Frequently asked questions
Can I send transactional SMS messages via the AI agent?
Yes! You can specify the recipient's phone number and the message content, and the AI will trigger the eSputnik SMS endpoint.
How do I query my contact segments?
Ask the agent to 'List all contact groups'. It will retrieve your active segments directly from the eSputnik API.
Does it support adding new contacts dynamically?
Absolutely. You can request the AI to add an email or phone number to your active directory instantly.
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.
