I dont think is something in specific but I used to love the simplicity of PostHog and that's why I pushed my team moving to it from Google Analytics.
That has changed though. Last time I used PH, I found myself not finding the things I needed so ended up connecting the mcp and asking claude to change things for me.
MCP was a nice addition, so thanks for that. The problem of mcp is that it prevents product discoverability. You are adding many things lately and since I'm using the MCP for my "part of the job" I will never visit your site anymore and see what's new.
I've notice that as well. If you don't know how to do something having an agent with tools is great (in general, not just PH). But, its also quite slow and imprecise. I think that having the agent act more as both a teacher and "doer" is best.
