Webスクレイピング、検索、クロール、マッピング機能を提供するClaude Codeプラグイン。
Turn any website into clean, LLM-ready markdown or structured data — directly from Claude Code.
This plugin adds the Firecrawl CLI as a skill to Claude Code, giving it the ability to scrape, search, crawl, and map the web.
All operations include automatic JavaScript rendering, anti-bot handling, and proxy rotation.
In Claude Code, run /plugin and search for firecrawl, then select it to install.
The plugin requires the Firecrawl CLI to be installed globally:
npm install -g firecrawl-cli
Run the following to authenticate via your browser:
firecrawl login --browser
Or authenticate with an API key directly:
firecrawl login --api-key "fc-YOUR-API-KEY"
You can also set the key as an environment variable (add to ~/.zshrc or ~/.bashrc for persistence):
export FIRECRAWL_API_KEY=fc-YOUR-API-KEY
Get your free API key at: https://firecrawl.dev/app/api-keys
firecrawl --status
You should see your authentication status, concurrency limit, and remaining credits.
Once installed, Claude Code will automatically use Firecrawl for web tasks. Just ask naturally:
Search the web:
Search for "best practices for React testing" and compile the key recommendations
Scrape a page:
Scrape https://docs.firecrawl.dev/introduction and summarize the key points
Discover site structure:
Map all URLs on https://firecrawl.dev
Research a topic:
Research the latest developments in AI agents and give me a summary
The plugin uses these Firecrawl CLI commands under the hood:
| Command | Description |
|---|---|
firecrawl search "query" | Search the web (supports --sources, --scrape, --tbs for time filters) |
firecrawl scrape <url> | Scrape a single page to markdown |
firecrawl map <url> | Discover all URLs on a site |
firecrawl browser launch/execute/list/close | Manage cloud browser sessions and execute Playwright code |
firecrawl --status | Check auth status, concurrency, and credits |
Results are saved to a .firecrawl/ directory in your project to keep Claude Code's context window clean:
.firecrawl/search-react_server_components.json
.firecrawl/docs.github.com-actions-overview.md
.firecrawl/firecrawl.dev.md
| Variable | Required | Description |
|---|---|---|
FIRECRAWL_API_KEY | Yes (if not using firecrawl login) | Your Firecrawl API key |
FIRECRAWL_API_URL | No | Custom API endpoint (for self-hosted instances) |
Firecrawl can be self-hosted. Set FIRECRAWL_API_URL to point to your instance:
export FIRECRAWL_API_URL=https://your-firecrawl-instance.com
See the Firecrawl documentation for self-hosting instructions.
