Claude Code’s WebFetch Can’t Run JavaScript: Firecrawl MCP Gives It Real Web Scraping in 1 Command (No API Key)

You ask Claude Code to pull the plans from a pricing page, and it hands back a vague summary instead of the table. Its built-in WebFetch doesn’t run JavaScript, and the agent gets a processed summary rather than the page itself. JS-rendered docs, pricing tables, and “read these 30 pages and compare them” jobs are where it falls apart.

Firecrawl MCP fixes that with one command. It gives the agent a proper web toolkit (~7.5k GitHub stars, maintained by the Firecrawl team). It can search the web, scrape any URL into clean markdown or JSON, map every URL on a site, crawl whole doc sections, and parse PDFs. The part most guides miss is that there’s now a hosted keyless endpoint . Search, scrape, and parse work with no API key, no account, and no Node.js install.

What the full guide covers:

  • What You’ll Need
  • Step-by-Step Setup
  • What Each Piece Does
  • Verify It’s Actually Working

The commands, our own test notes, and the troubleshooting steps are in the full guide, which we keep up to date:
