Firecrawl MCP

Overview

This skill enables web scraping and content extraction using Firecrawl through MCP. Firecrawl provides powerful capabilities for scraping single pages, crawling entire websites, searching with content extraction, and extracting structured data.

When to Use This Skill

Scraping content from single web pages
Crawling multiple pages on a website
Searching the web with automatic content extraction
Discovering all URLs on a website
Extracting structured data (prices, names, details)

Tool Selection Guide

Task	Tool	Notes
Single page content	`firecrawl_scrape`	Fast, reliable
Find URLs on site	`firecrawl_map`	Discovery only
Web search	`firecrawl_search`	With optional scraping
Multiple pages	`firecrawl_map` + `firecrawl_scrape`	Better than crawl
Structured data	`firecrawl_extract`	Uses LLM extraction
Full site crawl	`firecrawl_crawl`	Use with caution

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:

Operator	Example	Description
`""`	`"exact phrase"`	Exact match
`-`	`-deprecated`	Exclude term
`site:`	`site:github.com`	Specific site
`inurl:`	`inurl:docs`	URL contains
`intitle:`	`intitle:tutorial`	Title contains

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

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