## About

Domainee is a custom domains API for SaaS with a native MCP server. 50 domains and 100 GB are free.

Connect a customer's hostname and get back the CNAME target, force DNS and SSL probes, debug "my domain isn't working" tickets, and manage webhook endpoints, all on the same key, rate limits, and workspace as the REST API. Hosted and stateless: nothing to deploy.

Connect your Domainee account and 11 workspace tools cover domains, webhook endpoints, and DNS verification. 16 diagnostic tools need no account at all: SSL checks, DNS and TXT record lookups, WHOIS, CNAME resolution, HTTP headers, DNS propagation, redirects, SPF/DKIM/DMARC, domain age and availability, subdomain finding, reverse IP, and website status.

## How to use

1. **Add it in ChatGPT** Open Domainee in ChatGPT's Plugin directory (button above), select + to add it and sign in if asked.

2. **Use it in a chat** Type @ in the composer and pick Domainee, or start your message with its name. ChatGPT may also suggest it when it fits what you ask.

## Example prompts

- "Why isn't my customer's custom domain working?"
- "Check the SSL certificate on example.com and when it expires"
- "Add a customer's domain and give me the DNS record they need"
