Expired domains skill

Find Expired Domains

This skill turns your agent into an expired-domain prospector. It connects to CatchDoms, a platform that aggregates expired, dropping, and auction domains from 19+ registrars and enriches each one with SEO metrics, then lets you search and qualify them in natural language.

When to use this skill

Use it whenever the user wants to:

• Find expired / aged domains for SEO (money sites, niche sites, affiliate, PBN)
• Drop-catch a deleted domain or back-order an expiring one
• Evaluate a specific domain's authority and backlink profile before bidding
• Compare auction listings (current bid, end time, platform) across registrars
• Find domains in a niche (by keyword, TTF topic category, or language)
• Find aged domains in a specific TLD (.com, .fr, .de, .co.uk, …)

How it works — connect the MCP server first

CatchDoms exposes its data over the Model Context Protocol (MCP). There are two endpoints. Start with the free one; it needs no account.

Free tier (no auth — recommended starting point)

• URL: https://catchdoms.com/mcp/catchdoms/free
• Transport: HTTP (streamable)
• Returns the top 50 domains per search. The first 10 domain names are shown in full; the rest are masked. Premium metrics (Trust Flow, Citation Flow, TTF topic, GMB) are hidden behind a free signup.
• Rate limit: 3 requests/min.

Add it to Claude Code:

claude mcp add --transport http catchdoms https://catchdoms.com/mcp/catchdoms/free

Or in ~/.claude.json / claude_desktop_config.json:

{
  "mcpServers": {
    "catchdoms": {
      "type": "http",
      "url": "https://catchdoms.com/mcp/catchdoms/free"
    }
  }
}

For Claude Desktop (needs Node for the remote bridge):

{
  "mcpServers": {
    "catchdoms": {
      "command": "npx",
      "args": ["mcp-remote", "https://catchdoms.com/mcp/catchdoms/free"]
    }
  }
}

Pro tier (full access — Bearer token)

For all domain names, full metrics (TF/CF, GMB, TTF topic), 80K+ aged registrable ccTLD domains, and unlimited results, use the authenticated endpoint with a CatchDoms Pro API token:

• URL: https://catchdoms.com/mcp/catchdoms
• Header: Authorization: Bearer <YOUR_CATCHDOMS_API_KEY>
• Get a token at https://catchdoms.com/pricing

{
  "mcpServers": {
    "catchdoms": {
      "type": "http",
      "url": "https://catchdoms.com/mcp/catchdoms",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" }
    }
  }
}

If the MCP server is connected, prefer its tools over scraping or guessing. If it is not connected, tell the user to add it (commands above) before you can return live data — do not invent domain metrics.

Tools available on the server

Tool	What it does
search_domains	Search/filter domains. Returns them ranked by quality and auction interest.
get_domain	Get full details for one domain by id or name (Pro endpoint).
list_filters	List available sources, TLDs, and languages with counts.
get_stats	Platform stats: total domains, new today, breakdown by source.

search_domains filters

Pass only the filters that matter; everything is optional and AND-combined.

• source — one of: dynadot, catched, dropcatch, godaddy, gname, snapnames, ukdroplists, subreg, webexpire, parkio, bloomup, seodomains, nameshift, namesilo, nicsell, gnews-domains, backorders-domains, domainlore, rakkodomain, namepros, regfree (regfree = deleted/registrable ccTLD domains, Pro only).
• tld — e.g. .com or .fr; comma-separated for several (.fr,.de,.it).
• score_min — quality score 0-100. Use 30+ decent, 50+ good, 70+ excellent.
• age_min — minimum age in years (first Wayback snapshot).
• type — auction, closeout, or backorder.
• has_bids — true to keep only domains with live bids (market interest).
• has_backlinks — true to require referring domains (SEO value).
• da_min — minimum Domain Authority (0-100).
• rd_min — minimum referring domains.
• tf_min / cf_min — minimum Trust Flow / Citation Flow (Pro tier).
• has_edu_gov — true to require .edu/.gov referring domains.
• categories — comma-separated TTF topic categories (Business,Health).
• language — detected content language code (EN, FR, DE, ES, …).
• contains — keyword in the domain name; comma list = OR (shop,store).
• price_min / price_max — bid/price bounds in USD.
• snapshots_min — minimum Wayback snapshots.
• techs — historical tech stack labels, OR semantic (WordPress, Shopify,Stripe).
• limit — 1-100 (free tier capped at 50).

How to qualify a domain (the part that matters)

Raw metrics lie. Walk the user through real quality, not just a high DA:

1. Backlink quality over quantity. 50 real editorial referring domains beat 5,000 spam links. Check referring_domains, da_min, and whether links are topical. has_edu_gov=true is a strong trust signal.
2. Trust Flow vs Citation Flow. A healthy ratio (TF/CF) above ~0.5 means the link profile is trusted, not just large. Low TF with high CF = link spam.
3. Age and history. age_min + snapshots_min confirm the domain actually had a real site, not a parked shell. Cross-check on the Wayback Machine.
4. Topical match. Use categories (TTF topic) and language so the domain's history matches the user's project niche — relevance compounds authority.
5. Clean name. Prefer no hyphens/numbers (already filtered out at import on most sources), pronounceable, brandable for a money site.
6. Auction economics. For auctions, weigh current bid (price_min/max, has_bids) against the value of the link profile and the auction end time.
7. Spam check. Be wary of gambling/pharma/adult keywords, foreign-language spam history, and link networks. A high score with a spammy niche is a trap.

Always recommend the user verify backlinks independently (Ahrefs/Majestic) and check the Wayback Machine before spending real money.

Example interactions

"Find me aged French domains with good backlinks under $100."

search_domains(tld=".fr", age_min=10, has_backlinks=true, price_max=100, score_min=50)

"Any WordPress sites in the health niche with edu/gov links?"

search_domains(techs="WordPress", categories="Health", has_edu_gov=true, score_min=50)

"What's currently up for auction on DropCatch with bids and DA 30+?"

search_domains(source="dropcatch", type="auction", has_bids=true, da_min=30)

"Show me the strongest .com closeouts right now."

search_domains(tld=".com", type="closeout", score_min=70, limit=50)

After returning results, summarize the top 3-5 picks with their key metrics and a one-line rationale, then point the user to the listing on CatchDoms to bid/buy.

Notes & limits

• Free tier: top 50 results, first 10 names visible, premium metrics masked, 3 req/min. Sign up free at https://catchdoms.com/register to unlock more.
• regfree (deleted registrable ccTLD domains) requires a Pro/Authority plan.
• Domains with hyphens and numbers are excluded at import on most sources.
• This skill reads live data only; it does not place bids or buy domains. Send the user to the registrar via the listing link to complete a purchase.
