Install PineLabs Plural PG — Payment Gateway MCP Server in Gemini CLI

What you need first

• Gemini CLI, installed.
• Nothing else: the server runs on its publisher's machines and Gemini CLI connects to it.
• Your own values for YOUR_X_CLIENT_ID,YOUR_X_CLIENT_SECRET.

Steps

1. Open ~/.gemini/settings.json, or create it. For one project only, use .gemini/settings.json in that project.
2. Add this block. If the file already has mcpServers, add only the entry inside it.

{
  "mcpServers": {
    "pinelabs-online-mcp": {
      "httpUrl": "https://mcp.pinelabs.com/mcp",
      "headers": { "X-Client-Id": "YOUR_X_CLIENT_ID", "X-Client-Secret": "YOUR_X_CLIENT_SECRET" }
    }
  }
}

3. Replace YOUR_X_CLIENT_ID,YOUR_X_CLIENT_SECRET with your own values.
4. Save the file and restart Gemini CLI.

Check it worked

Ask Gemini CLI: List the tools of pinelabs-online-mcp.

If it does not start

401 Unauthorized

The endpoint wants a sign-in or a key. Sign in when Gemini CLI asks, or check the value in place of the placeholder.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
