GuardrailAI

Autonomous Regulatory Guardrail Agent using MCP and Google Gemini

GuardrailAI is an AI-powered compliance agent that evaluates file write requests before execution. By combining deterministic policy validation with Google Gemini reasoning, it detects sensitive information, explains compliance decisions, and prevents insecure data storage through an auditable governance workflow.

Problem

AI-powered applications frequently generate and write sensitive information such as passwords, API keys, personally identifiable information (PII), and confidential business data. Traditional rule-based validation lacks contextual reasoning and explainability, making governance and compliance difficult.

GuardrailAI ensures every file write request is evaluated before execution, reducing security risks while providing transparent, explainable decisions.

Solution

GuardrailAI processes every request through an AI-driven compliance pipeline:

• Policy-based security validation

• Sensitive data detection

• Google Gemini compliance reasoning

• Risk score calculation

• Automated approval or rejection

• Immutable audit logging

• Live governance dashboard
