Sandbox / fictional. The button below makes two real MCP calls from your browser to the public Fairplug sandbox. The offers, sponsors and links are made-up examples: nothing is tracked, nothing is paid, and no real advertiser is involved. Fairplug is an early pilot.
An agent calls search_offers to find offers, then get_tracked_link for the one it picks. The response includes a disclosure_text that the agent must show beside the link.
