Hey, thanks for your reply. I have just a description in each tool of the MCP what the tools is used for. I use the MCP not only for voice calls but also for other channels so I can't put out some text before the tool itself is running hope you understand or is this in your opinion needed for making it fluent? The same MCP works very good when using it in Retell, so it should not cause the delay in VAPI. I really would appreciate her help.
