Describe the problem/error/question
I would like to use the PostgreSQL MCP Server custom node referenced in this official workflow:
However, when I import the workflow into n8n Cloud, it shows the error:
“This node is not currently installed. It is either from a newer version of n8n, a custom node, or has an invalid structure.”
Is it possible to install or activate this node in my n8n Cloud instance?
What is the error message (if any)?
“This node is not currently installed. It is either from a newer version of n8n, a custom node, or has an invalid structure.”
Please share your workflow
I’m using the official MCP Server template from:
Share the output returned by the last node
Not applicable – the workflow can’t run without the custom node.
