Modern bug hunting is evolving beyond manual request manipulation and repetitive testing. As web applications become more complex and assessment timelines shrink, security researchers need smarter ways to identify vulnerabilities efficiently without sacrificing accuracy.

By combining Burp Suite MCP Server with Cursor AI, security researchers or bug hunters can leverage AI-assisted analysis, automate repetitive tasks, and accelerate vulnerability discovery directly from Burp Suite data. In this blog, we'll explore how this powerful integration can streamline web application security testing and enhance modern bug hunting workflows.

Introduction to Burp Model Context Protocol (MCP) Server

The Burp MCP (Model Context Protocol) Server acts as a bridge between Burp Suite and AI-powered assistants such as Cursor AI. It exposes Burp Suite functionality through a standardized protocol, allowing AI clients to interact directly with HTTP traffic, testing tools, and project data. This enables security professionals to automate repetitive tasks, analyze requests and responses more efficiently, and accelerate web application security assessments through AI-assisted workflows.

Prerequisites

Before configuring the Burp MCP Server and Cursor AI integration, ensure the following components are installed and properly configured in your testing environment:

  • Burp Suite Professional (recommended for full functionality; Community Edition supports limited features)
  • Burp MCP Server Extension installed from the Burp Suite BApp Store
  • Cursor AI installed (Linux, Windows, or macOS)
  • An authorized target application for security testing and validation

Having these prerequisites in place will ensure a smooth setup process and allow you to fully leverage AI-assisted web application security testing workflows.

Installing Burp MCP Server

Step 1: Install the MCP Extension in Burp Suite

  1. Launch Burp Suite.
  2. Navigate to Extensions → BApp Store.
  3. Search for "MCP".
  4. Click Install and wait for the extension to be installed successfully.
None

Once the installation is complete, a new MCP tab will appear in the Burp Suite toolbar.

None

Step 2: Configure the MCP Server

  1. Open the MCP tab.
  2. Verify that the MCP Server is enabled. If it is disabled, enable it manually.
  3. Scroll down and click Extract Server Proxy JAR to download the MCP proxy JAR file required for external AI client integration.
None

Note the MCP Server URL displayed in Burp Suite. By default, the server runs on:

http://127.0.0.1:9876/
None

This endpoint will be used later to establish communication between Burp Suite and Cursor AI.

Connecting Cursor AI to Burp MCP Server

Step 1: Open MCP Settings in Cursor

  1. Launch Cursor AI.
  2. Navigate to Settings → Tools & MCPs.
  3. Click Add Custom MCP.
None

Step 2: Configure the MCP Connection

Add the following configuration:

{
  "mcpServers": {
    "burp": {
      "command": "<path to Java executable packaged with Burp>",
      "args": [
          "-jar",
          "/path/to/mcp/proxy/jar/mcp-proxy.jar",
          "--sse-url",
          "<your Burp MCP server URL configured in the extension>"
      ]
    }
  }
}

Configuration Details

Replace the following placeholders with values from your environment:

<path-to-java-executable>

  • Full path to the Java executable used by Burp Suite.
  • Example:
C:\\Program Files\\Java\\jdk-21\\bin\\java.exe

/path/to/mcp-proxy.jar

  • Full path to the MCP Proxy JAR file downloaded from the Burp MCP extension.
  • Example:
C:\\Users\\subha\\OneDrive\\Documents\\mcp-proxy.jar

<Burp-MCP-Server-URL>

  • URL where the Burp MCP Server is running.
  • Default value:
http://127.0.0.1:9876/

Important:_ When specifying Windows file paths in the JSON configuration, use double backslashes (\) instead of single backslashes (). JSON treats the backslash as an escape character, so double backslashes are required for paths to be parsed correctly._

Example Configuration

{
  "mcpServers": {
    "burp": {
      "command": "C:\\Program Files\\Java\\jdk-21\\bin\\java.exe",
      "args": [
        "-jar",
        "C:\\Users\\subha\\OneDrive\\Documents\\mcp-proxy.jar",
        "--sse-url",
        "http://127.0.0.1:9876/"
      ]
    }
  }
}

After updating the configuration:

  1. Save the file (Ctrl + S).
  2. Restart Cursor AI.
None

Step 3: Verify the Connection

After restarting:

  1. Open Settings → Tools & MCPs.
  2. Locate the Burp MCP configuration.
  3. Confirm that the connection status shows a green indicator, indicating successful communication between Cursor AI and Burp Suite.
None

Verifying the Integration

Once the MCP connection is established, you can verify that Cursor AI can communicate with Burp Suite.

  1. Open a new AI chat in Cursor (Ctrl + I).
  2. Execute the following prompt:
Burp MCP: status
None

If Cursor successfully retrieves information from Burp Suite, the integration is working correctly and your AI-assisted web application security testing environment is ready for use.

You can now leverage Cursor AI to interact with Burp data, analyze requests and responses, generate payloads, automate repetitive tasks, and streamline your web application security testing workflow.

What You Can Automate with Burp MCP and Cursor AI

By integrating Burp MCP Server with Cursor AI, security testers can streamline several time-consuming tasks:
