Overview

AI-generated overview

A remote MCP endpoint that lets an assistant validate email addresses, checking MX records, provider, disposable/role/free flags, typos and an overall verdict.

What you can do
Validate email addresses and return an overall verdict on whether they look deliverable or usable. Check domain mail setup through MX records and identify the email provider. Flag disposable, role-based and free-mailbox addresses. Suggest corrections for likely typos in the address.
When to use it
Useful when an assistant needs to check email addresses before sign-up, outreach or list cleaning, or to spot disposable, role or mistyped addresses in user-supplied data.
Requirements
A remote streamable HTTP endpoint; no local package or runtime is needed. An optional paid-plan API key is supplied in the x-api-key header; leaving it out uses the free daily tier.
Before you install
The x-api-key header carries a paid-plan credential, so keep it out of logs and shared transcripts. Validation results are heuristic and should not be treated as proof an address is deliverable. Addresses submitted are sent to a third-party service.

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/dev.workers.cybermax-tools.cybermax%2Fmailvett/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
