01 · Install Neo4j Memory

before you install - you'll need

Set NEO4J_URL, NEO4J_USERNAME, NEO4J_PASSWORD, NEO4J_TRANSPORT, NEO4J_MCP_SERVER_HOST, NEO4J_MCP_SERVER_PORT, NEO4J_MCP_SERVER_PATH, NEO4J_NAMESPACE, NEO4J_MCP_SERVER_ALLOWED_HOSTS, NEO4J_URI, NEO4J_DATABASE before connecting. NEO4J_MCP_SERVER_ALLOW_ORIGINS is optional or environment-specific per the README.

Claude Code

claude mcp add neo4j-contrib-mcp-neo4j-servers-mcp-neo4 -- uvx mcp-neo4j-memory

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "neo4j-contrib-mcp-neo4j-servers-mcp-neo4": {
      "command": "uvx",
      "args": [
        "mcp-neo4j-memory"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

pypi package mcp-neo4j-memory - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.neo4j-contrib is GitHub-verified and matches the repo owner

06 · Neo4j Memory FAQ

What is Neo4j Memory?

A Model Context Protocol (MCP) server implementation that provides persistent memory capabilities through Neo4j graph database integration.

Is Neo4j Memory still maintained?

Yes - as of 2026-08-25, its last commit was 2026-04-10. We re-verify nightly.

How do I install Neo4j Memory?

Run `uvx mcp-neo4j-memory`. The README documents 12 environment variables (NEO4J_URL, NEO4J_USERNAME, NEO4J_PASSWORD…) to set first. Set NEO4J_URL, NEO4J_USERNAME, NEO4J_PASSWORD, NEO4J_TRANSPORT, NEO4J_MCP_SERVER_HOST, NEO4J_MCP_SERVER_PORT, NEO4J_MCP_SERVER_PATH, NEO4J_NAMESPACE, NEO4J_MCP_SERVER_ALLOWED_HOSTS, NEO4J_URI, NEO4J_DATABASE before connecting. NEO4J_MCP_SERVER_ALLOW_ORIGINS is optional or environment-specific per the README. You can also paste the ready-made client config above.

Does Neo4j Memory run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
