+### Running Without uv (Using System Python)
+
+If you prefer to use the system Python installation instead of uv, you can install the package from PyPI and run it directly:
+
+1. Install the package using pip:
+   ```bash
+   python3 -m pip install mcp-clickhouse
+   ```
+
+   To upgrade to the latest version:
+   ```bash
+   python3 -m pip install --upgrade mcp-clickhouse
+   ```
+
+2. Update your Claude Desktop configuration to use Python directly:
+
+```json
+{
+  "mcpServers": {
+    "mcp-clickhouse": {
+      "command": "python3",
+      "args": [
+        "-m",
+        "mcp_clickhouse.main"
+      ],
+      "env": {
+        "CLICKHOUSE_HOST": "<clickhouse-host>",
+        "CLICKHOUSE_PORT": "<clickhouse-port>",
+        "CLICKHOUSE_USER": "<clickhouse-user>",
+        "CLICKHOUSE_PASSWORD": "<clickhouse-password>",
+        "CLICKHOUSE_SECURE": "true",
+        "CLICKHOUSE_VERIFY": "true",
+        "CLICKHOUSE_CONNECT_TIMEOUT": "30",
+        "CLICKHOUSE_SEND_RECEIVE_TIMEOUT": "30"
+      }
+    }
+  }
+}
+```
+
+Alternatively, you can use the installed script directly:
+
+```json
+{
+  "mcpServers": {
+    "mcp-clickhouse": {
+      "command": "mcp-clickhouse",
+      "env": {
+        "CLICKHOUSE_HOST": "<clickhouse-host>",
+        "CLICKHOUSE_PORT": "<clickhouse-port>",
+        "CLICKHOUSE_USER": "<clickhouse-user>",
+        "CLICKHOUSE_PASSWORD": "<clickhouse-password>",
+        "CLICKHOUSE_SECURE": "true",
+        "CLICKHOUSE_VERIFY": "true",
+        "CLICKHOUSE_CONNECT_TIMEOUT": "30",
+        "CLICKHOUSE_SEND_RECEIVE_TIMEOUT": "30"
+      }
+    }
+  }
+}
+```
+
+Note: Make sure to use the full path to the Python executable or the `mcp-clickhouse` script if they are not in your system PATH. You can find the paths using:
+- `which python3` for the Python executable
+- `which mcp-clickhouse` for the installed script
+
 ## Development
 
 1. In `test-services` directory run `docker compose up -d` to start the ClickHouse cluster.
