If I want to connect n8n to ai voice platform like Vapi, Retell, Elevenlabs, there are two ways. The first one is connecting each individual workflow as tool with webhook and referencing to the specific tool in the prompt. The second one is putting all the workflows into one mcp server, connecting that mcp server to ai voice platform and letting the agent decide, which tool it has to use (f.e. Booking appointment, new crm entry,…). Which way is the best for which usecase? I find it easier to do the mcp, because i dont have to prompt the agent which tool to use that much, but im worried about accuracy (using the right tool) and latency (doesn’t it take more time when it also has to find the tool?). Which one do you use, and which one is the best for which use case?

Hi! I’ve got a question, how can I make my ai agent be able to recognise past customers ? (Do I need to build a new tool that’s connected to a Google sheet file so that the bot can save infos or gather infos form that file — and I will Properly also need to tell my bot to also check tha file before stating a conversation to be able to regonise past costumers or create new ones) right ?

I'm working on a Ai receptionist for Car Detailers but I am stuck on the amount of functions that it should have? I feel as if I don't have enough functions in order to start selling to clients? Does anyone have any tips or suggestion on what functions to have for my receptionist?
