Domain Check MCP

Add domains you control, verify TXT records, and create an MCP token for AI-assisted checks.

Free self review

Domains your AI client is allowed to check

Free plan: 10 verified domains and 350 checks per day. Publish the TXT challenge, then connect an MCP client.

Tokens are shown once. Treat them like passwords.

Connect your AI

Point your AI client at dom4in

Your AI client talks to the MCP server directly. You don't call anything by hand. Paste the setup prompt into Claude, Cursor, or any MCP client, add the token you created above, and it finds the tools on its own.

MCP server URL https://dom4in.net/mcp

Auth: send the bearer token from Create MCP token above in the Authorization header. Once connected your AI gets five read-only tools: domain_brief, dns_records, mail_health, rdap_lookup, and manual_check_steps.
