Antigravity - SendKit

Antigravity is Google’s AI coding agent. You can connect it to SendKit’s MCP server to manage your email infrastructure with natural language.

Prerequisites

Antigravity installed
A SendKit API key with Full permission

Setup

Open the MCP configuration file

Edit your Antigravity MCP configuration file and add the SendKit server:

{
  "mcpServers": {
    "sendkit": {
      "serverUrl": "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.

Restart Antigravity

Restart Antigravity to load the new MCP configuration.

Verify the connection

Ask Antigravity to interact with your SendKit account:

Antigravity uses "serverUrl" for remote MCP connections (not "url"). This is the same format used by Windsurf.
