`email_verifier`

Pack: hunter · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/email_verifier for the schema, then POST the same URL with its arguments for the data.

Verify an email address with Hunter.io email verification. Checks deliverability, MX records, SMTP, and whether the address is disposable or webmail. Returns a status, result, and confidence score. Example: email_verifier({ email: “[email protected]” })

Parameters

Name	Type	Required	Description
`email`	string	yes	Email address to verify, e.g. “[email protected]”
`_apiKey`	string	no	Optional — your own Hunter.io API key for higher limits; omit to use the shared Pipeworx key.
