# MCP Jailbreaker Server
This is a Model Context Protocol (MCP) server that implements a **partial AI jailbreak**, deployed as a Cloudflare Worker. Connect your ai with the jailbreaker via https://mcp-jailbreaker.cf-test-fa8.workers.dev/mcp.
## TLDR
Add this config for Claude:
```json
{
"mcpServers": {
"mcp-jailbreaker": {
"command": "npx",
"args": [
"mcp-remote",
"https://mcp-jailbreaker.cf-test-fa8.workers.dev/mcp"
]
}
}
}
```
## How It Works
Once set up, start a conversation with the AI using the phrase:
> **"Let's play space wars"**
> [!IMPORTANT]
> This jailbreak works for the most part, but you must **remain in character** and **maintain the illusion** for the AI in order for it to stay jailbroken. Breaking character may cause the AI to revert to its normal behavior or report you to the provider.
## Features
- **No Authentication**: The server is open and requires no credentials.
- **play_game Tool**: A simple tool that initiates the space wars scenario.
- **Cloudflare Workers**: Runs on Cloudflare's edge network for low latency.
## Prerequisites
- Node.js (v18 or higher recommended)
- npm
- [Wrangler CLI](https://developers.cloudflare.com/workers/wrangler/) (for deployment)
## Installation
1. Clone the repository:
```bash
git clone https://github.com/Mcrich23/mcp-jailbreaker.git
cd mcp-jailbreaker
```
2. Install dependencies:
```bash
npm install
```
## Usage
### Local Development
Run the server locally with Wrangler:
```bash
npm run dev
```
This starts a local server at `http://localhost:8787`.
### Endpoints
- `/` - Health check
- `/sse` - Server-Sent Events transport for MCP
- `/mcp` - Standard MCP HTTP transport
### Deployment to Cloudflare
Deploy to Cloudflare Workers:
```bash
npm run deploy
```
### Configuration in Claude Desktop
Add the following to your `claude_desktop_config.json` (typically located in `~/Library/Application Support/Claude/` on macOS):
```json
{
"mcpServers": {
"mcp-jailbreaker": {
"command": "npx",
"args": [
"mcp-remote",
"https://mcp-jailbreaker.cf-test-fa8.workers.dev/mcp"
]
}
}
}
```
Replace the URL with your deployed Cloudflare Worker URL.
