Currently all the agentics samples give a warning:

Note

⚠ Engine 'copilot' does not support the web-search tool

We should engage with Copilot CLI on this and give a better more useful warning

1. Emit a link in the warning to a new doc page
2. On the doc page document the options for using 3rd-party MCPs (choose a couple, document them, link to their terms of service and auth needs etx)
3. Engage with Copilot CLI

Will leave this open to track (3) and until Copilot CLI has feature parity with Claude Code
