If you've come across mcp-on-edge-dpls0cs9fl6a.edgeone.dev and are wondering whether it's safe, the honest answer is that there's not enough trustworthy information available to say yes. This domain presents itself as a tool for generating globally accelerated websites using something called edge functions, but it operates with almost total anonymity. There is no company name, no team, no email address, and no privacy policy explaining what happens to the code or data you provide.
For a legitimate SaaS product, even a small one, you'd typically find some kind of about page or social media account. Here, neither exists. The domain is brand new, has no history recorded in the Wayback Machine, and its WHOIS ownership records are inaccessible. The site also accepts older, insecure encryption methods and lacks basic security headers that protect users from common web attacks.
When a tool asks you to generate or run code, you need to know who made it and what they do with your input. Right now, mcp-on-edge-dpls0cs9fl6a.edgeone.dev doesn't provide that. Until it does, treating it with caution is the sensible approach.
