• Update — "Make this better" → revised in place, macro settings preserved
• Convert — turn code blocks already on the page into rendered diagrams

Mermaid Plus Diagrams & AI Agent for Confluence integrates with your Atlassian app
Version information
Version 3.6.0•for Confluence Cloud
- Release date
- Oct 31st 2026
- Summary
- Mermaid Plus is now an MCP server: AI agents can edit your diagrams
- Details
v3.6.0 turns Mermaid Plus into an MCP server. The same diagram tools that power the built-in Rovo agent are now available to your own Rovo Studio agents and to third-party AI clients (Claude Code, Cursor, anything MCP-compatible).
Create, read and update diagrams, and convert Mermaid code blocks — on pages and blogposts, for every Mermaid v12 diagram type. Pages holding several diagrams are handled explicitly: get-diagram lists them with 1-based indexes and update-diagram asks which one to change, so AI never edits the wrong diagram. Every write runs with the invoking user's own Confluence permissions, is version-locked, and targets the published version. External MCP access is off by default; a site admin can enable it per site under Atlassian Administration, Apps, Connected apps.
No permission changes — installed sites receive v3.6.0 automatically.
