Can my AI send and verify OTP codes?
Yes. send_verification sends the code, then check_verification validates the user's response.
Can I check fraud risk for a phone number?
Yes. score_phone returns a fraud risk score based on carrier intelligence and historical data.
Can I identify if a number is mobile or landline?
Yes. get_phone_type returns whether the number is mobile, landline, VoIP, or toll-free.
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.
