Usage

Configuration

This server is designed to be configured through MCP client settings. Environment variables are passed through the MCP configuration rather than using a .env file.

Required environment variables:

• DATABASE_URL: Your PostgreSQL connection string
• BUSINESS_ID: Default business ID (can be overridden per tool call)

Note: Business IDs are passed dynamically as parameters to each tool call, allowing the server to handle multiple businesses without hardcoded configuration.

Running the Server

npm start

Or for development:

npm run dev

MCP Configuration

To use this server with Claude Desktop or other MCP clients, add the following configuration to your MCP settings:

{
  "mcpServers": {
    "appointment-mcp": {
      "command": "node",
      "args": [
        "/path/to/appointment_mcp/build/index.js"
      ],
      "env": {
         "DATABASE_URL": "postgresql://username:password@localhost:5432/database",
         "BUSINESS_ID": "your-default-business-id"
       }
    }
  }
}

Or using npx (recommended for published packages):

{
  "mcpServers": {
    "appointment-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "appointment-mcp-server@latest"
      ],
      "env": {
         "DATABASE_URL": "postgresql://username:password@localhost:5432/database",
         "BUSINESS_ID": "your-default-business-id"
       }
    }
  }
}

Local Development

For local development, you can run the server directly:

npm start

Or for development with auto-rebuild:

npm run dev

Note: When running locally for development, you'll need to set environment variables manually or use a .env file.

• Date format must be YYYY-MM-DD
• Time format must be HH:MM (24-hour format)
• Environment variables must be configured through MCP client settings
