How to Set Up and Use Binary Ninja MCP
Binary Ninja MCP is a plugin, MCP server, and bridge that integrates the Binary Ninja reverse engineering platform with AI assistants, enabling natural language control of binary analysis workflows. It allows AI agents to decompile functions, read disassembly, navigate cross-references, manage type information, rename symbols, patch bytes, and add comments — all through an MCP-compatible client such as Claude or Cursor. Security researchers and CTF players use it to accelerate reverse engineering by delegating repetitive analysis tasks to AI while retaining full control over the Binary Ninja session.
Prerequisites
- Binary Ninja installed with a valid license (binary.ninja)
- The binary-ninja-mcp plugin installed via Binary Ninja's Plugin Manager (Plugins > Manage Plugins) or manually copied to the plugins folder
- Node.js 18+ and npm/npx for the recommended npm-based MCP bridge
- A binary file open in Binary Ninja before connecting the MCP client
- An MCP-compatible client such as Claude Desktop, Cursor, Cline, Windsurf, or Claude Code
Install the Binary Ninja plugin
Open Binary Ninja and go to Plugins > Manage Plugins. Search for 'binary-ninja-mcp' and install it. Alternatively, manually copy the plugin files to the Binary Ninja user plugins folder.
# Plugin Manager path: Plugins > Manage Plugins > Search 'binary-ninja-mcp'
# Or manually copy to:
# macOS: ~/Library/Application Support/Binary Ninja/plugins/
# Windows: %APPDATA%\Binary Ninja\plugins\
# Linux: ~/.binaryninja/plugins/Open a binary and activate the MCP bridge
Open the binary file you want to analyze in Binary Ninja. Once open, click the activation button at the bottom-left corner of the Binary Ninja window to start the local MCP bridge server. It listens on localhost:9009 by default.
Configure your MCP client using the npm bridge
Add binary-ninja-mcp to your MCP client configuration using the npx command. Specify --host and --port to match the bridge server started by the plugin.
{
"mcpServers": {
"binary-ninja-mcp": {
"command": "npx",
"args": ["-y", "binary-ninja-mcp", "--host", "localhost", "--port", "9009"]
}
}
}Restart your MCP client
Save the configuration and restart Claude Desktop, Cursor, or your other MCP client. The AI should now be able to call Binary Ninja analysis functions on the open binary.
Verify the connection by asking for binary info
Ask your AI assistant to list the functions or entry points in the currently open binary. A successful response confirms the MCP bridge is communicating with Binary Ninja.

Example reverse engineering tasks you can delegate to your AI assistant via the Binary Ninja MCP server.
- "Decompile the main function and explain what it does"
- "List all strings in this binary that look like URLs or IP addresses"
- "Rename all functions and variables in sub_401234 to descriptive names based on their behavior"
- "Analyze this binary from its entry point, follow function calls, and tell me if it looks malicious"
- "Find all cross-references to the strcmp function and analyze what strings are being compared"
- "Add comments to the decompiled output of the validate_license function explaining each block"Troubleshooting Binary Ninja MCP
MCP client cannot connect to the bridge on localhost:9009
Ensure you have clicked the activation button in Binary Ninja's bottom-left corner to start the bridge server. If Binary Ninja is not running or no binary is open, the bridge will not start. Verify the port is not blocked by a firewall or already in use by another process.
Plugin does not appear in Binary Ninja's Plugin Manager
Check that your Binary Ninja is up to date. Try manually installing by copying the plugin files to the user plugins directory. On macOS: ~/Library/Application Support/Binary Ninja/plugins/. Restart Binary Ninja after copying. Check the Binary Ninja log (View > Log) for plugin load errors.
npx binary-ninja-mcp fails or returns package not found
Try specifying the full package name: 'npx -y binary-ninja-mcp'. If the npm package is not available, use the Python bridge alternative: configure the MCP server to run the binja_mcp_bridge.py script directly using the Python interpreter in the plugin's virtual environment.
