Hey, thanks for the report.
A couple of questions to help debug. What transport type is your Bugsnag MCP using, HTTP or stdio? Stdio servers run inside the VM and depend on the environment. HTTP servers are proxied through the backend. This can affect how Automations see MCP.
Also, did you enable the MCP tool when creating the automation, in the list of available tools?
Let me know the details above so we can narrow it down.
