Read-Only Mode

The server can be run in read-only mode by setting the KUZU_READ_ONLY environment variable to true. In this mode, running any query that attempts to modify the database will result in an error. This flag can be set in the configuration file as follows:

{
    "mcpServers": {
        "kuzu": {
            "command": "docker",
            "args": [
                "run",
                "-v",
                "{Absolute Path to the Kuzu database}:/database",
                "-e",
                "KUZU_READ_ONLY=true",
                "--rm",
                "-i",
                "kuzudb/mcp-server"
            ],
        }
    }
