1Lookup

Verify phone numbers, emails and IPs, and check remaining plan credits. 1Lookup is a data verification platform. Its hosted MCP server lets an AI agent validate a phone number, verify an email address, or look up an IP mid-workflow, without leaving the conversation. Connect with one URL over OAuth 2.1, with no API key to paste into a config file. **Tools** - `validate_phone` : line type, carrier, DNC status and a fraud risk score - `verify_email` : deliverability, plus disposable and role-based flags - `ip_lookup` : geolocation with proxy, VPN, Tor and datacenter detection - `bulk_verify` : up to 50 phones, emails or IPs in one call - `get_account` : plan and remaining credits, free, spends no credits **Pricing** One credit per lookup, shared with the 1Lookup REST API. `get_account` is free. Requires a paid plan, and every plan starts with a 7-day free trial. [Documentation](https://www.1lookup.io/products/mcp)
