CatchDoms — Expired Domains API MCP server

CatchDoms — Expired Domains API & MCP Server

CatchDoms exposes an Expired Domains API and an MCP (Model Context Protocol) server that aggregate expired domains from 16 auction platforms (Dynadot, GoDaddy, DropCatch, SnapNames, Catched, Gname, BloomUp, UKBackorder, DomainLore, and 7 more) plus 100,000+ aged ccTLD domains available at registration price. 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.
