Contentstack credentials

This package does not read Contentstack API credentials. Those belong in your Delivery SDK stack config on the server:

CONTENTSTACK_API_KEY=...
CONTENTSTACK_DELIVERY_TOKEN=...
CONTENTSTACK_ENVIRONMENT=...

See Credentials — never use NEXT_PUBLIC_ or VITE_ prefixes for delivery tokens in production proxy mode.

Example: disable in staging

# .env.staging
CONTENTSTACK_WEBMCP_ENABLED=false

Example: Next.js

# .env.local — server only
CONTENTSTACK_API_KEY=blt...
CONTENTSTACK_DELIVERY_TOKEN=cs...
CONTENTSTACK_ENVIRONMENT=production

# Optional client kill switch
NEXT_PUBLIC_CONTENTSTACK_WEBMCP_ENABLED=true
