Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
[](https://smithery.ai/server/@alanse/mcp-neo4j-server)
An MCP server that provides integration between Neo4j graph database and Claude Desktop, enabling graph database operations through natural language interactions.
Quick Start
You can run this MCP server directly using npx:
npx @alanse/mcp-neo4j
Or add it to your Claude Desktop configuration:
{
"mcpServers": {
"neo4j": {
"command": "npx",
"args": ["@alanse/mcp-neo4j-server"],
"env": {
"NEO4J_URI": "bolt://localhost:7687",
"NEO4J_USERNAME": "neo4j",
"NEO4J_PASSWORD": "your-password",
"NEO4J_DATABASE": "neo4j"
}
}
}
}Features
This server provides tools for interacting with a Neo4j database:
Neo4j Enterprise Support
This server now supports connecting to specific databases in Neo4j Enterprise Edition. By default, it connects to the "neo4j" database, but you can specify a different database using the NEO4J_DATABASE environment variable.
Tools
execute_query: Execute Cypher queries on the Neo4j database- Supports all types of Cypher queries (READ, CREATE, UPDATE, DELETE)
- Returns query results in a structured format
- Parameters can be passed to prevent injection attacks
create_node: Create a new node in the graph database- Specify node labels and properties
- Returns the created node with its internal ID
- Supports all Neo4j data types for properties
create_relationship: Create a relationship between two existing nodes- Define relationship type and direction
- Add properties to relationships
- Requires node IDs for source and target nodes

Questions
What is the Neo4j MCP server?
mcp-neo4j-server
What tools does Neo4j expose?
3 in total: 0 read-only, 3 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is Neo4j safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does Neo4j need?
It reads NEO4J_PASSWORD from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does Neo4j run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as @alanse/mcp-neo4j-server at 0.2.0.
How current is this page?
The grade is for one exact copy of the source (acce3a7525c0), read on 2026-10-07. The repository is watched and re-audited when it changes.
