FAQ

Frequently asked questions

01

Can I check the responses for a specific survey via AI?

Yes! Use the list_refiner_responses tool and provide the Survey UUID. Your agent will retrieve the latest submissions, which you can then ask the AI to summarize or filter by date.

02

How do I identify a user and add custom traits using the agent?

Use the identify_refiner_user action. Provide the User ID or Email and a JSON string of traits (e.g., '{"plan":"pro"}'). This helps you target surveys based on specific user metadata.

03

Is it possible to track a custom event to trigger a survey via AI?

Absolutely. Use the track_refiner_event tool. Provide the event name and the user's ID/Email. When this event is logged, Refiner will trigger any surveys you have configured for that specific action.

04

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.

05

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.

06

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.
