easiest one to get going with is to add the Playwright MCP. As a python dev you might have used it to do test automation? Anyway, it gives your tool eg Cursor, Claude Code access to the browser and automation using playwright. Meaning it can literally load a page to confirm its own change just had the desired effect.

The blender one is also fun as a starting point, if you do any 3d modelling (or even if you don't).
