Bring Data Extraction
to LangChain
Learn how to connect Firecrawl to LangChain and start using 6 AI agent tools in minutes. Fully managed, enterprise secure, and ready to use without writing a single line of code.
What is the Firecrawl MCP Server?
Connect your Firecrawl account to any AI agent and take full control of your web data acquisition and recursive crawling workflows through natural conversation.
What you can do
- Web Scrape Orchestration — Scrape any single URL programmatically into high-fidelity Markdown, excluding boilerplate content like headers and footers automatically
- Recursive Crawling — Programmatically discover and scrape all subpages starting from a root URL to build comprehensive knowledge bases and RAG pipelines
- Site Mapping — Quickly identify all reachable links on a domain without full content extraction to understand website structures and hierarchies
- Visual Capture — Capture full-page screenshots of any URL directly through your agent to maintain a visual record of web data
- Usage Monitoring — Track your Firecrawl credit usage, remaining limits, and active crawl job statuses in real-time
How it works
1. Subscribe to this server
2. Retrieve your API Key from the Firecrawl dashboard (API Keys section)
3. Start scraping and crawling the web from Claude, Cursor, or any MCP client
No more manual copy-pasting from websites or complex BeautifulSoup scripts. Your AI acts as your dedicated web data engineer.
Who is this for?
- AI Developers — build RAG applications by programmatically ingesting clean, structured web data via natural language
- Research Teams — automate data gathering from across the web for market analysis and competitor monitoring
- Content Creators — instantly convert articles into Markdown and capture website screenshots without leaving your workspace

Frequently asked questions
How do I find my Firecrawl API Key?
Log in to your Firecrawl dashboard, and navigate to the API Keys section to copy your unique token.
Can I scrape content excluding headers and footers?
Yes! The scrape_url tool includes an onlyMainContent parameter. When set to true, Firecrawl uses AI to extract only the core article or page content.
How long does a recursive crawl take?
Crawl time depends on the site size and depth. Use the get_crawl_status tool to monitor progress and retrieve results once the job is complete.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
