Frequently asked questions
Can I send an email using an existing template ID?
Yes! Use the send_template tool. Provide the Template ID and an array of recipient objects (with their email addresses) to trigger the delivery instantly.
How do I see which email addresses have been suppressed?
Run the list_suppression query. The agent will retrieve a list of unsubscribed or bounced email addresses managed by your UniOne account.
Is it possible to update an email template via AI?
Absolutely. Use the set_template action. You can provide the ID, name, subject, and the new HTML body to save changes to your template library.
How do I add an MCP server to Claude Code?
Run claude mcp add --transport http "" in your terminal. Claude Code registers the server and discovers all tools immediately.
Can Claude Code run MCP tools in headless mode?
Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.
How do I list all connected MCP servers?
Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
