# NanoAgent Compliance Hub
[](http://mscbuild.github.io/)
## Multi-Agent Expense Auditing Platform
An AI-powered expense auditing system that combines:
* Multi-Agent Architecture (Google ADK concepts)
* MCP Server Integration
* Prompt Injection Defense
* PII Redaction
* Human-in-the-Loop Approval
* FastAPI Dashboard
* Docker Deployment
---
## Problem Statement
Organizations process thousands of expense reports every month.
Challenges include:
* Manual review overhead
* Fraud detection
* Policy compliance
* Sensitive data leakage
* Prompt injection attacks against AI reviewers
Traditional rule engines lack flexibility, while standalone LLM solutions introduce security risks.
---
## Solution
NanoAgent Compliance Hub uses multiple specialized agents:
1. Security Agent
2. Compliance Agent
3. Risk Scoring Agent
4. Manager Approval Agent
These agents collaborate to review expenses while maintaining security and transparency.
