Change UVX to UVENV, add Python version recommendation, update Claude config file

[nielsdejong]

I had some trouble running the MCP server following along with the release blog post:
https://medium.com/neo4j/claude-conversing-with-neo4j-via-mcp-5419d24bb7a0

When first trying to run the MCP server from Claude desktop, I got this issue:

2025-01-03T08:07:42.199Z [info] Attempting to connect to MCP server movies-neo4j...
2025-01-03T08:07:42.204Z [error] Error in MCP connection to server movies-neo4j: Error: spawn uvx ENOENT
2025-01-03T08:07:42.204Z [error] Could not start MCP server movies-neo4j: Error: spawn uvx ENOENT
2025-01-03T08:07:42.205Z [info] MCP server movies-neo4j disconnected. For troubleshooting guidance, please visit our [debugging documentation](https://modelcontextprotocol.io/docs/tools/debugging)

I managed to fix this by doing two things:

1. Updating Python from 3.9 to 3.13.
2. Doing a pip install uvenv and switching out uvx for uvenv in the config file.

I also realized that somehow the CLI params with the uri, username, password were not accepted.
I had to add another -- inside the args array in the config.

This was my final claude_desktop_config.json:

{"mcpServers": {
      "movies-neo4j": {
        "command": "/Users/nielsdejong/.pyenv/shims/uvenv",
        "args": ["run",
		 "mcp-neo4j-cypher", 
                 "--", "--db-url", "neo4j+s://demo.neo4jlabs.com", 
                 "--user", "recommendations", 
                 "--password", "recommendations"]
      }   
    }
 }

It could be that this is just me, but it might be worth checking to see if this happens on a fresh environment as well.
