# Mailvett by CyberMax

> Free email validation API and MCP server: syntax, MX, disposable, role, free-provider and typo checks with a verdict, reasons and a 0-100 score. No SMTP probing.

Paste addresses and get a clear verdict for each: syntax, domain and mail server (MX), mail provider, disposable, role (info@, sales@), free provider and likely typos (gmial.com → gmail.com), plus domain age, SPF and DMARC.

## API (free, no key, CORS enabled)
- [/api/validate](https://mailvett.cybermax-tools.workers.dev/api/validate?email=jane.doe%40gmial.com,info%40stripe.com): Validate up to 10 email addresses
- GET for simple calls, POST a JSON body for lists. Same field names as the bulk version's dataset records.
- OpenAPI 3.1: https://mailvett.cybermax-tools.workers.dev/openapi.json

## MCP (remote, streamable HTTP, no auth)
- Endpoint: https://mailvett.cybermax-tools.workers.dev/mcp
- `validate_emails`: Check up to 10 email addresses: syntax, whether the domain exists and has mail servers (MX), mail provider, disposable, role account (info@, sales@), free provider, likely typo with a suggested fix, domain age, SPF and DMARC. Returns verdict (deliverable_likely/risky/undeliverable/invalid), score 0-100 and reason codes per address. Does not verify that the mailbox itself exists.

## Limits
- 20 calls per minute per IP address.
- Up to 10 emails per call.
- Domain age and parked-site checks run in full for up to 5 different domains per call.
- Mailboxes are never probed (no SMTP), so the top score is 90.
- Free, no key.
