}Frequently asked questions
What is the Neo4j MCP server?
It is a Model Context Protocol (MCP) server — a small piece of software that gives AI assistants like Claude a secure, governed connection to Neo4j. Graph database with schema inspection and Cypher query support. Explore relationships and graph structures.
Is there an official Neo4j MCP server?
Yes. The Neo4j MCP server is an official integration, maintained by the vendor or the Model Context Protocol project, which makes it the safest default for business use. It is maintained by Neo4j.
Is the Neo4j MCP server hosted, or do I run it myself?
It runs locally. Your AI client starts it on your own machine with python, and it talks to the client over standard input and output rather than the network.
Do I need an API key for the Neo4j MCP server?
Yes. The local server reads NEO4J_MCP_URI, NEO4J_MCP_USERNAME, NEO4J_MCP_PASSWORD from its environment, so you create those credentials first and add them to your client's config.
What can an AI assistant actually do with Neo4j?
Through this server an assistant can work with cypher, graph queries, schema, relationships — reading from and acting on Neo4j directly instead of you copy-pasting between windows. What you allow it to do is controlled by the permissions you grant.
How do I set this up for my business?
The setup section above has copy-paste config for Claude Code, Claude Desktop, Cursor and VS Code. If you want it rolled out across a team with permissions, governance and support handled, that is what Crox's Build engagement covers.

Want this connected to your business — with governance handled?
Crox maps your processes, connects AI to the tools you already use, and keeps it working as models change. Start with a readiness assessment or talk to us about a build.
