Multiple Issues with vapi MCP client on web sdk:

I am trying to connect zapier mcp to vapi the agent works perfect i have followed the docs from each side accurately and tested multiple times but it doesn't work and the same error occurs (call.in-progress.error-vapifault-azure-openai-llm-failed) everytime:

example of a failed call:
0ddd16af-08e9-4e4f-8f1d-eadd057cffd5
3f3c7722-67db-4de6-ad65-40a32ea464c3

example of working call:
508a4fda-b3c1-4e23-a6bc-651d1cc6b0d4

I have an action attached to zapier which should tell me the names of the users on slack using vapi mcp client but when the call is connected it plays the background noises(office noises) ... but nothing is generated via the LLM and the call disconnects.

One more thing i'd like to point out is the docs are incorrect in a couple of places:
  1. zapier has deprecated sse and this url mentioned here: https://docs.vapi.ai/tools/mcp#1-obtain-mcp-server-url
and they've migrated to this url:
https://mcp.zapier.app/home

  1. the mcp object doesn't take a name in the request or either the types in web sdk are incorrect:
    https://docs.vapi.ai/tools/mcp#example-usage
Connect your assistant to dynamic tools through MCP servers for enhanced capabilities.
