JEB MCP

A Model Context Protocol (MCP) server for JEB reverse engineering platform. This server enables AI assistants like Claude to interact with JEB through the standardized MCP protocol.

Installation

``bash
npm install @xi0yu/jebmcp
`

Quick Start

$3

To use this with Claude Desktop, add the following to your claude_desktop_config.json:

Windows: %APPDATA%/Claude/claude_desktop_config.json
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

`json
{
"mcpServers": {
"jeb": {
"command": "npx",
"args": ["-y", "@xi0yu/jebmcp"]
}
}
}
`

$3

Add the following to your VS Code User Settings (JSON) by pressing Ctrl + Shift + P and typing "Preferences: Open User Settings (JSON)":

`json
{
"mcp": {
"servers": {
"jeb": {
"command": "npx",
"args": ["-y", "@xi0yu/jebmcp"]
}
}
}
}
`

Alternatively, create a .vscode/mcp.json file in your workspace:

`json
{
"servers": {
"jeb": {
"command": "npx",
"args": ["-y", "@xi0yu/jebmcp"]
}
}
}
`

Usage

$3

`bash
npx @xi0yu/jebmcp
`

$3

`bash


STDIO mode (default)

npx @xi0yu/jebmcp --transport stdio

HTTP mode

npx @xi0yu/jebmcp --transport http --port 16162

SSE mode

npx @xi0yu/jebmcp --transport sse --port 16162
`

$3

`bash
npx @xi0yu/jebmcp --jeb-host 127.0.0.1 --jeb-port 16161 --jeb-path /mcp
`

Configuration

$3

You can configure the proxy using environment variables:

`json
{
"mcpServers": {
"jeb": {
"command": "npx",
"args": ["-y", "@xi0yu/jebmcp"],
"env": {
"JEB_HOST": "127.0.0.1",
"JEB_PORT": "16161",
"LOG_ENABLED": "true"
}
}
}
}
`

$3

- JEB_HOST: JEB server host (default: 127.0.0.1)
- JEB_PORT: JEB server port (default: 16161)
- JEB_PATH: JEB MCP endpoint path (default: /mcp)
- LOG_ENABLED: Enable detailed logging (default: false)

Requirements

- Node.js: Version 16.0.0 or higher
- Python: Version 3.8 or higher
- JEB: JEB reverse engineering platform with MCP support

Troubleshooting

$3

Problem: Error message: Cannot find module 'node:path'

Solution: Upgrade your Node.js installation to version 18 or later. Make sure the command in config points to the correct Node.js version.

$3

Problem: python3: command not found or similar Python-related errors

Solution:
1. Ensure Python is installed and available in your PATH
2. Install required Python dependencies: pip install fastmcp>=0.1.0
3. On Windows, the proxy automatically detects whether to use python or python3

$3

Problem: Unable to connect to JEB server

Solution:
1. Ensure JEB is running and MCP server is enabled
2. Verify the JEB MCP server is listening on the correct host and port
3. Check firewall settings if connecting to a remote JEB instance

$3

Enable detailed logging by setting the LOG_ENABLED environment variable:

`json
{
"mcpServers": {
"jeb": {
"command": "npx",
"args": ["-y", "@xi0yu/jebmcp"],
"env": {
"LOG_ENABLED": "true"
}
}
}
}
`

Development

$3

`bash
git clone https://github.com/xi0yu/jeb-mcp.git
cd jeb-mcp-npm
npm install
pip install -r requirements.txt
`

$3

`bash
