MCP^2(MCPSQ)

MCP^2(MCPSQ) is a simple MCP server to discover and manage MCP servers. See our website mcpsq.xyz for more information.

Usage

npm start

Local Development

Prerequisites

• Node.js (v18 or higher)
• Cursor editor

Installation

1. Clone the repository:

git clone https://github.com/xinbenlv/mcpsq.git
cd mcpsq

2. Install dependencies:

npm install

Running the Server

Start the MCP server locally:

# Production mode
npm start

# Development mode with auto-reload
npm run dev

# Build TypeScript to JavaScript
npm run build

The server will start on http://localhost:3000 and provide:

• SSE endpoint at GET /mcp
• Message handling at POST /messages

Configuring Cursor MCP Integration

To use this MCP server with Cursor, add the following configuration to your Cursor MCP settings:

Option 1: Global Configuration

Create or edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "mcpsq": {
      "url": "http://localhost:3000/mcp"
    }
  }
}

Option 2: Project-specific Configuration

Create .cursor/mcp.json in your project root:

{
  "mcpServers": {
    "mcpsq": {
      "url": "http://localhost:3000/mcp"
    }
  }
}

Available MCP Tools

Once configured, the following tools will be available in Cursor:

• find-mcp-server: Search for MCP servers relevant to your query
• add-mcp-server-to-cursor: Add an MCP server to your Cursor configuration
• list-current-mcp-servers: List all currently configured MCP servers
• remove-mcp-server-from-cursor: Remove an MCP server from your configuration

Testing the Integration

1. Start the MCPSQ server locally
2. Configure Cursor with the MCP settings above
3. Restart Cursor or reload the MCP configuration
4. In Cursor chat, try asking: "Find MCP servers for database management"
5. The MCPSQ tools should appear in the available tools list

Development Scripts

# Start the server in production mode
npm start

# Start the server in development mode with auto-reload
npm run dev

# Build TypeScript to JavaScript
npm run build

# Clean build directory
npm run clean

# Validate data files
npm run validate:data

# Type checking without emitting files
npm run typecheck

Development Workflow

1. Development: Use npm run dev for development with automatic restart on file changes
2. Type Checking: Run npm run typecheck to check for TypeScript errors without building
3. Building: Use npm run build to compile TypeScript to JavaScript (automatically cleans first)
4. Production: Use npm start to run the compiled TypeScript directly with tsx

Troubleshooting

• Server not starting: Check if port 3000 is available
• Cursor not connecting: Verify the MCP configuration file path and JSON syntax
• Tools not appearing: Check Cursor's MCP logs in the output panel
• TypeScript errors: Run npm run typecheck to see detailed error messages
