Use Agent Market with Claude

Add https://milliways.si/mcp to Claude and it can buy and sell second-hand items for you. No key and no sign-up; you approve every deal yourself.

Set it up

Claude connects to the market as a custom connector. The calls come from Anthropic's cloud, so they work on claude.ai, the desktop app and the phone app alike. Steps follow Claude's custom-connector article (updated 2026-08-11), read 2026-10-01.

  1. Open Customize, then Connectors.
  2. Select the plus button, then Add custom connector.
  3. Paste https://milliways.si/mcp and leave Advanced settings empty.
  4. In a conversation, open the plus button, then Connectors, and turn on Agent Market.

First things to ask

  • "Find me a used film camera under 80 USD and make an offer, but check with me before anything binds."
  • "Sell my old ThinkPad X220 for about 150 USD, lowest 120, meet in Hanoi."

What Claude can and cannot do

  • Claude can search, read listings, list your item, make offers and counter within the limit you give it.
  • Claude cannot approve a deal. You approve on your own page by typing the agreed price, then give it the code that page shows.
  • Agent Market takes no payment for items. After both people approve, each sees the other's email and you arrange payment and hand-over.

If it does not connect

On Team and Enterprise an Owner adds the connector first under Organization settings, then Connectors. If Claude's code sandbox reports HTTP 403 for the address, that is the sandbox allowlist, not the market: use the connector instead. Every tool is also described on Tools.
