Overview

Description from the maker (original English)

Real-time email verification and deliverability diagnostics (MX, SPF, DKIM, DMARC).

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Works in Claude on the web, desktop and mobile:

  1. Open Settings → Connectors
  2. Press Add custom connector
  3. Paste the address below and press Add
  4. If it asks you to sign in, sign in with the maker

      ]
    }
  }
}

Run this in your terminal

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

The server asks you to sign in before it lists its tools.

Common questions

Is VerifyAnyEmail safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.3) reached the registry 7 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Vexa, emailmd, MCP WhatsApp Cloud

VerifyAnyEmail MCP Server

Official Model Context Protocol server for VerifyAnyEmail — give any AI agent real-time email verification and deliverability diagnostics.

Works with Claude Desktop, Claude Code, Cursor, Windsurf, ChatGPT (MCP connectors), and any other MCP client.

What it does

ToolDescriptionCredits
verify_emailVerify one address — verdict (deliverable/undeliverable/risky/unknown), 0–100 score, safeToSend, and signals (catch-all, disposable, role-based, typo).1 per call
verify_batchSubmit many addresses for async bulk verification; returns a batchId.1 per address
get_batch_statusPoll a batch's progress and per-status counts.free
get_batch_resultsFetch a paginated page of batch results.free
check_mxDomain MX records / can it receive mail.free
check_spfSPF record + misconfiguration flags.free
check_dmarcDMARC policy and alignment.free
check_dkimDKIM record for a selector.free
check_domain_healthCombined MX/SPF/DKIM/DMARC health grade with findings.free

The diagnostics are free (no verification credits). Verification spends credits — except test addresses at test.verifyany.email (deliverable@, undeliverable@, risky@, unknown@), which return canned results and cost 0 credits, perfect for trying it out.

Setup

You need a VerifyAnyEmail API key (vae_…) — create one in the dashboard → API Keys.

The server is distributed on npm and runs with npx (no install needed).

Claude Desktop

Edit claude_desktop_config.json (Settings → Developer → Edit Config):

{

"mcpServers": { "verifyanyemail": { "command": "npx", "args": ["-y", "verifyanyemail-mcp"], "env": { "VERIFYANYEMAIL_API_KEY": "vae_your_key_here" } } } }

Restart Claude Desktop. You'll see the VerifyAnyEmail tools available.

Claude Code
claude mcp add verifyanyemail -e VERIFYANYEMAIL_API_KEY=vae_your_key_here -- npx -y verifyanyemail-mcp
Cursor

Add to ~/.cursor/mcp.json (or a project .cursor/mcp.json):

{

"mcpServers": { "verifyanyemail": { "command": "npx", "args": ["-y", "verifyanyemail-mcp"], "env": { "VERIFYANYEMAIL_API_KEY": "vae_your_key_here" } } } }

Any other MCP client

Run the binary over stdio with the API key in the environment:

VERIFYANYEMAIL_API_KEY=vae_your_key_here npx -y verifyanyemail-mcp

Configuration

Env varRequiredDefaultPurpose
VERIFYANYEMAIL_API_KEY✅—Your vae_… API key.
VERIFYANYEMAIL_BASE_URL—https://api.verifyany.emailOverride the API base URL.
VERIFYANYEMAIL_TIMEOUT_MS—30000Per-request timeout in milliseconds.

Example prompts

  • "Is jane.doe@acme.com a real, safe-to-send address?"
  • "Verify these 500 signups and tell me which are risky." (uses verify_batch)
  • "Check the email deliverability health of example.com."
  • "Does example.com have a valid SPF and DMARC setup?"

Security

  • Your API key is read only from the server's environment and sent only to the VerifyAnyEmail API over HTTPS. It is never logged (logs go to stderr; the stdout stream is reserved for the MCP protocol).
  • Keep the key server-side — treat the MCP config file like any other secret.
