Install LowlandData Resale & Secondhand in LM Studio

What you need first

• LM Studio, installed.
• Nothing else: the server runs on its publisher's machines and LM Studio connects to it.

Steps

1. In LM Studio, open the Program tab and choose Install › Edit mcp.json.
2. Add this block. If the file already has mcpServers, add only the entry inside it.

{
  "mcpServers": {
    "resale": {
      "url": "https://mcp.apify.com/?actors=lowlanddata/poshmark-scraper,lowlanddata/poshmark-sold-comps,lowlanddata/vinted-scraper,lowlanddata/kijiji-ca-scraper,lowlanddata/vinted-arbitrage-scanner,lowlanddata/vinted-sold-detector,lowlanddata/vinted-deal-monitor,lowlanddata/poshmark-brand-analytics"
    }
  }
}

3. Save the file and restart LM Studio.

Check it worked

Ask LM Studio: List the tools of resale.

If it does not start

401 Unauthorized

The endpoint wants a sign-in or a key. Sign in when LM Studio asks.

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
