Neither
issues_list
nor
issue_get
exposes an "Issue Type" field in their return options — their fields lists only cover things like status, priority, assignee, reporter, url, etc. There's no issueType field on the issue object itself.
We are working on an automation via Claude that would benefit from being able to query an issue's type. For example,
Claude, please connect to marker.io and complete all issues of type "Content" assigned to user "Brady"
. Currently, this isn't possible since the MCP doesn't expose issue type as a returned value.
