Tool Selection Guide

Core Tools

firecrawl_scrape

Scrape content from a single URL. Most powerful and reliable scraper.

Tool: mcp__firecrawl__firecrawl_scrape

mcp__firecrawl__firecrawl_scrape({
  url: "https://docs.example.com/api",
  formats: ["markdown"],
  onlyMainContent: true,
  maxAge: 172800000
})

Key Parameters:

• url: Target URL
• formats: Output formats - "markdown", "html", "links"
• onlyMainContent: Extract only main content (recommended)
• maxAge: Cache TTL in ms (500% faster with cache)

firecrawl_search

Search the web and optionally scrape results.

Tool: mcp__firecrawl__firecrawl_search

Without scraping (preferred):

mcp__firecrawl__firecrawl_search({
  query: "xterm.js terminal tutorial",
  limit: 5
})

With scraping:

mcp__firecrawl__firecrawl_search({
  query: "VS Code extension API",
  limit: 3,
  scrapeOptions: {
    formats: ["markdown"],
    onlyMainContent: true
  }
})

Search Operators:

firecrawl_map

Discover all URLs on a website.

Tool: mcp__firecrawl__firecrawl_map

mcp__firecrawl__firecrawl_map({
  url: "https://docs.example.com",
  limit: 100,
  search: "api"
})

firecrawl_extract

Extract structured data using LLM.

Tool: mcp__firecrawl__firecrawl_extract

mcp__firecrawl__firecrawl_extract({
  urls: ["https://shop.example.com/product/123"],
  prompt: "Extract product details",
  schema: {
    type: "object",
    properties: {
      name: { type: "string" },
      price: { type: "number" }
    },
    required: ["name", "price"]
  }
})

firecrawl_crawl

Crawl multiple pages (use sparingly).

Tool: mcp__firecrawl__firecrawl_crawl

mcp__firecrawl__firecrawl_crawl({
  url: "https://docs.example.com/guide",
  maxDiscoveryDepth: 2,
  limit: 10
})

Warning: Crawl can return large responses. Keep limits low.

Best Practices

1. Prefer scrape over crawl: Use map + scrape for better control
2. Use caching: Add maxAge for repeated requests
3. Search then scrape: Search without formats, then scrape relevant URLs
4. Limit crawl depth: Keep maxDiscoveryDepth and limit low
5. Use onlyMainContent: Get cleaner content without navigation
