Frequently asked questions
Can my AI send SMS and track delivery status?
Yes. Use send_sms to deliver a text message, then get_sms_status with the returned message ID to check delivery confirmation in real time.
How does phone verification work through the AI?
Two steps: first, send_verification sends an OTP code to the user's phone. Then, check_verification validates the code the user submits. Both operations run through the 8x8 Verify API.
Can I send messages through WhatsApp and other chat channels?
Yes. The send_chat_message tool supports WhatsApp, Viber, and LINE. Just specify the channel, recipient identifier, and message text.
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.
