How to use Meta Muse for real-world errands

Meta Muse writes the letter. It cannot put it in a mailbox. These guides cover everything on the other side of that gap: posting paper, sending faxes, booking appointments, getting a table, shipping a package, printing photos, mailing greeting cards, getting documents signed, and the plain-language background on keys, prices and custom connectors.

Using Claude, ChatGPT, Claude Code or Cursor instead? See the guides for any AI assistant: one connector address, an email sign-in, and step-by-step answers for faxing, mailing, shipping, printing and signing.

Every guide uses the same one-paste setup, so if you have done it once you can skip straight to the asking. United States only.

The one-paste setup

Get a key at https://noerrands.com/get-key, then copy the whole block and paste it into Muse as one message. You do this once and it covers mail, fax, bookings, tables, shipping, prints, cards and signatures.

Build a custom connector for No Errands. One API key covers eight services:
printed mail (letters and postcards), fax, appointment booking, asking a
restaurant for a table, shipping labels, printing and posting photos,
mailing greeting cards, and getting documents signed.

1. Read these eight connector briefs and follow them exactly:
   https://noerrands.com/connectors/muse.md
   https://noerrands.com/connectors/fax/muse.md
   https://noerrands.com/connectors/booking/muse.md
   https://noerrands.com/connectors/tables/muse.md
   https://noerrands.com/connectors/ship/muse.md
   https://noerrands.com/connectors/prints/muse.md
   https://noerrands.com/connectors/cards/muse.md
   https://noerrands.com/connectors/sign/muse.md

2. Store my API key in the Secure Credentials Store as NOERRANDS_API_KEY.
   The same key works for all eight. Never print, log, echo, or repeat
   it, not even partially.
   Send it as the header: Authorization: Bearer <NOERRANDS_API_KEY>

3. Prefer the MCP endpoints (streamable HTTP):
   https://api.noerrands.com/c/mail/mcp
   https://api.noerrands.com/c/fax/mcp
   https://api.noerrands.com/c/booking/mcp
   https://api.noerrands.com/c/tables/mcp
   https://api.noerrands.com/c/ship/mcp
   https://api.noerrands.com/c/prints/mcp
   https://api.noerrands.com/c/cards/mcp
   https://api.noerrands.com/c/sign/mcp
   If you use the REST APIs instead, each brief links its OpenAPI document.

4. Before you mail anything, fax anything, book anything, contact a
   restaurant, buy a shipping label, order prints, send a card, or send a
   document for signature, show me exactly what will happen, what it costs
   and who it goes to. Then wait for my explicit approval.
   Never act without asking me first. Signing links go out only from my own
   email, after I approve each message.

5. Save this as a reusable skill called "No Errands".

6. When it is set up, check it works by asking for my balance (free), then
   tell me in a few lines what I can ask you for. Offer to try it with
   something free: a document I sign myself (my first one is free) or a
   price quote for a letter. Do not spend my credits to test it.

Plain text version: /muse-prompt.txt. Then see full pricing or add credits.
