Overview
A pattern for delegating workflow approval decisions to an AI agent that investigates system health using MCP tools and returns structured decisions with confidence scores.
Description
AI Approval Gate replaces human approval with an autonomous AI agent for lower-risk environments. The agent uses Model Context Protocol (MCP) tools to investigate the Prefect instance (querying flow patterns, checking deployments, reviewing system status) and returns a structured decision with confidence score, reasoning, and concerns. This enables:
- Graduated autonomy — start with human, move to AI
- Structured decisions with audit trail
- MCP-based system investigation
- Configurable confidence thresholds
Usage
Use this pattern when you want to graduate from human approval to autonomous AI decisions for maintenance operations in non-production environments, or where decision-making can be formalized into rules the AI can follow.
Theoretical Basis
The AI Approval Gate extends the Gate pattern by replacing the human reviewer with an AI agent. The agent follows the Investigate-Decide-Explain pattern:
- Use MCP tools to gather system context
- Make a structured decision (approved/rejected)
- Provide reasoning and confidence for auditability
