Verification

After setting up VSCode/GitHub Copilot, verify Container Use is working:
  1. Check MCP Connection: VSCode should recognize Container Use tools
  2. Test Environment Creation: Ask Copilot to create a new environment
  3. Verify Isolation: Multiple environments should work independently

​
Troubleshooting

  • Verify the cu command is in your PATH: which cu
  • Check MCP configuration syntax
  • Restart VSCode after configuration changes
  • Ensure Docker is running and accessible
  • Check file permissions for configuration files
  • Verify cu stdio command works: echo '{}' | cu stdio
  • Check your VSCode MCP server logs
  • Verify Container Use tools are enabled in settings
