drwho.me MCP server

drwho.me is a free website full of small tools for looking up domains, checking email setup, and doing everyday developer chores like decoding a JWT or formatting JSON. Its MCP server hands those same tools to your AI assistant, so you can just ask instead of clicking around. It is handy for anyone who works with websites, domains, or email and wants quick answers without hunting through menus.

What this MCP server does

You ask your AI something like "check the email setup for example.com" or "decode this JWT". The AI sends that request to the drwho.me MCP server. The server runs the check or utility and sends the result back. Your AI then explains it to you in the chat. You never have to visit a website or copy results by hand.

What you can do with it

• Check a domain's DNS records, mail servers, and DNSSEC
• Look at SPF, DMARC, and DKIM email authentication settings
• Inspect a site's TLS certificate, response headers, and redirects
• See what robots.txt, sitemap, and llms.txt say about a site
• Look up WHOIS registration data and subdomains from certificate logs
• Decode a JWT, format JSON, or encode and decode Base64 and URLs
• Generate a UUID or parse a User-Agent string

Try asking your AI

• “Run a full domain check on example.com and tell me what is wrong”
• “Does example.com have SPF and DMARC set up correctly?”
• “Decode this JWT for me: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...”
• “Format this messy JSON and generate a UUID for me”

What it gives back to you

You get back plain answers in the chat: lists of DNS records, a graded line for each email or TLS check, decoded JWT contents, formatted JSON, or a generated UUID. For domain checks, you also get a link to the full report on Domain Posture. The AI can summarise everything in a sentence or two if you ask.
