We created an open-source service for Slack for sending messages, linking tasks, and reacting to external events using a terminal. The same can be built for Mattermost.
With it, you can leverage any data and events (from centralized or decentralized tech) and automate tasks. http://bit.ly/mattermost_slack
It would be pretty straightforward to apply the same concept and create an open Mattermost service if it would be useful. Do you think this would be a helpful service/tool to have?
All feedback or suggestions are welcome. Thanks!
