Atlassian launched AMP on October 7, giving every AI agent an owner, a profile and an audit trail inside Jira, Confluence and Loom. The published material is a set of design patterns, so its reach outside Atlassian's suite depends on other vendors adopting them.

MCP Atlassian releases before 0.22.0 fall back to the operator's credentials whenever an HTTP caller has no verified identity (CVE-2026-77244). HTTP deployments need the upgrade, and the endpoint should be reachable only through a management network or an authenticating proxy.

Sentinel Vault calls Claude for Confluence content review through Atlassian's Forge LLMs API, declared in a four-line manifest with no remotes and no API key. Atlassian says those egress controls do not stop misuse of access granted at install.

The gate is a pure function that imports nothing and runs under plain node. The proof it works is a six-case suite scoring 1 of 6 against the ungated resolver and 6 of 6 once the gate is wired in.

Atlassian's own validator did the grading, on 25 app briefs, on the same workstation that trained the adapter. Anyone reusing the pass rate needs briefs that look like those 25.

The content manager archives 500 items in one action on Confluence Premium, and the Last active filter that finds the candidates leaves out every page with children, including the section landing pages that go stale first.

Confluence Cloud's space export leaves blog posts out of a PDF and page comments out of HTML, and the file still finishes without a warning. What lands in it also depends on the permissions of whoever clicked.

Stratus Security's CTO says the scanner his firm wrote for its own engagements pulled them out of one client's backlog, and the previous tester missed them because ticket comments are not in anyone's standard methodology.

Linear's $99m tender at a $2.5bn mark prices existing shares rather than new capital, while the blog beneath it puts agent-created work at half the total, a composition figure Atlassian answers with a 4x quarter off an undisclosed base.

From 17 August, Jira and Confluence content trains Rovo by default. The content switch works on every plan; the metadata switch is greyed out below Enterprise, which makes governance a purchase.
