I have found MCPs helpful. Recently, I used one to migrate a site from WordPress to Sanity. I pasted in the markdown from the original site and told it to create documents that matched my schemas. This was much quicker and more flexible than whipping up a singular migration tool. The Sanity MCP uses oAuth so I also didn’t need to do anything in order to connect to my protected dataset. Just log in. I’ll definitely be using this method in the future for different migrations.
