   - name: AI Inference with GitHub Tools
     id: inference
-    uses: actions/ai-inference@v1
+    uses: actions/ai-inference@v1.2

       prompt: 'List my open pull requests and create a summary'
       enable-github-mcp: true
+      token: ${{ secrets.USER_PAT }}
 ```

 perform actions like searching issues and PRs.
 
-**Note:** MCP integration requires your workflow token to have appropriate
-GitHub permissions for the operations the AI will perform.
+**Note:** For now, MCP integration cannot be used with the built-in token. You
+must pass a GitHub PAT into `token:` instead.
