# Tools Availability for the Step 3.7 Flash Model (StepFun Ai) > Source: > Published: 2026-06-24 16:42:45+00:00 Hi everyone !! I’m a big user of HuggingChat and more precisely of the really good Step 3.7 Flash Model. The thing is, since this morning the model can’t use tools anymore, and so MCP servers… Did anyone had this problem before ? Is this permanent? This model is really really good, and don’t want to be forced to use another. In addition, the model does not cost that much, both in ressources and in price (at least compared to other models of the same category). Thank you for your help !!
