Frequently asked questions
How do I submit multiple emails for validation at once?
Use the validate_bulk tool and provide an array of email addresses in the emailList parameter. The server will return a trackingId which you can use to check the results.
How can I check if my bulk validation task is finished?
You can use the get_validation_status tool by providing the trackingId received during the submission. It will return the current progress or the final validation results.
Is there a way to prevent sending the same validation request twice?
Yes, when using validate_bulk, you can provide an optional hashkey. This unique string prevents duplicate requests from being processed within a 3-minute window.
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.
