Overview

AI-generated overview

Lets an assistant verify email addresses as valid, invalid, risky, or unknown using MX, SMTP, catch-all, and disposable checks.

What it does
This remote MCP server exposes email verification through an agent gateway. According to the registry description, it classifies addresses as valid, invalid, risky, or unknown, checking MX records, SMTP responses, catch-all domains, and disposable addresses. It also offers a free agent key, reportedly allowing 25 verifications per day, obtained through a get_api_key tool or a registration endpoint. No individual tool list is published in the manifest.
When to use it
Use it when an assistant needs to clean or screen an email list before outreach, signup, or import, or to check whether a single address is deliverable. It suits workflows where disposable or catch-all addresses matter. It is less useful if you only need syntax validation, which needs no server.
Requirements
A remote streamable HTTP endpoint at the provider's agent gateway; nothing is installed locally. An API key is required, sent in the Authorization header as a Bearer token. A free key with a daily verification limit can be obtained through the get_api_key tool or the registration endpoint. Network access to the provider is required.
Before you install
The Authorization header carries a secret API key; keep it out of logs and shared configuration. Verification sends the email addresses you submit to a third-party service, so consider consent and privacy rules before uploading lists. The free tier is rate-limited, and paid usage or pricing is not described here. No tool list is published, so confirm behavior before relying on it.
