Issue a new invoice for a buyer with line items, payment method and dates.

Számlázz.hu MCP tools: https://cotlet.dev/docs/mcp/szamlazz-hu.md

MCP tool: `szamlazz_hu_write → create_invoice`

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

Issues a numbered invoice, which Számlázz.hu then reports to NAV. Returns the invoice number and the net, VAT and gross totals. The buyer gets the invoice by email only if send_email is true; the default is false. An issued invoice cannot be deleted, only cancelled with cancel_invoice. By default you confirm each call; you can switch that off for this tool.

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.
