Overview

AI-generated overview

A remote MCP server that lets an assistant validate up to 10 email addresses at a time, returning a verdict, score and deliverability signals.

What you can do
Validate email addresses in batches of up to 10, checking syntax and whether the domain exists and has mail servers (MX). Identify the mail provider and flag disposable, role-account (info@, sales@) and free-provider addresses. Detect likely typos and suggest a fix, and report domain age plus SPF and DMARC status. Return a verdict (deliverable_likely, risky, undeliverable or invalid) with a score.
When to use it
Useful when cleaning a contact or signup list, screening leads before outreach, or checking an address before sending important mail. Best for quick batch checks where a verdict and risk flags are enough.
Requirements
A remote endpoint; the assistant connects to the hosted service over streamable HTTP. No packages, environment variables or headers are declared, and no authentication is declared. Network access to the endpoint is required.
Before you install
Email addresses submitted for validation are sent to a third-party hosted service, so avoid sending sensitive or personal addresses without checking its data handling. Results are likelihood estimates, not proof an address works. No authentication is declared, so anyone with the endpoint can call it.

Installation

In SourceWeft

  1. Open Mailvett: Email Validation API for AI Agents in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.shawmena-dotcom%2Femail-validate/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
