What operators are saying
Real quotes from real customers are landing as v0.1 rollouts go live. Placeholders below show the shape; they will be replaced as customers give the green light to publish.
" Once we plug Claude into our SellerCloud catalog, the morning ops cycle drops from 45 minutes to 5.
" The vendor-anomaly alerts paid for the year in the first month. We caught a $9k duplicate bill on day three.
" Read-only by default is the right answer. I trust Claude with the books because the MCP server literally cannot mutate them.
