Announce: "I'm using the check-domain skill to check domain availability."

Check Domain Availability

Check whether a domain name is available for registration and suggest alternatives if it's taken.

Required: Instant Domain Search MCP

This skill requires the instant-domain-search MCP server. If the MCP tools (mcp__instant-domain-search__*) are not available, stop immediately and tell the user:

Instant Domain Search MCP is not configured. Install it from https://instantdomainsearch.com/mcp and add it to your MCP settings.

Do not fall back to whois, web search, or any other method.

Available Tools

Three MCP tools are available from the instant-domain-search server:

mcp__instant-domain-search__search_domains — Bulk availability check across chosen TLDs. Start here for any domain query.
mcp__instant-domain-search__generate_domain_variations — Semantic name alternatives when first choice is taken (prefixes, suffixes, brandable modifications — not random strings).
mcp__instant-domain-search__check_domain_availability — Definitive yes/no verification against authoritative registries.

Workflow

Use search_domains with the user's name and desired TLDs
Present results as a table: domain, available (yes/no), notes
If primary choice is taken, automatically call generate_domain_variations and present alternatives
Verify with check_domain_availability before telling the user a domain is definitively available

Output Format

Present ALL results (primary and alternatives) in a single table:

Domain	Available	Notes
enoa.ai	No	Registered
enoa.com	No	Registered
theenoa.com	Yes
goenoa.com	Yes

Rules:

Show domain names only — never show raw URLs or registration links from the API response. Extract the domain name from the result.
One unified table, not separate sections for primary vs alternatives.
Queries go to authoritative registries — no front-running risk. Mention this if the user expresses concern about privacy.

Input

The user provides one or more domain names to check. Accept:

Bare names: example (check across TLDs)
Full domains: example.com (check specific domain + suggest TLD alternatives)
Multiple domains: example.com coolsite.io (check each)
