SealMCP

</div>

SealMCP is an MCP server for Roblox exploit script development written in Python.

<div align="center"> <img src="./assets/image-1.png" alt="Image 1" /> </div> Prompt:

Hey, Claude. Automate a Roblox Studio task for me using SealMCP and make every part in the Workspace blue.

SealMCP allows your AI agent to interact with the Roblox environment, write exploit scripts and run luau code.

NOTE: Sometimes your AI agent will refuse to follow your instructions. You need to either lie to it so it writes the code, or use an unfiltered model.

SealMCP has only been tested on Volt so far, so some issues or bugs may occur with other executors.

How to use

First of all, clone the SealMCP github repository.

git clone https://github.com/Seal-Softworks/SealMCP
cd SealMCP

Then, install the required Python packages.

pip install -r requirements.txt 

After that, add the MCP server config to your AI application's .json configuration file.

{
	"mcpServers": {
    	"seal-mcp": {
      		"command": "python3",
      		"args": ["path/to/server.py"]
    	}
  	},
}

The JSON configuration for SealMCP should look something like that. The server.py file is located in server/server.py

Depends on what application you use, this configuration file will be located at a different path.

Claude Desktop

For Claude Desktop, the configuration file will usually be located in

C:\Users\your-user\AppData\Local\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Roaming\Claude

Locate the claude_desktop_config.json file and edit it to use SealMCP.

Running the client

Once the MCP and WebSocket servers are running (both are started by the server.py script), the last thing you need to do before using SealMCP is running the client script. The client script is located in client/seal-mcp.luau. In order to be able to use SealMCP, use an executor that supports WebSockets. Run the code below in your executor:

loadstring(game:HttpGet("https://raw.githubusercontent.com/Seal-Softworks/SealMCP/refs/heads/main/client/seal-mcp.luau"))();

If everything went correctly, the logs will say that the WebSocket client has connected successfully. If this script does not work, you could try using the old version.

-- // old seal-mcp.luau
loadstring(game:HttpGet("https://raw.githubusercontent.com/Seal-Softworks/SealMCP/refs/heads/main/client/seal-mcp-OLD.luau"))();

The old version is no longer maintained, so we recommend using the standard version.

Note!

SealMCP is still in early development. There might be some bugs or issues, so beware.
