Claude Tag operates as Anthropic's on-call agent for CI/CD failures, monitoring Slack, Grafana, Datadog, and GitHub via MCP connectors to detect and triage incidents.

It publishes a first analysis with a median of 14 minutes after an incident opens, using parallel orchestrator-executor agents to identify root causes. Anthropic open-sourced an on-call setup kit on GitHub that converts a team's incident history into triage playbooks for replicating the workflow.
