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 does Cline connect to MCP servers?
Cline reads MCP server configurations from its settings panel in VS Code. Add the server URL and Cline discovers all available tools on initialization.
Can Cline run MCP tools without approval?
By default, Cline asks for confirmation before executing tool calls. You can configure auto-approval rules for trusted servers in the settings.
Does Cline support multiple MCP servers at once?
Yes. Configure as many servers as needed. Cline can use tools from different servers within the same autonomous task execution.
