Postmortem: MCP tool removed over the weekend, detected on scheduled poll (not prod traffic)
A SaaS team experienced a critical workflow failure when a third-party MCP tool was unexpectedly removed, causing their internal agents to malfunction. Existing monitoring systems failed to detect this issue because it did not affect their own service's uptime or traffic. After implementing DriftGuard, the team successfully detected a similar contract drift event within 35 minutes, preventing further disruption. AI
