Connect HeySale to Google Antigravity

Custom MCP
  1. 1Open Antigravity's MCP settings for your surface (IDE, CLI or SDK) and add a custom server.
  2. 2Use the configuration below.
  3. 3Ask the agent to add a HeySale salesperson to the project.

Configuration

{
  "mcpServers": {
    "heysale": {
      "type": "http",
      "url": "https://hey.sale/mcp"
    }
  }
}

No API key is needed to create a salesperson. Reading a salesperson's conversations, leads or results requires the website owner's own HeySale API key.

  • · Antigravity documents MCP separately for the IDE, CLI and SDK; field names can differ slightly between them — follow Google's page for your surface.

Or start here, right now

Give us your website address. We read it, build your salesperson, and show her to you before you sign up for anything.

Things to say to Google Antigravity

  • “Add an AI salesperson to this website.”
  • “Install HeySale and verify the embed is on the deployed site.”

Why this pairing works

The site gets built in minutes; the selling still has to happen after the visitor lands.
HeySale reads the finished site and answers from it — no separate knowledge base to maintain.
Leads arrive with the whole conversation attached, so you know what they actually wanted.

HeySale runs one MCP server for every assistant: https://hey.sale/mcp over Streamable HTTP (remote MCP).
