Overview

Description from the maker (original English)

Verify email addresses with Emailable one by one or in batches, and read credits and batch results.

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.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Chat & email

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.
  • Can do 4 things (tools) emailable_get_account, emailable_verify_email, emailable_create_batch, emailable_get_batch
  • The registry lists no key to fill in.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • emailable_create_batch

    SPENDS CREDITS: starts a bulk verification of up to 5000 email addresses. Emailable takes 1 credit per email when the batch is created, and if the account has too few credits it may charge the account's saved card to buy more. A test_ API key spends nothing. The batch cannot be c

  • emailable_get_batch

    Status and results of a batch made with emailable_create_batch: message, progress (processed/total), reason_counts and total_counts (deliverable, undeliverable, risky, unknown). Batches of up to 1,000 emails also return the results inline in `emails` (30 days). They come in pages

Common questions

Is Emailable MCP by usefulapi 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?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.22.3) reached the registry yesterday.

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

Emailable MCP by usefulapi

Use Emailable from Claude, Cursor, or any MCP client — check your account and credits, verify single email addresses, run batch verifications (up to 5,000 addresses, with confirmation) and read batch results page by page. Every verification spends credits from your own Emailable account. Hosted, no local install: connect with your own Emailable credentials.

Live endpoint: https://emailable.usefulapi.io/mcp · Homepage: https://usefulapi.io/emailable

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://emailable.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http emailable https://emailable.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{

"mcpServers": { "emailable": { "url": "https://emailable.usefulapi.io/mcp" } } }

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Emailable credentials.
