Upstash tuned its MCP server after 369 coding-agent runs: delete confirmation went from 1/15 to 15/15
Upstash ran seven coding agents through live Redis tasks and found agents couldn't enable daily backups, probed Redis logs that don't exist, read 0 stats right after traffic, and deleted a named database with no confirmation. After adding redis_set_daily_backup, clearer tool text, and a type-the-name delete check, backups went from 0/15 to 15/15 and delete confirmation from 1/15 to 15/15.
