  "mcpServers": {
    "madspild": {

Rate limits

• Per client: 10 requests per minute by default (HTTP 429 with Retry-After header)

• Daily: Process-local soft cap at 9,500 shared-key requests (Salling API hard limit is 10,000)

• The server respects Retry-After headers from the Salling API to avoid quarantine

The hosted endpoint does not accept API keys from clients. Self-hosted operators can explicitly enable X-Salling-API-Key overrides with ALLOW_API_KEY_OVERRIDE=true, but should do so only on a trusted deployment because the credential passes through that server.

Self-hosting

Create .env:

SALLING_API_KEY=your_key_here
POSTHOG_API_KEY=your_posthog_key_here  # optional
TRUSTED_CLIENT_IP_HEADER=
TRUSTED_PROXY_HOPS=0
ALLOW_API_KEY_OVERRIDE=false

Get a Salling API key at developer.sallinggroup.com. For direct connections, leave TRUSTED_CLIENT_IP_HEADER empty and keep TRUSTED_PROXY_HOPS=0. Behind a trusted proxy, configure either an authoritative client-IP header or the number of trusted X-Forwarded-For hops. The included Railway deployment trusts Railway's overwritten X-Real-IP header.

Privacy

The server does not enable analytics unless POSTHOG_API_KEY is configured. When enabled, it sends request and rate-limit event names with a truncated SHA-256 hash of the client IP as the distinct identifier; it does not send locations, product results, or API keys. API-key overrides are disabled by default.
