Ask

In a chat, ask v0 to use your Prefer data, for example “Use Prefer to find the questions buyers ask that our site doesn’t answer, then draft a page for the first one.”
v0 runs MCP tools according to its tool mode, so it may ask before it uses a Prefer tool. Prefer’s tools only read data, so they never change anything in your workspace.
