Antigravity Docs

A Model Context Protocol (MCP) server that provides AI agents with up-to-date documentation for the Antigravity IDE. It includes a built-in scraper to automatically fetch and update the latest docs directly into a local knowledge base.

Features

• Server: Provides docs://index to list pages, and tools list_document_names and search_docs to find relevant information.
• Scraper & Extractor: Python scripts powered by Playwright to crawl the Antigravity Docs site and extract readable Markdown.
• Auto-Updater: A single bash script update.sh to fully automate the parsing of the site and injecting the content into the knowledge_base/ folder.

Installation

1. Clone the repository

git clone https://github.com/imgt511/Antigravity_Docs_MCP.git
cd Antigravity_Docs_MCP

2. Setup the Python Environment (For the Scraper)

The scraper uses Python and Playwright. Build a local virtual environment:

python3 -m venv venv
source venv/bin/activate
pip install playwright
playwright install

3. Setup the Node Environment (For the Server)

The MCP server itself is served using the official MCP Node SDK.

npm install

Usage

Connecting the MCP Server to Antigravity IDE

Point your Antigravity IDE settings (or any other MCP-compatible client) to execute the Node.js server:

{
  "mcpServers": {
    "antigravity-docs": {
      "command": "node",
      "args": ["/absolute/path/to/Antigravity_Docs_MCP/mcp_server.js"]
    }
  }
}

How to Refresh the Knowledge Base

When new updates are released for the Antigravity IDE, you can easily pull the latest documentation yourself!

The Easy Way

Simply run the included update script from inside the project directory:

./update.sh

What it does:

1. Runs scraper.py to find any new pages on the website.
2. Runs extractor.py to overwrite your knowledge_base/ folder with the newest text.
3. Your MCP server instantly starts using the new files. There is no need to restart anything!
