Google Antigravity

Plugin Keenable is in the Plugin marketplace in Antigravity. The plugin connects Antigravity’s agents to Keenable’s hosted MCP server and adds a skill for everyday web lookups. It needs no account and no API key. → keenableai/keenable-antigravity on GitHub

Install from the marketplace

In the Antigravity app, open the Customizations tab in the left sidebar.
Click Marketplace and find Keenable. The card lists what the plugin bundles.
Click + on the card to install it.

Installed plugins appear under Customizations → Installed, where a toggle turns them off and the card’s Uninstall removes them. A plugin installed in the app also shows up in the Antigravity CLI. Then ask something that needs the live web, for example:

Find the release notes for the libraries in this project since our pinned
versions and list the breaking changes.

Antigravity may show an Authenticate button next to the Keenable server. The tools work without signing in, on the shared public tier.

What you get

	What it does
`search_web_pages`	Ranked web results with an excerpt of each page, narrowed by site or publication date when needed.
`fetch_page_content`	Any URL as clean markdown, or only the part an extraction prompt asks for.
`keenable-web` skill	When to search, when to read a page, how to cite.

Other ways to install

Antigravity CLI

agy plugin install https://github.com/keenableai/keenable-antigravity

From the repository. Clone it into your global plugins folder, or into .agents/plugins/ of a workspace to enable it for that project only:

git clone https://github.com/keenableai/keenable-antigravity ~/.gemini/config/plugins/keenable

Gemini CLI. The same repository is a Gemini CLI extension:

gemini extensions install https://github.com/keenableai/keenable-antigravity

MCP server only. To add the two tools without the skill, put this in ~/.gemini/config/mcp_config.json and restart Antigravity, which reads the file at startup:

{
  "mcpServers": {
    "keenable": {
      "serverUrl": "https://api.keenable.ai/mcp-public"
    }
  }
}

Higher rate limits

The plugin sends no credentials, so it runs on the shared public tier at lower rate limits. To search on your own account, create an API key in the console and add a second server with it in ~/.gemini/config/mcp_config.json:

{
  "mcpServers": {
    "keenable-account": {
      "serverUrl": "https://api.keenable.ai/mcp-public",
      "headers": {
        "X-API-Key": "keen_<your_key>"
      }
    }
  }
}

The skill works with either server. See Authentication.

Data

The plugin talks only to https://api.keenable.ai/mcp-public over HTTPS. Search queries and requested URLs are sent to Keenable with an X-Keenable-Title: antigravity header that identifies the plugin’s traffic. It sends no credentials, runs no local code or shell commands and reads no local files. → Full MCP server reference
