MCP Firecrawl

A production-ready Model Context Protocol (MCP) server that integrates with the Firecrawl API to give AI assistants the power to scrape, crawl, and search the web.

Works with Claude Desktop, Cursor, VS Code (Cline/Roo Code), Continue, OpenAI Agents SDK, and any other MCP-compatible AI tool.

Quick Start

# 1. Clone
git clone https://github.com/YOUR_USERNAME/MCP.git
cd MCP

# 2. Install
npm install

# 3. Configure
cp .env.example .env

Usage

Command Line Test

# List available tools
node test-mcp.mjs tools

# Scrape a website
node test-mcp.mjs scrape https://example.com

# Search the web
node test-mcp.mjs search "latest TypeScript news"

With OpenAI Agents SDK (TypeScript)

import { Agent, run, MCPServerStdio } from "@openai/agents";

const mcp = new MCPServerStdio({
  name: "Firecrawl",
  fullCommand: "node dist/server.js",
  env: { FIRECRAWL_API_KEY: "fc-..." },
});

await mcp.connect();

const agent = new Agent({
  name: "Web Assistant",
  instructions: "Use tools to scrape, crawl, and search the web.",
  mcpServers: [mcp],
});

const result = await run(agent, "Scrape https://example.com");
console.log(result.finalOutput);
await mcp.close();

Integration with AI Tools

Claude Desktop

Add to %APPDATA%\Claude\claude_desktop_config.json:

{
  "mcpServers": {
    "firecrawl": {
      "command": "node",
      "args": ["C:/path/to/MCP/dist/server.js"],
      "env": {
        "FIRECRAWL_API_KEY": "fc-..."
      }
    }
  }
}

Cursor

Settings → Features → MCP → Add Server:

Name: firecrawl
Type: command
Command: node "C:/path/to/MCP/dist/server.js"
Environment: FIRECRAWL_API_KEY=fc-...

VS Code + Cline / Roo Code

File: .vscode/cline_mcp_settings.json

{
  "mcpServers": {
    "firecrawl": {
      "command": "node",
      "args": ["C:/path/to/MCP/dist/server.js"],
      "env": { "FIRECRAWL_API_KEY": "fc-..." },
      "disabled": false,
      "autoApprove": []
    }
  }
}

Continue (VS Code / JetBrains)

File: ~/.continue/config.json

  "experimental": {
    "mcpServers": {
      "firecrawl": {
        "command": "node",
        "args": ["C:/path/to/MCP/dist/server.js"],
        "env": { "FIRECRAWL_API_KEY": "fc-..." }
      }
    }
  }
}

opencode

File: ./opencode.json

{
  "mcp": {
    "firecrawl": {
      "type": "local",
      "command": ["node", "MCP/dist/server.js"],
      "enabled": true,
      "env": { "FIRECRAWL_API_KEY": "fc-..." }
    }
  }
}

HTTP Mode (Streamable HTTP)

Can't use stdio? Run the server as an HTTP endpoint instead:

npm run start:http
# Listening on http://127.0.0.1:3001/mcp

Then connect any MCP client to that URL.
