About Firecrawl MCP Server
Connect your AI agent to Firecrawl — the most popular web scraping API built specifically for AI and LLM applications.
LangChain's ecosystem of 500+ components combines seamlessly with Firecrawl through native MCP adapters. Connect 4 tools via the Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures — with LangSmith tracing giving full visibility into every tool call, latency, and token cost.
What you can do
- Scrape Pages — Extract clean Markdown from any URL. Firecrawl handles JavaScript rendering, anti-bot protection, cookie banners, and dynamic content automatically
- Search the Web — Search and scrape in one call. Get Google-like search results with full page content already extracted
- Crawl Websites — Recursively crawl entire sites, following internal links. Perfect for indexing documentation, blogs, or product catalogs
- Map Sites — Discover all URLs on a domain without scraping content. Understand site structure before deciding what to extract
The Firecrawl MCP Server exposes 4 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
