I cannot connect

401 unauthorized means the request has no usable Clerk OAuth token. Remove any stale connector entry, add the remote URL again, and complete the Clerk OAuth window. Individual Claude accounts use Customize → Connectors; Team/Enterprise Owners use Organization settings → Connectors. Remote connectors do not belong in claude_desktop_config.json.

I see “subscription required”

403 subscription_required means Clerk recognized the account, but it cannot pass the full access gate. Check the exact reason: tenant_binding_missing means business setup or claim is incomplete; clerk_feature_missing, inactive_subscription, or neon_feature_missing indicates a paid-plan or entitlement problem; entitlement_unavailable means no matching tenant entitlement mirror is available. Cancel-at-period-end retains access through the already-paid term. Access ends after that term, expiration, any nonpayment status including past due, or when the account is free or unprovisioned.

I see another server error

403 origin_not_allowed means the MCP client origin is not approved; it is not a billing failure. 503 unavailable means the Clerk authority or Neon entitlement-mirror read is temporarily unavailable, so access failed closed. Send Intelligence Help the exact error text, but never a token, password, cookie, or key.
