I cannot scrape https://example.com from my n8n MCP Client Exec tool

[lbois]

Hello

I am working on a workflow in n8n to scrape using Firecrawl the page https://example.com/

I have two MCP Clients (List and Exec) that use the firecrawl_scrape. But I have always as output message. Cannot scrape the page. I do not understand, because my configuration seems correct.

The body is :

{
"url": "https://example.com/",
"formats": ["markdown"],
"scrapeOptions": {
"onlyMainContent": true,
"excludeTags": ["script", "style", "head"]
}
}
}

Please help me .

Laurent
