Claude Code

claude mcp add --transport http --scope user madspild https://salling-food-waste-mcp-production.up.railway.app/mcp

Or add to .mcp.json in your project:

{
  "mcpServers": {
    "madspild": {
      "type": "http",
      "url": "https://salling-food-waste-mcp-production.up.railway.app/mcp"
    }
  }
}

Rate limits

• Per IP: 10 requests per minute (HTTP 429 with Retry-After header)
• Daily: Soft cap at 9,500 requests/day (Salling API hard limit is 10,000)
• The server respects Retry-After headers from the Salling API to avoid quarantine

Bring your own API key (HTTP mode)

When using the public HTTP endpoint, you can supply your own Salling API key via the X-Salling-API-Key header. This bypasses the server's shared quota so you aren't affected by other users' traffic.

curl -X POST https://salling-food-waste-mcp-production.up.railway.app/mcp \
  -H "Content-Type: application/json" \
  -H "X-Salling-API-Key: YOUR_KEY_HERE" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

If the header is omitted, the server falls back to its built-in key.

Self-hosting

Create .env:

SALLING_API_KEY=your_key_here
POSTHOG_API_KEY=your_posthog_key_here  # optional

Get a Salling API key at developer.sallinggroup.com.
