Development/Code Analysis & GenerationBinary NinjaReverse EngineeringPluginAutomation

The MCP (Model Context Protocol) Server for Binary Ninja allows external tools to interact with Binary Ninja for tasks like renaming symbols and retrieving code snippets. It supports both UI plugin and headless modes, providing a versatile interface for reverse engineering workflows.

Installation

Server Setup

There are two ways to run the MCP server:

  1. Binary Ninja UI Plugin:

    • Install the plugin via Binary Ninja's plugin manager
    • The MCP server will start automatically when first file is loaded.
      • Auto start is configurable via Settings - MCP Server - Auto Start
      • Listen port is configurable via Settings - MCP Server - Server port number
    • All opened files are exposed to separate resources, see Available Resources section below

  2. Binary Ninja Headless Mode:

    uvx binaryninja-mcp install-api  # only run once
uvx binaryninja-mcp server <filename> [filename]...
    • filename could be any binary files or BNDB, like in UI mode, all opened files are available to the MCP client.
    • Server runs on default port 7000
    • Use --port flag to specify a different port

MCP Client Setup

  1. Claude Desktop (stdio relay client): Configure the client to connect via stdio transport using built-in relay.

    {
  "mcpServers": {
    "binaryninja": {
      "command": "uvx",
      "args": ["binaryninja-mcp", "client"]
    }
  }
}

  2. Cherry Studio:

    • SSE endpoint (recommanded): URL: http://localhost:7000/sse
    • stdio client:
      • Command: uvx
      • Arguments: 
        binaryninja-mcp
client

Add --port 12345 to both server and client command line if you prefer to run MCP server on port other than default.

Available Tools for MCP Clients

The MCP server provides the following tools:

  • rename_symbol: Rename a function or a data variable
  • pseudo_c: Get pseudo C code of a specified function
  • pseudo_rust: Get pseudo Rust code of a specified function
  • high_level_il: Get high level IL of a specified function
  • medium_level_il: Get medium level IL of a specified function
  • disassembly: Get disassembly of a function or specified range
  • update_analysis_and_wait: Update analysis for the binary and wait for completion
  • get_triage_summary: Get basic information from BinaryNinja Triage view
  • get_imports: Get dictionary of imported symbols
  • get_exports: Get dictionary of exported symbols
  • get_segments: Get list of memory segments
  • get_sections: Get list of binary sections
  • get_strings: Get list of strings found in the binary
  • get_functions: Get list of functions
  • get_data_variables: Get list of data variables

Available Resources for MCP Clients

MCP Resources can be accessed via URIs in the format: binaryninja://{filename}/{resource_type}

The server provides these resource types for each binary:

  • triage_summary: Basic information from BinaryNinja Triage view
  • imports: Dictionary of imported symbols/functions
  • exports: Dictionary of exported symbols/functions
  • segments: List of memory segments
  • sections: List of binary sections
  • strings: List of strings found in the binary
  • functions: List of functions
  • data_variables: List of data variables

Development

uv is the recommanded package management tool for this project.

Clone directory to Binary Ninja Plugin Directory

git clone https://github.com/MCPPhalanx/binaryninja-mcp.git "${env:APPDATA}\Binary Ninja\plugins\MCPPhalanx_binaryninja_mcp"

Setup Python Environment

Binary Ninja API must be installed into virtualenv manually.

uv venv
uv sync --dev
# install binaryninja API
binaryninja-mcp install-api
# check API is correctly installed
uv run python -c 'import binaryninja as bn; print(f"ui_enabled={bn.core_ui_enabled()}")'

Setup MCP Client for Development

For MCP clients with stdio transport like Claude Desktop, change working directory to development folder.

{
  "mcpServers": {
    "binaryninja": {
      "command": "uv",
      "args": [
        "--directory",
        "C:/path/to/binaryninja-mcp",
        "run",
        "binaryninja-mcp",
        "client"
      ]
    }
  }
}

SSE-enabled MCP clients can connect using: http://localhost:7000/sse

Version Bump

The PyPI package version is automatically derived from Binary Ninja's plugin.json (using package.json format), maintaining version consistency between the BN plugin and PyPI package.

# bump alpha version
uvx hatch version a

# bump release version
uvx hatch version minor,rc
uvx hatch version release
