notque SAP CC Email (Cronus)
Inspect email service status: check sending usage and list available email templates for the current project.
MCP Tools
Note: Cronus MCP tools are planned but not yet implemented in the MCP server. The skill documents the service for reference. When tools become available, they will follow the
cronus_prefix pattern.
Expected Tools (NOT YET AVAILABLE)
| Tool | Purpose | Expected Parameters |
|---|---|---|
cronus_list_senders |
List verified sender addresses | project_id |
cronus_get_usage |
Get email sending usage/limits | project_id |
Interim Workaround
Until Cronus MCP tools are available:
- Use
hermes_list_events(target_type=email/*)for email audit trail - Email configuration is typically managed via the SAP CC dashboard
Gotchas
No parameters on either tool. Both Cronus tools operate on the current project scope determined by the authenticated credentials. You cannot query a different project without re-scoping.
Usage is project-scoped, not user-scoped. The usage endpoint shows aggregate email sending statistics for the entire project, not per-user breakdowns.
Templates are pre-configured, not arbitrary. Cronus templates are set up by project administrators. You cannot create or modify templates via MCP tools — these are read-only inspection tools.
Cronus is SAP CC-specific. This is not a standard OpenStack service. It is a SAP Converged Cloud extension for managed email sending. Do not confuse with external SMTP services or third-party email providers.
Rate limits and quotas are enforced server-side. If usage shows high volume, the project may be approaching sending limits. The usage response typically includes rate/quota information.
Email sending failures are not shown here. Cronus usage shows aggregate stats. For individual delivery failures or bounces, check application logs or the Cronus dashboard (not available via MCP).
Common Workflows
Check Email Service Status
cronus_get_usage— inspect current sending volume, quotas, and status.- Verify the project has email sending enabled (non-error response).
- Check usage against limits to determine remaining capacity.
List Available Templates for Integration
cronus_list_senders— see all configured templates.- Note template names/IDs for use in application code.
- Templates define the email structure; applications provide the dynamic content.
Diagnose Email Sending Issues
cronus_get_usage— check if the project has hit sending limits.- If usage is near quota, sending may be throttled or blocked.
- If the API returns an error, the Cronus service may not be enabled for this project.
- For audit trail:
hermes_list_eventsfiltered to Cronus actions.
