I installed a MCP into Cursor today and it works perfectly at verifying login credentials with my Supabase database. The credentials I am testing against are already inside a database I created on Supabase. However, when I asked the Agent to use inputs from a Registration page I have, it “coughed” and finally told me the MCP I am using only allows “read-only” and it can’t add DB entries from my login page for that reason…Does anyone have a recommendation on a Cursor MCP that will allow me to populate my DB with new users via the inputs they make on a Registration page?

There are MCP that can write to DBs but it makes no sense for your use case as you should rather ask it to write code that inserts the data from the form into the database directly.

Bingo,that worked! It took me about an hour of asking Cursor to do what I wanted until I figured out I needed to give it the ANON information. Once I did that, it populated the DB correctly with the user Registration info…thanks!
