Google ADK + Neo4j Integration

Overview

Google ADK (Agent Development Kit) is a framework for building AI agents that can leverage external tools and data sources. This integration enables Google ADK agents to connect to Neo4j via the Neo4j MCP server, providing access to Cypher query execution, schema introspection, and more.

Installation

Follow the Neo4j MCP documentation for server setup and prerequisites (Neo4j instance, APOC plugin, etc.).
