MCP Configuration Sample

Here is a sample configuration snippet for setting up an MCP server within your environment:

{
  "mcpServers": {
    "[server-name]": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-[name]"],
      "env": {
        "API_KEY": "your-api-key"
      }
    }
  }
}

This example provides a clear template for extending the server setup, using environment variables and npm commands to ensure seamless integration.
