About x402 Email Verifier

A remote MCP server for checking email syntax and domain-level mail readiness. It checks MX records and risk indicators, then returns a score and verdict; each `email_verify` call costs $0.001 USDC via x402.

Key features

  1. 01Check email syntax
  2. 02Look up MX records
  3. 03Flag disposable and role addresses
  4. 04Identify free-mail providers
  5. 05Return a score and verdict

Use cases

  1. 01Screen an address before sending email
  2. 02Assess domain-level mail readiness
  3. 03Flag risky addresses before storing them

MCP support

Exposes `email_verify` and a free `health` tool over Streamable HTTP at `/mcp`. Verification calls require x402 payment; the server does not probe whether an individual mailbox exists.

Configuration

Remote servers need no local install. Pick your client, then copy the config or install in one click.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
