Installation
Prerequisites
Ensure that the following prerequisites are met before building and installing the extension:
1. **Java**: Java must be installed and available in your system's PATH. You can verify this by running java --version in your terminal.
2. **jar Command**: The jar command must be executable and available in your system's PATH. You can verify this by running jar --version in your terminal. This is required for building and installing the extension.
Building the Extension
1. **Clone the Repository**: Obtain the source code for the MCP Server Extension.
2. **Navigate to the Project Directory**: Move into the project's root directory.
3. **Build the JAR File**: Use Gradle to build the extension.
This command compiles the source code and packages it into a JAR file located in build/libs/burp-mcp-all.jar.
Loading the Extension into Burp Suite
1. **Open Burp Suite**: Launch your Burp Suite application.
2. **Access the Extensions Tab**: Navigate to the Extensions tab.
3. **Add the Extension**:
- Click on Add.
- Set Extension Type to Java.
- Click Select file ... and choose the JAR file built in the previous step.
- Click Next to load the extension.
Upon successful loading, the MCP Server Extension will be active within Burp Suite.
Configuration
Configuring the Extension
Configuration for the extension is done through the Burp Suite UI in the MCP tab.
- **Toggle the MCP Server**: The Enabled checkbox controls whether the MCP server is active.
- **Enable config editing**: The Enable tools that can edit your config checkbox allows the MCP server to expose tools which can edit Burp configuration files.
- **Advanced options**: You can configure the port and host for the MCP server. By default, it listens on http://127.0.0.1:9876.
Claude Desktop Client
To fully utilize the MCP Server Extension with Claude, you need to configure your Claude client settings appropriately.
The extension has an installer which will automatically configure the client settings for you.
1. Currently, Claude Desktop only support STDIO MCP Servers
for the service it needs.
This approach isn't ideal for desktop apps like Burp, so instead, Claude will start a proxy server that points to the
Burp instance,
which hosts a web server at a known port (localhost:9876).
2. **Configure Claude to use the Burp MCP server**
You can do this in one of two ways:
- **Option 1: Run the installer from the extension**
This will add the Burp MCP server to the Claude Desktop config.
