Tags plugin and AI Agent integration

• What the AI gets

This article describes how the Tags plugin works with the Redmine Agent plugin. Everything below needs the Agent plugin installed; without it Tags works as usual. All data and actions follow the permissions of the user and, for MCP, the scopes of the OAuth token. See MCP server and AI assistant tools for general setup.

Available in Light and PRO.

What the AI gets

• Context of an issue: the tags of the issue are part of the data the model sees when drafting and summarizing.
• MCP: get_issue, create_issue and update_issue return tags and accept tag_list (replaces all tags), add_tag_list and remove_tag_list. These arguments are offered only to users with Edit tags in the project; saving a new tag also needs Create tags.
• The OAuth application must tick the scopes edit_tags and create_tags for clients to write tags; the plugin advertises them to MCP clients automatically.

Example prompt for a client: "add the tags backend and urgent to issue #123 and remove old".
