Antigravity

Antigravity lets you manage Buffer directly from Google's agent-first IDE.

Draft posts, check your queue, and manage your social media workflow without leaving your IDE.

Connect Buffer to Antigravity with your API key.

Setup

Get Your API Key

You need an API key to integrate Buffer with Antigravity.

API Key Get API Key →

Your key is shared with the API Explorer and will prefill the configuration steps below.

Add the Buffer MCP server

Run the following command to add the Buffer MCP server to Antigravity:

agy mcp add --header "Authorization: Bearer YOUR_API_KEY" buffer https://mcp.buffer.com/mcp

Or open ~/.gemini/config/mcp_config.json and add the following configuration:

{
  "mcpServers": {
    "buffer": {
      "disabled": false,
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      },
      "serverUrl": "https://mcp.buffer.com/mcp"
    }
  }
}

Restart Antigravity

Quit Antigravity and open it again so it picks up the new server.

Check the connection

Go to Settings → Customizations and confirm Buffer appears in the MCP servers list. Refresh the list if it isn't there yet.
