Features

MCP Server + Ghidra Plugin

• Decompile and analyze binaries in Ghidra
• Automatically rename methods and data
• List methods, classes, imports, and exports

Installation

Installing via Smithery

To install GhidraMCP for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @DaCodeChick/GhidraMCP --client claude

Prerequisites

• Install Ghidra
• Python3
• MCP SDK

Ghidra

First, download the latest release from this repository. This contains the Ghidra plugin and Python MCP client. Then, you can directly import the plugin into Ghidra.

Plugin Installation

1. Run Ghidra
2. Select File -> Install Extensions
3. Click the + button
4. Select the GhidraMCP-1-2.zip (or your chosen version) from the downloaded release
5. Restart Ghidra

Plugin Configuration and Activation

Important: The GhidraMCP plugin operates within Ghidra's CodeBrowser tool, not the Project Manager.

6. Create or open a Ghidra project in the Project Manager
7. Import and open a binary for analysis (the plugin requires an active program)
8. Open the CodeBrowser tool (double-click your imported program or use Tools → CodeBrowser)
9. In the CodeBrowser, navigate to File → Configure → Developer
10. Enable the GhidraMCPPlugin in the Developer tools list
11. The HTTP server will start automatically when the plugin is enabled with an active program

Server Configuration

• Optional: Configure the server port in CodeBrowser via Edit → Tool Options → GhidraMCP HTTP Server
• Default server address: http://127.0.0.1:8080/
• The HTTP server only runs when:
  • CodeBrowser is open
  • A program is loaded
  • GhidraMCPPlugin is enabled

Understanding Ghidra's Architecture

Ghidra uses a multi-tool architecture:

• Project Manager: Manages projects and imports binaries
• CodeBrowser: The main analysis tool where most plugins operate
• Other Tools: Various specialized analysis tools

The GhidraMCP plugin specifically integrates with the CodeBrowser tool's analysis capabilities.

Troubleshooting

Plugin not visible in File → Configure → Developer:

• Ensure you've restarted Ghidra after installing the extension
• Verify you're in the CodeBrowser tool, not the Project Manager
• Check that a program is loaded and active

HTTP server not responding:

• Confirm the plugin is enabled in CodeBrowser's Developer tools
• Verify a binary program is loaded and analyzed
• Check the server port configuration in Tool Options
• Ensure no firewall is blocking localhost connections

"Connection refused" errors:

• The HTTP server only starts when CodeBrowser is open with the plugin enabled
• Close and reopen CodeBrowser if the server seems stuck
• Verify the port matches your MCP client configuration

Typical Workflow

1. Start Ghidra Project Manager
2. Import your target binary (File → Import File)
3. Open CodeBrowser by double-clicking the imported program
4. Enable GhidraMCP plugin (File → Configure → Developer)
5. Start your MCP client (Claude Desktop, Cline, etc.)
6. Begin reverse engineering with AI assistance

The HTTP server runs continuously while CodeBrowser remains open with the plugin enabled.

MCP Clients

Theoretically, any MCP client should work with ghidraMCP. Three examples are given below.

Example 1: Claude Desktop

To set up Claude Desktop as a Ghidra MCP client, go to Claude -> Settings -> Developer -> Edit Config -> claude_desktop_config.json and add the following:

{
  "mcpServers": {
    "ghidra": {
      "command": "python",
      "args": [
        "/ABSOLUTE_PATH_TO/bridge_mcp_ghidra.py",
        "--ghidra-server",
        "http://127.0.0.1:8080/"
      ]
    }
  }
}

Alternatively, edit this file directly:

/Users/YOUR_USER/Library/Application Support/Claude/claude_desktop_config.json

The server IP and port are configurable and should be set to point to the target Ghidra instance. If not set, both will default to localhost:8080.

Example 2: Cline

To use GhidraMCP with Cline, this requires manually running the MCP server as well. First run the following command:

python bridge_mcp_ghidra.py --transport sse --mcp-host 127.0.0.1 --mcp-port 8081 --ghidra-server http://127.0.0.1:8080/

The only required argument is the transport. If all other arguments are unspecified, they will default to the above. Once the MCP server is running, open up Cline and select MCP Servers at the top.

Then select Remote Servers and add the following, ensuring that the url matches the MCP host and port:

1. Server Name: GhidraMCP
2. Server URL: http://127.0.0.1:8081/sse

Example 3: 5ire

Another MCP client that supports multiple models on the backend is 5ire. To set up GhidraMCP, open 5ire and go to Tools -> New and set the following configurations:

1. Tool Key: ghidra
2. Name: GhidraMCP
3. Command: python /ABSOLUTE_PATH_TO/bridge_mcp_ghidra.py

Example 4: VSCode (GitHub Copilot)

GitHub Copilot's agent mode can connect to MCP servers over both stdio and sse. To set up GhidraMCP as a "tool" in VSCode's Copilot chat, you need to first make sure you are in "Agent" mode. Then, click on the tools icon in the chat box:

In the drop down menu that appears, select "Add More Tools" and then "Add MCP Server"

Select "Command (stdio)" and enter python3 C:\path\to\bridge_mcp_ghidra.py --ghidra-server http://localhost:8080/ as the command. Make sure to replace the path to the Python script with the actual path on your machine.

Lastly, give your MCP connection a name for VSCode.

Building from Source

Build with Gradle by simply running:

gradle

The generated zip file includes the built Ghidra plugin and its resources. These files are required for Ghidra to recognize the new extension.
