Atlassian's MCP Server and Teamwork Graph CLI Crossed 1M Monthly Active Users, Doubling in One Quarter
Atlassian's Q4 FY2026 results (August 6) reported $1,766M revenue up 28%, cloud revenue $1,213M up 31%, and subscription ARR of $6,606M up 23% — but the number aimed at builders is that its MCP server and Teamwork Graph CLI passed one million monthly active users, more than doubling in a single quarter, with a 3x increase in automations as customers deployed agents across HR, legal, finance and marketing. Atlassian did not quantify any revenue or margin contribution from that usage. Meanwhile FY27 guidance is 13% revenue growth and 18% subscription ARR growth, a clear deceleration from the 23% just posted — a million agent-facing MAUs and decelerating ARR is precisely the gap the per-agent metering debate is about.
