CatchDoms — Expired Domains API

sambel/catchdoms-mcp

Connects Claude to 16 expired domain auction platforms and a 100K+ aged ccTLD database, all with live SEO metrics. You get search_domains with 20+ filters (TLD, age, Trust Flow, Citation Flow, DA, language, price range, GMB detection), plus get_domain for full details and list_filters for available options. Useful when you're hunting drop catches or aged domains and want to query across Dynadot, GoDaddy, DropCatch, Catched, and others without jumping between dashboards. Free tier shows top 10 of 50 results with basic metrics. Pro unlocks full TF/CF data and unlimited results. Authority tier adds the regfee database where aged domains sell at registration price instead of auction.

Readme

CatchDoms Expired Domains API & MCP Server

CatchDoms exposes an Expired Domains API and an MCP (Model Context Protocol) server that aggregate 27 sources: 26 auction and marketplace platforms (Dynadot, GoDaddy, DropCatch, SnapNames, Catched, Gname, Namecheap, NameSilo, Porkbun, Sedo, BloomUp, UKDroplists, DomainLore, Rakko, and the official CZ.NIC, WHC.ca, Internet.ee and Aftermarket.pl registries) plus an aged ccTLD database of 180k+ domains available at registration price. Authority+ adds a weekly pending-delete inventory of domains about to drop. Every domain is enriched with Trust Flow, Citation Flow, Domain Authority, backlinks count, referring domains, and Wayback history.

Use the REST API to integrate expired domain data into your tools, scripts, or pipelines. Use the MCP server to let Claude, Cursor, Windsurf, or any MCP-compatible AI assistant search expired domains conversationally: find drop-catches, check auction prices, and surface high-value aged domains programmatically.
