[Closed] Does this website exist?

Has anyone came across a service that lets you type in your postcode and then you're presented with a list of your local councillors, MPs, MEP (I guess not anymore!), etc

There is a page on the .gov.uk that looks helpful, but all it does is point you towards the local authority website.

Assuming there isn't, does anyone know whether publishing a list of councillors name and contact details would contravene GDPR regs? I'm involved in a community action group, and we'd like to make it easy for people to lobby their democratic reps - the details are all on the local council websites but they are somewhat buried.
