GHL MCP is not available rn, Vapi support already said you have to wait till the end of the first quarter of this year to see if the issue has been solved... So if you are urgently in need of making use of GHL in your system, then you have to make use of external integration tools like make.com and n8n to connect GHL to vapi without the MCP, you can check tutorials on YouTube to see how it's done or I can guide you on call (I have blueprints I can share to you also to make it faster)... Thanks
