I’m consistently getting “upstream request timeout” when using MCP execute_sql and apply_migration for very simple DELETE operations.
Simple SELECT queries return quickly (<1s).
DELETE by a single ID sometimes works, but often times out.
Small batch DELETEs (even 5–7 rows) almost always time out.
apply_migration also times out on the same DELETE statements.
Error: {"error":{"name":"Error","message":"upstream request timeout"}}
I’ve confirmed there are no foreign key references blocking these deletes.
