DomainCat

DomainCat watches the things that quietly break websites: SSL certificates, the origin certificates behind Cloudflare and other proxies, domain registration expiry, DNS changes and email blacklists. This connector lets Claude read and manage your DomainCat account in plain English.

Ask "what expires in the next 30 days?", "is anything blacklisted?", "which origin certs are close to expiring?" or "summarize the Acme Corp group." Claude can also run a live check on any domain or IP without saving it, which is handy for troubleshooting.

With read & write access, Claude can add domains (singly or in bulk, into a group with tags), update labels, groups and tags, refresh checks, and create groups and tags. Removing domains always asks for your confirmation.

You decide what Claude can touch. When you connect, DomainCat asks whether to grant read-only or read & write access, and whether to allow all domains or just one group, which suits MSPs and agencies managing many clients. Every change Claude makes is recorded in an audit log, and you can revoke the connection anytime in DomainCat Settings.

Free DomainCat accounts can connect read-only. Pro and MSP plans add write access and single-group connections.
