Can my AI agent create new predictive models in Appier?

No. The MCP server is designed natively for reading data, fetching performance stats, analyzing segments, and understanding configurations. Creating complex models still requires the Appier Enterprise Console to ensure ML model safety.

How fast can I generate a campaign ROI report before a meeting?

In a few seconds. Tell your agent 'Fetch analytics for my top 3 active campaigns' and the AI will invoke the analytics endpoint, process the CPC, CTR, and ROAS data, and output a clean executive summary in whatever format you ask.

Can the agent tell me how big a specific prediction segment is?

Yes. If an audience ID or segment ID is known, the agent uses the 'get_audience' tool to fetch size estimations, AI criteria, and generation metrics—informing you immediately if your targeted audience size is large enough to launch.
