Cursor

This guide details how to add Instant Domain Search's MCP to the Cursor IDE.

Requirements

The Instant Domain Search MCP is free to use. You'll need Cursor installed on your machine with MCP support enabled.

How It Works

Domain status comes from our search index, rebuilt daily from registry zone files and DNS observations. Checks do not make live registry queries. Uncovered extensions can have unknown status. Confirm availability with the registrar before purchase.

  • search_domains — Checks one name across many extensions. Takes a name without an extension and returns the registration status for each extension you choose, or for the popular ones by default, from an index rebuilt daily.
  • generate_domain_variations — Alternatives when your first choice is taken. Adds common prefixes and suffixes to a name and returns the .com for each, sorted by how common the added word is or by how close it is in meaning to the original.
  • check_domain_availability — Check registration status for up to 50 full domain names from the daily index. Uncovered extensions have unknown status. Results include registration links; confirm availability with the registrar before purchase.
  • search_trademarks — Search indexed USPTO trademark records with exact, prefix, fuzzy, or phonetic matches. Filter by status, class, or owner, and return up to 100 matches. Results include the snapshot freshness.
  • get_trademark_details — Look up a trademark by its eight-digit USPTO serial number. Get its status, dates, owners, classes, goods and services, filing flags, and snapshot freshness.
  • submit_feedback — Let your agent report tool issues and useful observations. Feedback must exclude search queries, domain names, results, and private details. The agent should not ask you for feedback.

Setup Guide

Option 1: Quick Install (Recommended)

Simply click the following link:

Option 2: Manual Configuration

If you prefer to configure manually, add this to your mcp.json file:

  "mcpServers": {
    "Instant Domain Search": {
      "url": "https://mcp.instantdomainsearch.com/mcp"
    }
  }
}

To access your mcp.json file:

Installing the Instant Domain Search MCP in Cursor

Using the MCP in Cursor

Once installed, you can use the Instant Domain Search MCP directly in your chat:

Can you help me find a domain available for slowdomains? That's my startup name

The MCP will automatically search for available domains and provide intelligent suggestions.

Using the Instant Domain Search MCP inside Cursor

Example Use Cases

  • Project naming: "I need a domain for my new SaaS project"
  • Client work: "Find available domains for my client's restaurant"
  • Open source projects: "Check if projectname.dev is available"
  • Bulk checks: "Check these 10 domain names for availability"

Privacy & Security

Domain checks use our own index instead of a live query to a retail registrar. No account or API key is required for the MCP server.

Troubleshooting

MCP not appearing in Cursor Ensure you've restarted Cursor after adding the configuration.

Next Steps

Start using the MCP by asking Cursor to help you find domains. Try prompts like:

  • "Find available domains for my startup"
  • "Check if this list of domains is available"
  • "Generate creative variations for my brand name"

The Instant Domain Search MCP brings domain index results and USPTO trademark records into your development workflow.
