Inject live signals into Cursor

Stop guessing what your production environment looks like. Use `search_signals` to bring real-time alert data into your editor context. You can see exactly what processes triggered an alert while you write the patch. It makes debugging security regressions much faster.

Automate rule creation in Cursor

Define your security logic as code and push it to your SIEM. Use `create_rule` to set up new detection logic based on the application patterns you're currently building. It keeps your detection logic in sync with your deployment. You won't have to jump to the dashboard to define new risk scores.

Audit coverage with Cursor

Check if your new code changes are covered by existing detection rules. Use `list_detection_rules` to verify your project's security footprint. You can quickly identify missing logic before you push to production. It turns security auditing into a standard part of your coding workflow.

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Elastic Security MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
