How to Use the Contrast Security MCP in Cursor

Q: How do I add the Contrast Security MCP Server to Cursor?

Create a .cursor/mcp.json file in your project root or add it globally in your Cursor settings. Paste the server configuration, and your Cursor agent will instantly have access to the security tools.

Q: Does the Contrast Security integration in Cursor slow down my editor?

No, it runs asynchronously. Cursor only calls tools like listapplications when you explicitly ask it to check your security posture or fix a specific bug.

Write secure code in Cursor with real-time Contrast Security vulnerability traces injected directly into your editor.

Inject live vulnerability traces into your code

Your agent queries `get_vulnerability_details` to pull the exact stack trace of a security bug into Cursor. You see the broken line of code and the security trace right next to each other. No more writing code against theoretical security bugs or digging through PDFs. This means you write patches using real telemetry instead of mock data. The agent reads the trace, analyzes your local file, and suggests the exact code change needed to resolve the issue.

Find vulnerable apps using this MCP Server

Cursor uses `list_applications` to match your local repository with your registered Contrast environments. You don't need to leave your editor to find out which of your services are exposed. Once matched, the editor queries `list_critical_vulnerabilities` to highlight hot spots in your codebase. You can tackle the most severe security issues before you even commit your branch.

Audit your deployment environments from the editor

Cursor uses this MCP server to call `list_monitored_servers` and verify where your code is running without opening a browser tab. You see which staging or production servers have active Contrast agents installed. By combining this with `list_vulnerability_traces`, your agent warns you if you are about to deploy to a server that has unresolved vulnerabilities. It keeps your deployment pipeline clean and secure.

Setup guide

Set up Contrast 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 Contrast 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 Contrast Security transactions." If the MCP tools are loaded correctly, Cursor will call the Contrast Security tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

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

Common questions about Contrast Security MCP in Cursor

Create a `.cursor/mcp.json` file in your project root or add it globally in your Cursor settings. Paste the server configuration, and your Cursor agent will instantly have access to the security tools.

Cursor can write the exact code to fix the alert in Agent mode. It pulls the trace via `get_vulnerability_details`, refactors your local file, and lets you review the diff before saving.

No, it runs asynchronously. Cursor only calls tools like `list_applications` when you explicitly ask it to check your security posture or fix a specific bug.

Yes. You can ask Cursor to show only the worst issues. The agent will run `list_critical_vulnerabilities` or `search_vulnerabilities` to filter out the noise and focus on critical threats.

Your credentials stay locked in Vinkius's secure sandbox. Cursor only receives the specific JSON payloads returned by tools like `get_vulnerability_details` to build your code context, ensuring your security metadata never leaks.
