Run Mattermost in Even

Even Stacks launches Mattermost as a managed container on your own machine. No compose files, no manual setup.

  1. Open the Even Stacks panel in Even. The container engine starts on demand.
  2. Find Mattermost in the one-click services and click Launch.
  3. 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.

How agents reach it: Use the web UI at http://localhost:8065 or compatible desktop and mobile clients for team messaging. The REST API is at `/api/v4/` authenticated with a Bearer token from User > Security > Personal Access Tokens. Data is stored in the companion Postgres service.
