Gemini CLI - SendKit

Gemini CLI is Google’s command-line AI assistant. You can connect it to SendKit’s MCP server to manage your email infrastructure with natural language.

Prerequisites

Gemini CLI installed
A SendKit API key with Full permission

Setup

Open the settings file

Edit your Gemini CLI settings at ~/.gemini/settings.json:

{
  "mcpServers": {
    "sendkit": {
      "httpUrl": "https://mcp.sendkit.dev/sendkit",
      "headers": {
        "Authorization": "Bearer sk_your_api_key_here"
      }
    }
  }
}

Replace sk_your_api_key_here with your actual API key from the SendKit dashboard.

For project-level configuration, create .gemini/settings.json in your project root instead.

Restart Gemini CLI

Close and reopen Gemini CLI to load the new configuration.

Verify the connection

Ask Gemini to interact with your SendKit account:

List all my SendKit senders

Gemini CLI uses "httpUrl" for HTTP streaming servers (not "url"). The "url" field is used for SSE transport only.
