Human-in-the-Loop Automation: When AI Should Ask for Approval
Human-in-the-loop automation is a design where automated processes and AI agents handle routine work, but pause for a person to review or approve at defined points. It combines the speed of automation with human judgment where it matters.
When to require human approval
- Irreversible actions such as deleting data or sending payments.
- High-value decisions above a financial threshold.
- Customer-facing communications with legal or commercial impact.
- Low-confidence AI results, such as unclear document extraction.
- Publishing changes to live apps and workflows.
When not to
- Routine, reversible steps with clear rules.
- Read-only lookups and reports.
- Notifications and internal updates.
Designing good approval steps
- Show the approver everything needed to decide in one place.
- Let them approve where they work: Slack, Teams, email or an app.
- Set deadlines, reminders and escalation.
- Log the decision with the reason.
- Review approval rates: if almost everything is approved, consider automating it.
Human in the loop for AI assistants
When AI assistants connect to business systems through MCP, approvals can be set per tool. For example, reading data is always allowed, while running a write flow or publishing an app needs confirmation.
In Noca
Noca flows include approval steps with notifications in Slack and Teams. The Noca MCP Server lets you set each tool to always allow, needs approval or blocked, and destructive actions require confirmation.
