MCP Web Search & Scrape in Antigravity

Add Firecrawl web scraping and search to Google Antigravity

Add Firecrawl's search, scrape, crawl, and browser tools to Google Antigravity via MCP.

Quick Setup

1. Get Your API Key

Sign up at firecrawl.dev/app and copy your API key.

2. Add Firecrawl to Antigravity

Open Antigravity settings (Cmd/Ctrl + ,), search for MCP Servers, and add a new server with:

{
"mcpServers": {
  "firecrawl": {
    "command": "npx",
    "args": ["-y", "firecrawl-mcp"],
    "env": {
      "FIRECRAWL_API_KEY": "fc-YOUR-API-KEY"
    }
  }
}
}

Replace fc-YOUR-API-KEY with your Firecrawl API key.

3. Reload Antigravity

Reload the window (Cmd/Ctrl + Shift + P → Reload Window). The agent now has Firecrawl's web tools available.

Quick Demo

In an Antigravity agent chat:

Search the web for "Vercel AI SDK v5 release notes" and summarize.

Scrape https://docs.firecrawl.dev/ai-onboarding and list every linked guide.

Crawl https://example.com and extract every page title.

Antigravity routes those tool calls through Firecrawl MCP automatically.

Remote Hosted URL (no Node.js required)

{
"mcpServers": {
  "firecrawl": {
    "url": "https://mcp.firecrawl.dev/fc-YOUR-API-KEY/v2/mcp"
  }
}
}

Troubleshooting

• Server shows as "failed", check the MCP output panel for stderr. Most failures are a missing API key or npx not on PATH.
• Tools not invoked, explicitly mention Firecrawl (e.g., "Use Firecrawl to scrape…") in your first prompt so the agent picks the right tool.
