Mattermost in one click.
Mattermost is a team chat (slack alt, with postgres) you can run on your own machine. Launch it in Even Stacks in one click, serve it over trusted HTTPS, and let your AI agents operate it.
What is Mattermost?
Mattermost is an open-source, self-hostable team messaging platform serving as a Slack alternative. It stores messages in PostgreSQL and supports plugins, bots, integrations, and slash commands.
Run Mattermost in Even
Even Stacks launches Mattermost as a managed container on your own machine. No compose files, no manual setup.
- Open the Even Stacks panel in Even. The container engine starts on demand.
- Find Mattermost in the one-click services and click Launch.
- Even pulls the image, starts it, and serves it over trusted HTTPS at
https://mattermost.localhost.
Drive Mattermost with your AI agents
Even ships an MCP, so any agent you run inside Even (Claude Code, Codex, and more) can operate Mattermost directly, at both the UI level and the container level.
Through the Even MCP an agent can drive its web UI, create channels or users, and post messages. It runs commands inside the container, reads its logs, and for web apps opens and clicks through the interface in Even's own browser pane. Ask once, for example "set up Mattermost and get it ready", and the agent handles it end to end.
