Validate\nemails, EU VAT numbers, IBANs, and domains, and screen products against U.S. CPSC recalls and\nProduct Safety Warnings — directly from Claude Desktop, Cursor, or any MCP client.\n\n```bash\nnpx -y looktwice-mcp\n```\n\n## Setup\n\n1. Create a LookTwice account at [looktwice.dev](https://looktwice.dev/sign-up) — verified\n   accounts receive 100 free API units each month, no credit card required.\n2. Create an API key in the [dashboard](https://looktwice.dev/dashboard).\n3. Add the server to your MCP client configuration:\n\n```json\n{\n  \"mcpServers\": {\n    \"looktwice\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"looktwice-mcp\"],\n      \"env\": {\n        \"LOOKTWICE_API_KEY\": \"lt_live_...\"\n      }\n    }\n  }\n}\n```\n\n## Tools\n\n| Tool                | What it does                                                                | Cost       |\n| ------------------- | --------------------------------------------------------------------------- | ---------- |\n| `email_check`       | Syntax, MX, disposable, role, free-provider signals (no mailbox probing)    | 2 units    |\n| `vat_check`         | Live EU VIES validation with returned business data and request evidence    | 1 unit     |\n| `iban_check`        | Country structure, length, and MOD-97 checksum (no account-existence claim) | 1 unit     |\n| `domain_check`      | DNS, MX, TLS, and RDAP state for a registrable domain                       | Free quota |\n| `cpsc_recall_match` | Evidence-backed candidate matching against CPSC recalls and warnings        | 3 units    |\n| `credits_balance`   | Current workspace credit balance                                            | Free       |\n\n## Compared with a single-purpose MCP\n\nMost 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.\n\n## Honest boundaries\n\n- `email_check` never claims a mailbox exists (`mailbox_status: not_checked`).\n- `iban_check` never claims an account exists or belongs to a person.\n- `cpsc_recall_match` returns screening candidates with official sources, not safety, legality,\n  or compliance decisions.\n\n## Environment variables\n\n| Variable             | Required | Default                     |\n| -------------------- | -------- | --------------------------- |\n| `LOOKTWICE_API_KEY`  | Yes      | —                           |\n| `LOOKTWICE_BASE_URL` | No       | `https://api.looktwice.dev` |\n\n## License\n\nMIT\n",
