How to send certified mail without going to the post office

You can send certified mail from your couch. Ask your AI assistant to mail the letter certified with No Errands. It checks the address, quotes the price ($11.99 for one page), and after your yes the letter is printed and sent certified by our mail partner. No forms to fill in at a counter.

How to do it with No Errands

Connect No Errands once. Add No Errands to Claude, ChatGPT or another MCP client with the address https://api.noerrands.com/mcp and sign in with your email. The steps for each assistant are below. You do this once for every errand.
Add credits if you need them. A new account starts at $0.00. Ask your assistant to add credits and it gives you a checkout link. You pay in your own browser, never in the chat.
Give it the letter and the addresses. Tell the assistant who the letter is for, their US address, your return address, and what to say. It can write the letter with you, use text you paste, or mail a PDF from a link.
Check the address and the price. The assistant checks the address for free and gets the exact price before anything is printed.
Approve it. It shows you the recipient, a summary of the letter and the price, then waits for your yes. Nothing is mailed until you say so.
It is printed and mailed. The letter is printed, put in an envelope, stamped and handed to USPS. Ask the assistant for the status any time.

What to type

Once No Errands is connected, you can ask like this:

I need to send my 30-day notice certified. Mail it to my landlord at 400 Pine St, Chicago IL 60614 and show me the final letter first.

The assistant checks first, shows you what it is about to do and the price, and waits for your yes.

Connect No Errands to your AI assistant

You do this once. One connection covers every errand, and the address is the same everywhere: https://api.noerrands.com/mcp.

Claude: open Claude's connector settings and choose Add custom connector. Name it No Errands, paste https://api.noerrands.com/mcp, click Add, then Connect.
ChatGPT: go to Settings, then Apps & Connectors, then Advanced, and turn on Developer mode. Create a connector with the address https://api.noerrands.com/mcp and authentication set to OAuth.
Claude Code: run claude mcp add --transport http errands https://api.noerrands.com/mcp, then type /mcp and sign in.
Cursor, Meta Muse and other MCP clients: add https://api.noerrands.com/mcp as a streamable HTTP server and sign in, or get an API key and send it as a bearer token.

Signing in asks for your email and a 6-digit code we email you. Then choose Allow read and spend credits, or Allow read-only if you only want quotes and status. A new account starts at $0.00: ask your assistant to add credits and it gives you a checkout link to pay in your own browser.

Questions people ask

Can I track it?

Ask your assistant for the status of the letter at any time. It reports where it is, from processing to delivered.

Can I cancel a certified letter?

Only before you approve it. Once it is handed to the print partner it is on its way.

Can the assistant mail a letter without asking me?

No. It must check the address, get a price, show you the recipient, the content and the price, and get your explicit yes before every letter. A read-only connection cannot send at all.

Can I mail a letter outside the US?

Not yet. United States addresses only.

How do I pay?

With prepaid credits. You can buy $2.49 for a single letter, or $10.00 for $12.50 of credit (one free letter), $25.00 for $32.50 of credit (three free letters) and $50.00 for $67.50 of credit (seven free letters); every pack credits more than it costs, and credits never expire. Your assistant gives you a checkout link and you pay in your own browser.
