Let Claude or another MCP-compatible AI check your balance, look up orders, and send letters on your behalf
Send a USPS Certified Mail letter to any US address from ChatGPT, Claude or Grok.

Nothing is printed, mailed or charged without that approval. $16.17 with the electronic return receipt, $13.18 without. No subscription, and no account needed to see a price.
