### Describe the solution you'd like

I setup playwright test for e2e testing with aspire and for it run correctly I need to run it through aspire so env is correctly setup. the agent is able run playwright through the aspire and this is great. But I want do one more step that allow agent run a specific test instead of running everything because there a lot of test case and that very time consuming. I check the document and we have prompt to custom the args before running the service https://aspire.dev/extensibility/interaction-service/#prompt-for-user-input but look like mcp is not yet support this. So it will be nice that mcp support to allow the agent to then the prompt input too.
