Approvals for webapp triggered workflows

Questions

Hey all, hoping you can guide me on a solution related to approval functionality.

My setup is a simple one: I have a webapp and n8n workflow. Users submit queries through the webapp’s chat-interface. Content is received in the n8n workflow. Agent makes sense of request and passes information to MCP server that performs actions in a SQL database. Result of action is posted back to the webapp.

What I need is a step where we can request the user to confirm/approve the action before the MCP server performs its functions. How is this best implemented? Human in the loop has slack/telegram/gmail connectors. We use a webapp. I’m at a loss.

well you can have aiagent to always confirm before passing data to mcp server.

Hi Moosa, I’m not following your recommendation.

My understanding is that the initial webhook node receives the query from the webapp. Then we have a response webhook node that sends a message back to the webapp. Start and Finish. What if there is interaction required in the middle… You can’t do that with an AIAgent.
