WHAT IT DOES

What redmine_upload does on Redmine Enhanced MCP Server

WHY IT NEEDS A POLICY

Why redmine_upload needs a policy

File uploads create new data (attachments) in the Redmine system. This is reversible (attachments can be deleted), so it qualifies as Write rather than Destructive. The severity is medium because uploaded files could contain malicious content, consume storage, or clutter issues, but the impact is generally limited to the Redmine project scope.

From the tool's definition Server description states the tool can 'upload/download attachments' and this tool is named 'redmine_upload'. The function performs file upload operations which modify server state by adding attachments to Redmine issues.
