Quick Start

1. Get your Firecrawl API key from the developer portal

2. Set your API key:

Unix/Linux/macOS (bash/zsh):

bash export FIRECRAWL_API_KEY=your-api-key

Windows (Command Prompt):

cmd set FIRECRAWL_API_KEY=your-api-key

Windows (PowerShell):

powershell $env:FIRECRAWL_API_KEY = "your-api-key"

Alternative: Using .env file (recommended for development):

```bash # Install dotenv npm install dotenv

# Create .env file echo "FIRECRAWL_API_KEY=your-api-key" > .env ```

Then in your code:

javascript import dotenv from 'dotenv'; dotenv.config();

1. Run the server:

bash mcp-server-firecrawl
