+#### Using Python MCP Servers with uv
+
+For Python-based MCP servers managed with `uv`, you need to specify the directory containing your server:
+
+```yaml

+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}

+            "args": [
+              "--directory",
+              "${{ github.workspace }}/path/to/server/",

+      }
+    allowed_tools: "my-python-server__<tool_name>" # Replace <tool_name> with your server's tool names
+    # ... other inputs
+```
+
+For example, if your Python MCP server is at `mcp_servers/weather.py`, you would use:
+
+```yaml
+"args":
+  ["--directory", "${{ github.workspace }}/mcp_servers/", "run", "weather.py"]
+```
+
 **Important**:
 
 - Always use GitHub Secrets (`${{ secrets.SECRET_NAME }}`) for sensitive values like API keys, tokens, or passwords. Never hardcode secrets directly in the workflow file.
