Send a sales invoice by email to one or more addresses.

Alegra MCP tools: https://cotlet.dev/docs/mcp/alegra.md

MCP tool: `alegra_write → email_invoice`

Access: write. Confirm: waits for the user's OK before it runs.

Sends the invoice through Alegra's invoice email, so the client receives the message of the template "Correo de envío de facturas de venta". Only the subject can be set per call; without one Alegra uses a default subject. The invoice goes out as the original unless as_copy is true. Fails with a not-found error when the invoice does not exist. Calling it twice sends two emails. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `invoice_id` | string | yes | Invoice ID from list_invoices. |
| `emails` | array | yes | Recipient addresses, even for one recipient. |
| `subject` | string | no | Email subject. Default: the subject Alegra sets. |
| `send_copy_to_me` | boolean | no | true also sends a copy to your own address. Default: false. |
| `as_copy` | boolean | no | true sends the invoice marked as a copy. Default: false, the original. |

## For AI agents: sign your user up

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.

One call creates the account and sends the access request; we email the user when access is granted.
