This is the experimental bleeding-edge version of Neo4j's MCP server, designed for testing new capabilities before they land in the official release. It connects to Neo4j databases (Aura, Desktop, or self-managed) and requires the APOC plugin installed. The server supports both stdio transport for desktop clients and HTTP mode with per-request authentication for web integrations. It performs startup checks in stdio mode to verify connectivity and APOC availability, while HTTP mode skips validation and starts immediately. Expect breaking changes between releases and no official support. Use this if you want early access to experimental graph database features and can tolerate instability.
