Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

Check domain availability for $ARGUMENTS using the domain-suite-mcp server.

Steps

Call list_providers to see which providers are configured and what pricing sources are available.

Parse the input:

If a full domain is given (e.g. myapp.com), split into name + TLD
If a name only (e.g. myapp), check .com, .io, .dev, .co by default
If TLDs are specified (e.g. myapp com,io,net), use those

Call check_availability with the domain name, tlds array, and provider (use the first configured provider that supports pricing, if any).

Present results in a clear table:

Domain | Available | Price (reg) | Price (renewal) | Source
Highlight available domains
If no provider is configured, note that pricing requires API credentials

If any domains are available and the user seems interested in registering, ask if they'd like to proceed and suggest using /domain-register.

Notes

check_availability works with zero configuration via RDAP/WHOIS — no API key needed for availability
Pricing is only returned when a provider (Porkbun, Namecheap, GoDaddy) is configured
For premium domains the premium field will be true — warn the user, prices may be much higher
