Most tools have distinct purposes, but there is some overlap between list_emails and fetch_recent_emails, as both retrieve recent emails, which could cause confusion. The other tools are clearly differentiated, such as send_email for sending and read_email for reading specific emails.

All tool names follow a consistent snake_case pattern with clear verb_noun combinations, such as download_attachment, fetch_email_thread, and send_email. This consistency makes the tool set predictable and easy to navigate for an agent.

With 8 tools, the server is well-scoped for email management, covering key operations like sending, reading, listing, searching, and handling attachments. Each tool serves a specific function without redundancy, making the count appropriate for the domain.

The tool set provides strong coverage for email operations, including CRUD-like actions (send, read, list, search) and attachment handling. A minor gap is the lack of tools for updating or deleting emails, but agents can work around this with the existing tools for most workflows.
