git clone https://github.com/wangyafu/haiguitangmcp/
cd haiguitangmcp
uv sync

Configuration

After installation, you need to configure your MCP client to connect to the server.

VSCode Configuration

Add the following to your VSCode configuration:

"mcp": {
    "servers": {
        "haiguitang-mcp": {
            "type": "stdio",
            "command": "uv",
            "args": [
                "--directory",
                "E:\\haiguitangmcp\\haiguitang_mcp",
                "run",
                "server.py"
            ]
        }

Game Rules

• Players ask yes/no questions to narrow down possibilities and discover the full story
• The host answers with "yes," "no," "both yes and no," or "irrelevant"
• Players can attempt to solve the puzzle by starting their message with "汤底" (solution)
• The host will confirm when players have correctly identified the key scenario

Tips for Playing

• Start with basic questions about the number of people involved, cause of death, etc.
• Pay attention to every detail in the puzzle description as they may be crucial clues

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
