Terminal MCP App

An MCP App that renders an interactive xterm.js terminal inline in Claude Code and Claude Desktop. Multi-session PTY support via node-pty with tabbed UI.

Yo dawg, I heard you like Claude, so I put Claude in your Claude so you can Claude while you Claude.

• Multi-Session Tabs: Create, switch, close, and customize terminal sessions

• Tab Customization: Set names, colors, and icons per tab via LLM tools

Tools

• terminal-show — Opens the terminal UI and spawns one or more sessions. Accepts optional tabs array (each with command, cwd, name, color, icon), height, and width. Defaults to one bash tab.

• terminal-create — Spawns additional sessions without re-rendering UI. Same tabs options as terminal-show.

• terminal-list (App-only) — Lists all sessions with IDs, labels, titles, and style.

• terminal-write (App-only) — Writes data to a PTY session. Omit data to poll the output buffer.

• terminal-read — Returns ANSI-stripped terminal history (last 10k chars). Non-destructive.

• terminal-resize (App-only) — Resizes PTY to match UI dimensions.

• terminal-refresh (App-only) — Sends SIGWINCH to force running programs to redraw.

• terminal-close (App-only) — Kills a PTY session and removes it.

• terminal-customize — Sets name, color, and/or icon on a tab.
