Fix web vulnerabilities directly inside Cursor

Let your Cursor agent pull Beagle Security failures directly into your active coding window. By calling `get_test_result` via your MCP Server, Cursor reads the exact issues from your latest run so you can write patches on the spot. Instead of guessing what went wrong, you get the raw JSON payload in Cursor. Your agent analyzes the failing endpoints and edits your local files to close the gaps immediately.

Control active test suites from your editor

Launching a new Beagle Security scan does not require switching from Cursor to a browser. This MCP Server allows Cursor to run `start_test` directly from your editor sidebar when you push new code. Keep an eye on the progress inside Cursor with `get_running_tests`. If something looks off, your agent invokes `stop_test` to kill the run before it wastes your testing quota.

Map your security scope without leaving Cursor

Managing multiple microservices in Cursor requires knowing exactly which application you are targeting. Cursor calls `list_applications` to match your local repository to the correct Beagle Security target. It retrieves metadata via `get_application` and `list_projects` to ensure your Cursor agent runs tests against the staging environment, not production. You avoid accidental scans on live systems this way.

Setup guide

Set up Beagle Security MCP in Cursor

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 Beagle 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.
4

Verify the connection

Ask Cursor something like "List my recent Beagle Security transactions." If the MCP tools are loaded correctly, Cursor will call the Beagle Security tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "beagle-security-alternative-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
