SendLettersOnline.co.uk MCP Server
Send real postal letters from your AI assistant, printed and posted via Royal Mail.
About
SendLettersOnline.co.uk lets AI assistants send real physical letters to UK and international addresses. Your assistant writes the letter, gets an exact price quote, and places the order once you approve it. We print it and post it via Royal Mail, with options from second class to Special Delivery and international tracked.
Tools: get_balance (check your prepaid balance), list_orders (recent letters), get_order (status of one letter), preview_letter_price (quote without charging) and create_letter_order (places a paid order only when called with confirmed: true and the exact quoted total, so nothing is charged by accident).
Remote server over Streamable HTTP, authenticated with OAuth or a bearer API key. Built for individuals, small businesses and expats who need to send letters to HMRC, DVLA, councils, MPs, landlords, family and more without a printer or a trip to the Post Office.
