Scored across 13 tools
Each tool has a distinct purpose with no overlap: cancel_email, check_api_status, create_contact, get_domain, get_email, get_sms, list_audiences, list_contacts, list_domains, list_emails, send_email, send_sms, and validate_email all target specific resources and actions. An agent can easily differentiate between them.
Tool names follow a consistent verb_noun pattern throughout, such as cancel_email, create_contact, get_domain, list_audiences, send_email, and validate_email. This uniformity makes the set predictable and easy to navigate.
With 13 tools, the server is well-scoped for email and SMS marketing operations. Each tool serves a clear function, covering core workflows like sending, listing, getting details, and managing contacts without unnecessary bloat.
The toolset provides strong coverage for email and SMS operations, including CRUD-like actions for contacts, sending, and status checks. Minor gaps include no update or delete tools for contacts or audiences, but agents can work around this with existing tools.
