Open a directory listing with a public contract and select Set up a watch. Sign in, then select Save baseline. You can also paste a directory listing URL or a listed endpoint into the Watch page.
Each account can save up to ten servers. Saving a baseline is free and does not start a subscription. When Watch billing is available, Activate Watch opens checkout for the monthly plan. The page shows whether email alerts are active and which account email receives them. After checkout, refresh the payment status if the confirmation has not arrived yet.
What produces an alert
Watch compares successive public, probe-recorded contracts after your saved baseline. An email identifies the tools, resources, or prompts with breaking changes and links to the listing's classified history. Compatible and cosmetic changes remain in the history and do not generate email alerts.
Watch uses the directory's scheduled probes. It is not real-time uptime monitoring. A failed connection does not prove that a tool was removed: Watch needs a newly recorded contract to classify a change. Check Last probe on the Watch page when assessing how recent the evidence is.
This first version supports public contracts from remote MCP servers. It does not probe with your credentials, compare owner-pushed contracts against public ones, or monitor WebMCP pages. Slack, webhooks, and team sharing are not included.
Stop alerts or cancel
Remove watch deletes that watch and its saved baseline, and stops its future emails. Removing watches does not cancel your subscription. Use Manage billing or cancel to open the billing portal. Email delivery pauses when the account no longer has an active, unexpired Watch subscription.
