An MCP server prototype for evaluating hidden-payload delivery to LLMs in agentic IDEs (e.g., Cursor). Built exclusively for ML security research and defensive testing - no malicious use.
The MCP server is hosted on the cloud for free thanks to FastMCP Cloud. You can view the current deployment of the server at https://fastmcp.cloud/ronin-mcp/ronin-mcp-v1/deployments. Whenever you commit and push a change to the main branch, it will automatically build and deploy onto the cloud. Please note that this link is only accessible to the owners of this project.
Go to File -> Preferences -> Cursor Settings -> Tools & MCP -> Installed MCP Servers. Create a new MCP server configuration using the following json:
{
"mcpServers": {
"ronin-mcp-v1": {
"url": "https://ronin-mcp-v1.fastmcp.app/mcp",
"headers": {}
}
}
}
Then, go back to Installed MCP Servers and refresh ronin-mcp-v1 until the light is green and it shows the tools associated with the Ronin MCP server. In Cursor, open the AI Panel and try the following prompt to see if the server connection is successful:
