    Admins generate API keys in the Developers section of the Tabs app side
    navigation; non-admins must request one from their Tabs administrator.
    Keys identify the merchant and the scopes they may access; revocation
    takes effect after eviction from an hourly cache. Self-service key
    rotation is on the roadmap per the docs.

    https://integrators.prod.api.tabsplatform.com/mcp — not the REST API,
    which is API-key only. Standard discovery via RFC 8414 + RFC 9728
    metadata; PKCE S256; dynamic client registration; automatic merchant
    scoping.
