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 Windsurf discover MCP tools?
Windsurf reads the mcp_config.json file on startup and connects to each configured server via Streamable HTTP. Tools are listed in the MCP panel and available to Cascade automatically.
Can Cascade chain multiple MCP tool calls?
Yes. Cascade is an agentic system. it can plan and execute multi-step workflows, calling several tools in sequence to accomplish complex tasks without manual prompting between steps.
Does Windsurf support multiple MCP servers?
Yes. Add as many servers as needed in mcp_config.json. Each server's tools appear in the MCP panel and Cascade can use tools from different servers in a single flow.
