firecrawl-cli（Firecrawl CLI 搜索）

Firecrawl CLI

Use the firecrawl CLI to fetch and search the web. Firecrawl returns clean markdown optimized for LLM context windows, handles JavaScript rendering, bypasses common blocks, and provides structured data.

Installation

Check status, auth, and rate limits:

firecrawl --status

Output when ready:

  🔥 firecrawl cli v1.0.2

  ● Authenticated via FIRECRAWL_API_KEY
  Concurrency: 0/100 jobs (parallel scrape limit)
  Credits: 500,000 remaining

• Concurrency: Max parallel jobs. Run parallel operations close to this limit but not above.
• Credits: Remaining API credits. Each scrape/crawl consumes credits.

If not installed: npm install -g firecrawl-cli

Always refer to the installation rules in rules/install.md for more information if the user is not logged in.

Authentication

If not authenticated, run:

firecrawl login --browser

The --browser flag automatically opens the browser for authentication without prompting.

Organization

Create a .firecrawl/ folder in the working directory unless it already exists to store results. Add .firecrawl/ to the .gitignore file if not already there. Always use -o to write directly to file (avoids flooding context):

# Search the web (most common operation)
firecrawl search "your query" -o .firecrawl/search-{query}.json

# Search with scraping enabled
firecrawl search "your query" --scrape -o .firecrawl/search-{query}-scraped.json

# Scrape a page
firecrawl scrape https://example.com -o .firecrawl/{site}-{path}.md

Examples:

.firecrawl/search-react_server_components.json
.firecrawl/search-ai_news-scraped.json
.firecrawl/docs.github.com-actions-overview.md
.firecrawl/firecrawl.dev.md

Reading Scraped Files

NEVER read entire firecrawl output files at once unless explicitly asked - they can be 1000+ lines. Instead, use grep, head, or incremental reads:

# Check file size and preview structure
wc -l .firecrawl/file.md && head -50 .firecrawl/file.md

# Use grep to find specific content
grep -n "keyword" .firecrawl/file.md
grep -A 10 "## Section" .firecrawl/file.md

Parallelization

Run multiple scrapes in parallel using & and wait:

# Parallel scraping (fast)
firecrawl scrape https://site1.com -o .firecrawl/1.md &
firecrawl scrape https://site2.com -o .firecrawl/2.md &
firecrawl scrape https://site3.com -o .firecrawl/3.md &
wait

For many URLs, use xargs with -P for parallel execution:

cat urls.txt | xargs -P 10 -I {} sh -c 'firecrawl scrape "{}" -o ".firecrawl/$(echo {} | md5).md"'

Combining with Other Tools

# Extract URLs from search results
jq -r '.data.web[].url' .firecrawl/search-query.json

# Get titles from search results
jq -r '.data.web[] | "\(.title): \(.url)"' .firecrawl/search-query.json

# Count URLs from map
firecrawl map https://example.com | wc -l
