FAQ from Firecrawl Simple MCP Server

How do I configure the Firecrawl Simple MCP Server?

Set environment variables such as FIRECRAWL_API_URL, FIRECRAWL_API_KEY, FIRECRAWL_API_TIMEOUT, FIRECRAWL_SERVER_PORT, FIRECRAWL_TRANSPORT_TYPE, and FIRECRAWL_LOG_LEVEL. Default values are provided in the configuration table.

Why was crawl functionality removed?

Crawl was removed to prevent context overflow for LLMs (too much information), because crawling runs asynchronously (unsuitable for synchronous MCP), and to align with primary documentation. For multi-page scraping, use the scrape tool with individual URLs or implement a custom solution.

What should I do if I get connection errors?

Verify the Firecrawl Simple API is running, check the API URL (including /v1), and ensure no network restrictions block the connection.

What transport types are supported?

The server supports stdio (default) and sse transport types. Set FIRECRAWL_TRANSPORT_TYPE to switch between them.

How can I resolve authentication errors?

Ensure FIRECRAWL_API_KEY is correct and matches the API’s requirements. Contact the API administrator if needed.
