless connectivity.

Implementation Steps

We recommend first validating these settings manually on a single machine. Once verified, these JSON configurations can be deployed organization-wide via your MDM (e.g., Jamf or Intune).

1. Configure Cursor IDE

This step is required for Cloudflare and Netskope users.
(Zscaler users can skip this step, as the IDE is supported automatically).
To disable HTTP/2 in the main editor, add the following line to your settings.json file:
{
		...
		"cursor.general.disableHttp2": true
}
File Location:
  • macOS: ~/Library/Application Support/Cursor/User/
  • Windows: %APPDATA%\Cursor\User\

2. Configure Cursor CLI

This step is required for Cloudflare, Netskope, and Zscaler users.
💡
Note: Deep protocol inspection for the Cursor CLI (cursor-agent) is currently partially supported.
To configure the CLI to use HTTP/1.1, update the cli-config.json file with the following configuration:
{
		...
		"network": {
				"useHttp1ForAgent": true
		}
}
File Location:
  • macOS: ~/.cursor/
  • Windows: %USERPROFILE%\.cursor\

3. Verification

To validate the configuration:
  1. Restart Cursor.
  2. Run a test prompt or a CLI command.
  3. Confirm that the application connects and functions correctly without connectivity errors.
  4. Return to our Getting Started guide to view setup links for other applications, or proceed to Step 1.B to complete your integration.
