looktwice-mcp

MCP (Model Context Protocol) server for the LookTwice API. Validate emails, EU VAT numbers, IBANs, and domains, and screen products against U.S. CPSC recalls and Product Safety Warnings — directly from Claude Desktop, Cursor, or any MCP client.

npx -y looktwice-mcp

Setup

  1. Create a LookTwice account at looktwice.dev — verified accounts receive 100 free API units each month, no credit card required.
  2. Create an API key in the dashboard.
  3. Add the server to your MCP client configuration:
{
  "mcpServers": {
    "looktwice": {
      "command": "npx",
      "args": ["-y", "looktwice-mcp"],
      "env": {
        "LOOKTWICE_API_KEY": "lt_live_..."
      }
    }
  }
}

Compared with a single-purpose MCP

Most VAT or email MCP servers wrap one upstream. This server keeps the same evidence rules across email, VIES, IBAN, domain, and CPSC: timestamps, official sources, and no mailbox / account / safety claims.

Honest boundaries

  • email_check never claims a mailbox exists (mailbox_status: not_checked).
  • iban_check never claims an account exists or belongs to a person.
  • cpsc_recall_match returns screening candidates with official sources, not safety, legality, or compliance decisions.
