Binary Ninja MCP server

This MCP server allows Cline to analyze binaries using Binary Ninja functionality. It works as a bridge between Cline and Binary Ninja, enabling you to leverage Binary Ninja's analysis capabilities within the Cline environment.

Installation Requirements

Before setting up the server, ensure you have:

• Binary Ninja with a valid license
• Node.js installed
• Cline installed and configured

Setup Instructions

Install the Binary Ninja MCP Plugin

1. Install the latest version of the Binary Ninja MCP Plugin from https://github.com/fosdickio/binary_ninja_mcp

Start the Binary Ninja Server

2. Open your binary file in Binary Ninja
3. Start the MCP server from within Binary Ninja

Run the HTTP Server

4. Open a terminal and run the HTTP server:

python binary_ninja_mcp_http_server.py --port 8088

Start the Node.js Bridge

5. Open another terminal and start the Node.js component:

npm start

Configuring Cline

After setting up the servers, you need to configure Cline to use the MCP server:

1. Open Cline
2. Add the following tool configuration:

{
  "mcpServers": {
    "BN MCP": {
      "command": "node",
      "args": ["/home/matteius/binary_ninja_cline/bn_cline_mcp/binaryninja-mcp-bridge.js"],
      "env": {
        "BN_HTTP_SERVER": "http://localhost:8088"
      },
      "autoApprove": [],
      "disabled": false,
      "timeout": 30
    }
  }
}

Configuration Options

• command: The command to run (Node.js in this case)
• args: Path to the MCP bridge JavaScript file
• env: Environment variables, including the HTTP server address
• timeout: Maximum time in seconds to wait for a response
• disabled: Set to true to temporarily disable the server

Make sure to adjust the path in the args field to match your actual installation location.

Usage

Once configured, you can use Binary Ninja's analysis capabilities through Cline. The MCP server will handle communication between Cline and Binary Ninja, allowing you to analyze binaries more effectively.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
