Run LanguageTool in Even

Even Stacks launches LanguageTool 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 LanguageTool in the one-click services and click Launch.
  3. Even pulls the image, starts it on port 8010, and serves it over trusted HTTPS at https://languagetool.localhost.

Drive LanguageTool with your AI agents

Even ships an MCP, so any agent you run inside Even (Claude Code, Codex, and more) can operate LanguageTool directly, at both the UI level and the container level.

Through the Even MCP an agent can pull a model, call the local endpoint, and wire it into a tool, all on your own hardware. 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 LanguageTool and get it ready", and the agent handles it end to end.

How agents reach it: POST text to http://localhost:8010/v2/check with parameters text=<text>&language=en-US to receive grammar suggestions as JSON. A basic web UI is available at http://localhost:8010 for manual checks. The service is stateless with no persistent data.
