I Built an Agent That Assembles Incident War Rooms in Notion Through MCP

This is a submission for the Notion MCP Challenge What I Built Incident Runbook is an agent that turns Notion into a living incident response system. It watches an Incidents database, and when a new SEV1 or SEV2 appears, it cross-references three other databases (Services, Runbooks, On-Call), assembles a War Room page with everything the responder needs, and writes it back to Notion. When the incident is marked resolved, it generates an AI post-mortem with Gemini 2.5 Flash. The whole thing runs through Notion's MCP server. No REST calls, no webhooks, no middleware layer.
