What the assistant can do

Look up (no extra permission)

• list_destinations — destinations, products and prices

• get_quote — price of one letter

• registered_mail_requirements — whether a letter type must go by registered mail in DE, FR, BE, ES, CH, NL, GB or US

These three tools are also available, without a token, at /mcp/public.

Send (letters:write)

• upload_document — store a PDF and check that it can be printed

• create_order — prepare the letter and show the price; nothing is charged

• confirm_and_pay — after you approve, pay from credit or return a checkout link

• withdraw_order — cancel and refund a paid letter that has not yet been handed to the post

Track (letters:read)

• get_order_status — status, price and tracking number

• get_proof_certificate — proof facts of a posted letter

The send and track tools are documented at https://sendregistered.com/developers/mcp. They are not returned by /mcp/public.

How you stay in control

The assistant shows the recipient, product, pages and price first. Nothing is posted until you approve. A connection can be limited to read access, or given a daily and monthly spend limit from prepaid credit. PDFs are stored encrypted in the EU and used only to print the letter.

Same prices as the website. Privacy policy: https://sendregistered.com/privacy. Terms: https://sendregistered.com/terms.
