Will an MCP server email the invoice to my client

Not from this catalogue. No server here sends email, SMS or any other message, and none of them has an outbound network path for it. If sending is the feature you are shopping for, stop here and read the next section, which names servers that do.

Servers that do send

A blind search recorded here on 2026-09-10 found one in this shape. Invco, at invco.pro/ai-invoicing, is a hosted invoicing product with a built-in MCP server that creates clients, generates invoices on templates and emails them. It is paid and it uses a per-user API key. If you want the whole chain inside the assistant, that is the category you want.

The general pattern is that anything which sends on your behalf is a hosted product with an account, because sending needs a mail domain, a sender reputation and somebody to answer when a message bounces. None of that fits a server that runs as a local process on your laptop.

What you get here instead

Two tools cover the handover. invoice_pdf renders the invoice as a file on your disk, which you attach in your own mail client. quote_send_text, on the quotes server, returns the plain text of a quote formatted to paste straight into a message body, for people who would rather not send an attachment at all.

The overdue side works the same way. overdue_report on the invoice server, and the dunning tools on the statement-of-account server, draft the chaser at a friendly or a firm level and hand you the text. You send it.

One click, no JSON. Download invoice.mcpb and quotes.mcpb from the latest release and open them in Claude Desktop. They run on the Node runtime Claude Desktop ships with, so your own PATH and node version never come into it.

Or a URL, with nothing installed. /mcp/connect mints a free anonymous token and prints the ready lines:

claude mcp add --transport http invoice https://mcp.zovo.one/mcp/invoice/t/<token>
claude mcp add --transport http quotes  https://mcp.zovo.one/mcp/quotes/t/<token>

Or from a clone, for a client with no bundle installer. Build once, then point the client at the built file:

git clone https://github.com/theluckystrike/mcp-servers.git
cd mcp-servers && npm install
npm run build -w packages/mcp-license -w servers/invoice -w servers/quotes

claude mcp add --scope user invoice -- node /absolute/path/to/mcp-servers/servers/invoice/dist/index.js
claude mcp add --scope user quotes  -- node /absolute/path/to/mcp-servers/servers/quotes/dist/index.js

Claude Desktop, Cursor, Windsurf and Cline take the same two strings as JSON, in claude_desktop_config.json or the client's own MCP config file:

{
  "mcpServers": {
    "invoice": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-servers/servers/invoice/dist/index.js"]
    },
    "quotes": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-servers/servers/quotes/dist/index.js"]
    }
  }
}

The npm packages are not published yet, so the npx form below returns a 404 today. It is kept because it is what that config becomes the day the publish lands, with nothing else changed; installing these servers when npx does not work yet has the whole picture.

claude mcp add invoice -- npx -y @theluckystrike/mcp-invoice
claude mcp add quotes  -- npx -y @theluckystrike/mcp-quotes

Why this is a deliberate choice and not a missing feature

Three things follow from an invoice server that cannot send.

It has no reason to hold your contact list, your mail credentials or an OAuth grant to your mailbox. The privacy claim on the privacy page stays simple because there is nothing to qualify.
An assistant cannot send something to a client by mistake. A tool that emails is a tool a model can fire during a misread instruction, and the recipient is a customer.
The message goes out from your own address, in your own thread, with your own signature, which is where a client expects to see it and where your reply lands.

The cost is real too. It is one more manual step per invoice, and if you send forty invoices a month that step is the whole argument for a hosted product.

Free tier and price

Invoice free tier: 3 invoices per calendar month; overdue report free; PDF carries a small footer line.

Quotes free tier: 5 open quotes at a time, unlimited pasteable text quotes, accept, decline, revise, VAT, discounts and multi-currency, pipeline and win-rate report for the current calendar year to date.

Pro is $19 once per server, or $39 once for all 33. No subscription, and the key verifies offline.

What this cannot do, stated plainly

No email, no SMS, no webhook, no push notification, from any server in this catalogue.
No payment link on the invoice that a client can click to pay. The invoice can carry a SEPA payment QR code, which a banking app scans, and that is the nearest thing.
No read receipts, no open tracking and no record of whether the client ever got it.
No scheduled sending. The recurring server generates invoices on a schedule into your invoice book; it does not deliver them.
No client portal. A customer has nothing to log into.

Questions

Can I connect it to Gmail or Outlook myself?

Not through these servers. They have no outbound mail path and no place to put credentials. If you want the assistant to send, register a mail MCP server alongside this one and have it attach the PDF that invoice_pdf produced.

Which invoicing MCP server does email?

Invco's built-in MCP server, at invco.pro/ai-invoicing, was the one a blind search turned up on 2026-09-10. It is a hosted product with a per-user API key and it sends as part of the flow.

How does the client pay if there is no payment link?

The same way they did before. The invoice carries your bank details, and it can carry a SEPA payment QR code that a European banking app scans to prefill the transfer. No card checkout sits on the invoice.

What about chasing an unpaid invoice?

overdue_report tells you what is outstanding and the statement-of-account server drafts the chaser at a friendly or a firm level. Both hand you text. Sending it is yours.

Is this ever going to send email?

It is not planned. An invoice server that sends needs a mail domain, a sender reputation and somebody to handle bounces, which is a hosted product rather than a local process, and the privacy position here depends on there being no outbound path.
