Show HN: Give our AI coding runner a real task and watch it until merge

mcp4mail.online is a live page where visitors can pick a real task for an open-source mail project, confirm by e-mail, and follow the AI runner from branch to pull request, tests and merge on GitHub. The site reports 179 finished tasks in 40 days, with runners on the team's own machines, no direct main-branch access, and work hours of 8:00–18:00 Prague time on work days. The page lists current tasks such as GitHub issue templates, a self-hosting docs dry run, a README provider table and screenshots, and a mail-index unread-state fix.
