`validate_email`

Pack: disify · Endpoint: https://gateway.pipeworx.io/disify/mcp

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

Verify an email address is properly formatted, has valid DNS records, and isn’t disposable or an alias. Returns validation status, a 0-100 confidence score and the signals behind it. Pass your own Disify key as _apiKey — the keyless anonymous quota is shared and usually spent.

Parameters

Name	Type	Required	Description
`email`	string	yes	The email address to validate.
`_apiKey`	string	no	Optional but recommended: your own Disify API key (BYO — Pipeworx does not supply one). Without it the call uses the anonymous tier, whose daily quota is shared across all Pipeworx callers and is usually exhausted. Get one at disify.com.
