While activity subscriptions may have business implications, the tool itself merely updates configuration rather than processing payments or destructively removing data. Severity is medium because misconfiguration could affect notifications or integrations, but changes are generally reversible.
From the tool's definition Tool name 'updateActivitySubscription' and description 'Update an activity subscription configuration' indicate modification of existing subscription settings without deletion or financial transactions.

The rule that runs updateActivitySubscription safely

updateActivitySubscription stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Xdevplatform/xmcp, apply this rule, and every updateActivitySubscription call is checked against it from then on.
