This gives Claude access to Exa's neural search and Firecrawl's scraping through x402-protected APIs. It's noticeably better than the built-in WebSearch for semantic queries (think "startups building AI agents" instead of keyword matching) and handles JavaScript-heavy or blocked sites that WebFetch can't reach. You get search, similar page discovery, content extraction, and multi-page crawling, with prices ranging from $0.002 to $0.10 per request. The async crawl pattern for whole sites is a bit fiddly (start crawl, poll for results), but the neural search quality and ability to scrape paywalled content make it worth keeping around for research-heavy tasks.
