Vercel AI SDK returns empty text after MCP tool call resolution

[Vineetttt30]

Description

When invoking a tool via experimental_createMCPClient() and generateText using the Vercel AI SDK, the final .text field in the response is always an empty string, even though the tool result contains valid data.

Issue replicates even with maxToolRoundtrips: 3 set.
