# A2A ADK MCP Pipeline

> Use this tool when you need to securely query databases using natural language and protect sensitive information from threats and exposure. It solves problems of SQL injection, data breaches, and personally identifiable information (PII) leaks by validating inputs, executing queries, and masking sensitive results. The pipeline takes in natural language queries as input and outputs masked query results through a built-in web UI.

## Description

Demonstrates a multi-agent security pipeline where three specialized agents collaborate: one validates input for SQL injection and threats, another executes natural language database queries, and a third identifies and masks personally identifiable information in results. Combines Google's Agent Development Kit (ADK), the Agent-to-Agent (A2A) communication protocol, and MCP database tools into a single orchestrated workflow with a built-in web UI.
