Configuration

The plugin connects to the QubitOn MCP server at https://mcp.qubiton.com/mcp (streamable HTTP) using the apikey header for authentication. The MCP config (mcp.json) references a QUBITON_API_KEY environment variable so you don't have to paste the key into config files:

{
  "mcpServers": {
    "qubiton": {
      "url": "https://mcp.qubiton.com/mcp",
      "headers": {
        "apikey": "${QUBITON_API_KEY}"
      }
    }
  }
}
