Frequently asked questions
How is Spider different from Firecrawl?
Spider is built in Rust and optimized for raw speed and volume — it can crawl 100K+ pages per second, making it 10-20x faster than Firecrawl for large-scale operations. Spider also offers lower per-page costs at high volume, built-in stealth mode with fingerprint rotation, and multiple request modes (HTTP, Smart, Chrome). Firecrawl excels at simplicity and LLM-specific features like JSON extraction.
What output formats does Spider support?
Spider supports Markdown, HTML, raw HTML, plain text, JSON (structured extraction), screenshots, and PDF output. You can specify the desired format via the return_format parameter in each request.
How does Spider pricing work?
Spider offers 500 free credits to get started (no credit card required). Paid plans are usage-based with credits consumed per page scraped. The Starter plan begins at $15/month with 12,000 credits. Enterprise plans offer custom pricing with dedicated infrastructure and unlimited concurrency.
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.
