Official Firecrawl MCP Server - Adds powerful web scraping to Cursor, Claude and any other LLM clients.
A Model Context Protocol (MCP) server implementation that integrates with Firecrawl for web scraping capabilities.
Big thanks to @vrknetha, @cawstudios for the initial implementation!
env FIRECRAWL_API_KEY=fc-YOUR_API_KEY npx -y firecrawl-mcp
npm install -g firecrawl-mcp
Configuring Cursor 🖥️ Note: Requires Cursor version 0.45.6+
To configure FireCrawl MCP in Cursor:
env FIRECRAWL_API_KEY=your-api-key npx -y firecrawl-mcpIf you are using Windows and are running into issues, try
cmd /c "set FIRECRAWL_API_KEY=your-api-key && npx -y firecrawl-mcp"
Replace your-api-key with your FireCrawl API key.
After adding, refresh the MCP server list to see the new tools. The Composer Agent will automatically use FireCrawl MCP when appropriate, but you can explicitly request it by describing your web scraping needs. Access the Composer via Command+L (Mac), select "Agent" next to the submit button, and enter your query.
Add this to your ./codeium/windsurf/model_config.json:
{
"mcpServers": {
"mcp-server-firecrawl": {
"command": "npx",
"args": ["-y", "firecrawl-mcp"],
"env": {
"FIRECRAWL_API_KEY": "YOUR_API_KEY_HERE"
}
}
}
}
To install FireCrawl for Claude Desktop automatically via Smithery:
npx -y @smithery/cli install @mendableai/mcp-server-firecrawl --client claude

Add this to your claude_desktop_config.json:
{
"mcpServers": {
"mcp-server-firecrawl": {
"command": "npx",
"args": ["-y", "firecrawl-mcp"],
"env": {
"FIRECRAWL_API_KEY": "YOUR_API_KEY_HERE",
"FIRECRAWL_RETRY_MAX_ATTEMPTS": "5",
"FIRECRAWL_RETRY_INITIAL_DELAY": "2000",
"FIRECRAWL_RETRY_MAX_DELAY": "30000",

}
}
The server includes several configurable parameters that can be set via environment variables. Here are the default values if not configured:
const CONFIG = {
retry: {
maxAttempts: 3, // Number of retry attempts for rate-limited requests
initialDelay: 1000, // Initial delay before first retry (in milliseconds)
maxDelay: 10000, // Maximum delay between retries (in milliseconds)
backoffFactor: 2, // Multiplier for exponential backoff
},
credit: {
warningThreshold: 1000, // Warn when credit usage reaches this level
criticalThreshold: 100, // Critical alert when credit usage reaches this level
},
};
These configurations control:
Retry Behavior
Credit Usage Monitoring
The server utilizes FireCrawl's built-in rate limiting and batch processing capabilities:
firecrawl_scrape)Scrape content from a single URL with advanced options.
{
"name": "firecrawl_scrape",
"arguments": {
"url": "https://example.com",
"formats": ["markdown"],
"onlyMainContent": true,
"waitFor": 1000,
"timeout": 30000,
"mobile": false,
"includeTags": ["article", "main"],
"excludeTags": ["nav", "footer"],
"skipTlsVerification": false
}
}
firecrawl_batch_scrape)Scrape multiple URLs efficiently with built-in rate limiting and parallel processing.
{
"name": "firecrawl_batch_scrape",
"arguments": {
"urls": ["https://example1.com", "https://example2.com"],
"options": {
"formats": ["markdown"],

}
}
}

}
],
"isError": false
}

"price": 99.99,
"description": "This is an example product description"
}
}
],
"isError": false
}
urls: Array of URLs to extract information fromprompt: Custom prompt for the LLM extractionsystemPrompt: System prompt to guide the LLMschema: JSON schema for structured data extractionallowExternalLinks: Allow extraction from external linksenableWebSearch: Enable web search for additional contextincludeSubdomains: Include subdomains in extractionWhen using a self-hosted instance, the extraction will use your configured LLM. For cloud API, it uses FireCrawl's managed LLM service.
The server includes comprehensive logging:
Example log messages:
[INFO] FireCrawl MCP Server initialized successfully
[INFO] Starting scrape for URL: https://example.com
[INFO] Batch operation queued with ID: batch_1
[WARNING] Credit usage has reached warning threshold
[ERROR] Rate limit exceeded, retrying in 2s...
The server provides robust error handling:
Example error response:
{
"content": [
{
"type": "text",
"text": "Error: Rate limit exceeded. Retrying in 2 seconds..."
}
],
"isError": true
