MCP server
Signup checks your AI agent can call.
Connect Veqen to Claude, ChatGPT, Cursor or any MCP client. Your agent can check an email, IP, phone number, domain or whole signup before it acts, and tell you why.
Two ways in.
Sign in with OAuth (Claude, ChatGPT)
Add a custom connector with this URL. You'll be asked to sign in and approve. No key to copy.
Or send your API key (Claude Code, Cursor, scripts)
Use the header form shown here. The key works exactly like it does for the REST API.

}What the agent gets.
| Tool | Use it when | Credits |
|---|---|---|
check_email_address | Someone gives an email and you need to know if it's real, throwaway or a typo. | 1 (+5 mailbox) |
check_ip_address | You have a visitor's IP and need location, network owner, or datacenter/VPN/Tor status. | 1 |
check_phone_number | You need to validate or format a number, or know if it's mobile, VoIP or toll-free. | 1 |
check_domain_name | You need to know if a company domain exists, receives mail and how old it is. | 1 |
check_signup_risk | You're deciding whether to accept a signup or lead and have several details. | 3 |
get_balance | You want to know how many credits are left. | 0 |
Checks spend credits; balance lookups are free. Agents can't change your settings or see your keys. If you enable auto top-up, credit use can trigger a payment. See the MCP docs.

Add a custom connector with the URL /mcp on this site and sign in when asked. Claude Code and other header-based clients can send your API key as a Bearer token instead.
What can the agent do with it?
Check emails, IPs, phone numbers, domains and whole signups, and read the account balance. It cannot change your account, buy credits or see your keys.
Who pays for the checks the agent runs?
They spend the connected account's credits, at the same price as API calls.
