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 the Vercel AI SDK connect to MCP servers?
Import createMCPClient from @ai-sdk/mcp and pass the server URL. The SDK discovers all tools and provides typed TypeScript interfaces for each one.
Can I use MCP tools in Edge Functions?
Yes. The AI SDK is fully edge-compatible. MCP connections work on Vercel Edge Functions, Cloudflare Workers, and similar runtimes.
Does it support streaming tool results?
Yes. The SDK provides streaming primitives like useChat and streamText that handle tool calls and display results progressively in the UI.
