LABSCO SUMMARY

Interactive terminal apps, driven and checked by an agent.

For anything that runs in a terminal, the agent can launch it, press keys, wait for a prompt and capture the screen to check it looks right.

What it is

An MCP server from the Hex1b project, a .NET library for building interactive terminal apps. It lets an AI assistant open terminal sessions, type into them, press keys and read what is on screen, the way a person would. The shells are real and run as your user; nothing is sandboxed.

What you get

  • Bash terminal sessions started, listed, resized, stopped and removed
  • Text and special keys sent: Enter, Tab, arrow keys, function keys
  • The screen captured as plain text or as an SVG image
  • A wait until specific text appears on screen
  • Sessions recorded to asciinema files for playback

Requirements

.NET 10 or later, installed as a .NET global tool with dotnet tool install -g Hex1b.McpServer. Linux or macOS. No account or key. MIT licensed.

Setup effort

One command — dotnet tool install -g Hex1b.McpServer
