Add the Neo4j MCP server to Windsurf

Config last verified Jun 1, 2026

The exact config to run Neo4j in Windsurf — paste it in, restart, and the tools load.

Prerequisites

Windsurf installed.
NEO4J_URI — Connection URI for the Neo4j instance, e.g. bolt://localhost:7687.
NEO4J_USERNAME — Neo4j username used to authenticate.
NEO4J_PASSWORD — Password for the Neo4j user.

Setup

1. Open `~/.codeium/windsurf/mcp_config.json`

On Windows the file lives at %USERPROFILE%\.codeium\windsurf\mcp_config.json.

2. Add this configuration

Add to ~/.codeium/windsurf/mcp_config.json

~/.codeium/windsurf/mcp_config.json

json

{
  "mcpServers": {
    "neo4j": {
      "command": "python",
      "args": [
        "-m",
        "neo4j_mcp_server"
      ],
      "env": {
        "NEO4J_URI": "<NEO4J_URI>",
        "NEO4J_USERNAME": "<NEO4J_USERNAME>",
        "NEO4J_PASSWORD": "<NEO4J_PASSWORD>"
      }
    }
  }
}

3. Restart Windsurf and confirm the Neo4j tools load.

Gotchas

Windsurf's Cascade reads MCP servers from an "mcpServers" object in ~/.codeium/windsurf/mcp_config.json. Unlike most clients, remote servers are configured with the "serverUrl" field rather than "url", so a config that uses "url" silently fails to connect. Native remote transport is supported without an OAuth flow.
