Description

This MCP server integrates Neo4j with Claude Desktop so agents can execute Cypher queries, create nodes, and create relationships via natural language. It supports Neo4j Enterprise by allowing selection of a specific database and accepts parameters to avoid injection attacks. The server exposes tools for query execution and CRUD-style graph operations and is configurable via environment variables for URI, credentials, and database name.
