Create the next reminder for an overdue invoice and email it to the customer.

sevdesk MCP tools: https://cotlet.dev/docs/mcp/sevdesk.md

MCP tool: `sevdesk_write → create_payment_reminder`

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

Creates the next reminder for an invoice and sends it by email. The first one is a Zahlungserinnerung; later ones are Mahnungen, which sevdesk offers from the Buchhaltung plan and bases on an invoice that already got a reminder. The text is prefilled by sevdesk unless you pass message, and the deadline comes from your Mahnfrist setting. 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. |
| `message` | string | no | Text of the reminder. Default: the sevdesk standard text. |

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.
