AI + MCP tools have made me feel like a different kind of PM.

I was ramping up on a new product and immediately hit a foundational question: what does an "active user" actually look like here?

Answering that meant wading through @Slack and @Notion , then turning it all into testable hypotheses. Fast.

With @Claude by Anthropic and @Venn AI , I got better research than I would have found on my own. It surfaced docs I hadn't seen yet, synthesized the most relevant data points, and drew on growth frameworks from Reforge and Elena Verna to help formulate the definition ideas.

The result: multiple candidate active user definitions, each with a validation approach. Something that would have taken 10+ hours took about 30 minutes.

I could have gotten there eventually. But 30 minutes instead of a day and a half changes what's possible in a fast-moving startup environment.

If you've explored MCPs, what workflows have you found most helpful?
