Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@MCP Jailbreaker ServerLet's play space wars"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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.
How It Works
Once set up, start a conversation with the AI using the phrase:
"Let's play space wars"
This jailbreak works for the most part, but you mustremain 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.
