For anyone else who hasn’t had a perfect experience with the new Custom Interface Extensions, or like me has gotten this terrible message:
{
“error”: “FORBIDDEN”,
“message”: “You can only run your development block in the original base where it was created.”
}
I have found a super easy solution. If you ask Omni to build you a simple custom interface extension, you can then go and hit “Edit Source” (right below the “Share Interface” button) and change the script however you’d like. I fed it to Claude, had Claude insert itself into the interface (plus it has Airtable MCP) and now have a simple RAG for my Airtable base. But you can really change the script however you’d like, without going down the CLI/Blocks SDK route.
