I had completed the GHL integrations in the VAPI voice agents, and it was working fine until yesterday. Now, I am encountering this error.

Thank you for sharing the error details. The message "Failed to connect to MCP server" suggests a connectivity or authentication issue between your Vapi agent and the MCP server, which is required for GHL tool calls. To help diagnose further, have you recently changed your MCP server URL, API key, or network settings? If not, are you able to access the MCP server endpoint (e.g.,

https://mcp.vapi.ai/mcp

) from your environment? If everything appears unchanged, you may also want to check the [Vapi status page](https://status.vapi.ai/) or reach out to [Vapi support](https://docs.vapi.ai/support) or their [Discord community](https://discord.gg/pUFNcf2WmH) for real-time assistance.

Thanks for the response. I haven’t configured any custom MCP setup on my end. I’m just using the predefined tools available in the Vapi dashboard and only passing parameters like the contact ID, etc. Everything was working fine for the past three days without any issues. I haven’t made any changes to my configuration, so I’m not sure why this error is suddenly appearing today. Would appreciate your help in resolving this.
