Overview

AI-generated overview

Searches expired and auction domains from 22 sources with SEO metrics, letting an assistant find aged or dropping domains by filters.

What you can do
  • Search expired and auction domains across 22 sources with filters for source, TLD, quality score, age, backlinks, language, keywords, price and SEO metrics
  • Look up full details for a single domain by ID or name (paid tiers)
  • List available filter options such as sources, TLDs and languages with counts
  • Read platform statistics: total domains, new today, breakdown by source
  • Search a weekly pending-delete inventory with WHOIS status and predicted drop dates (Authority+ tier)
When to use it
Useful when you want to research domain names to acquire — drop-catches, auction listings, aged ccTLDs or domains about to expire — and compare them by SEO authority, backlinks and age without visiting each marketplace.
Requirements
A remote SSE endpoint; the free tier needs no signup or API key. Paid tiers use a separate endpoint with an Authorization Bearer API key from a CatchDoms account. Network access to the CatchDoms service is required.
Before you install
The free tier returns at most 50 results per search with only the first 10 domain names visible and premium metrics hidden, and is rate limited to 3 requests per minute. Paid tiers require a subscription and an API key sent as an Authorization Bearer header. Listings include prices and auction bids; the server does not buy domains, but purchase links lead to third-party marketplaces.

Installation

In SourceWeft

  1. Open CatchDoms — Expired Domains API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.catchdoms%2Fexpired-domains/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

CatchDoms — Expired Domains API & MCP Server

CatchDoms exposes an Expired Domains API and an MCP (Model Context Protocol) server that aggregate 22 sources: 21 auction and marketplace platforms (Dynadot, GoDaddy, DropCatch, SnapNames, Catched, Gname, Namecheap, NameSilo, Sedo, BloomUp, UKDroplists, DomainLore, Rakko, and more) plus an aged ccTLD database of 183,537 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.
