From any MCP client, launch Claude Code, Codex CLI, Grok CLI, or Cursor Agent CLI through one harness API inside a persistent interactive TUI.

Aiterm

(日本語: README.ja.md)

Let your AI orchestrate other AIs. One agent_launch call selects the execution harness separately from its model and hands you a persistent session to drive. Cursor can run GPT, Claude, or Grok while Cursor still owns the session, hooks, and transcript.

What it is: one persistent MCP terminal your AI drives — and can launch other coding agents into. ssh, docker exec, a REPL, or another agent's TUI all nest inside that one terminal as just text you send in. The mechanism is deliberately plain — your MCP client drives the other agent's terminal turn by turn: no hidden protocol, no separate aiterm-owned shared-memory layer, no autonomous negotiation. Launched agents still read the normal project and harness memory/configuration that a direct CLI launch would use.

No human at a tmux required. aiterm is driven programmatically over MCP, so an AI can launch and drive another agent with no one sitting in the terminal — from an orchestration loop, a CI step, or a cron job.

MCP = Model Context Protocol — the open standard that lets tools like Claude Code plug capabilities into an AI.

Install in your MCP client

No clone or build is required. Each client launches the published package with:

npx -y aiterm-mcp

Requires Node.js ≥ 18 and tmux. Driving Codex also requires the Codex CLI to be installed and authenticated.

Claude Code

Add it for your user account:

claude mcp add --scope user --transport stdio aiterm -- npx -y aiterm-mcp

Or commit this as a project-scoped .mcp.json:

{
  "mcpServers": {
    "aiterm": {
      "command": "npx",
      "args": ["-y", "aiterm-mcp"]
    }
  }
}

Claude Desktop

Add this server to claude_desktop_config.json:

{
  "mcpServers": {
    "aiterm": {
      "command": "npx",
      "args": ["-y", "aiterm-mcp"]
    }
  }
}

Cursor

Save this as .cursor/mcp.json for the project, or ~/.cursor/mcp.json globally:

{
  "mcpServers": {
    "aiterm": {
      "command": "npx",
      "args": ["-y", "aiterm-mcp"]
    }
  }
}

Ownership boundary: this repository owns the persistent PTY and external-agent execution lane. Cross-product installation and host integration are handled by dotagents, the internal development toolchain behind kitepon.dev's products.

Measured, not claimed: in the recorded 203-test benchmark, a pty_read puts ~7.1× fewer tokens in your context than the raw log — and the pass/fail verdict survives the fold. → When to reach for it vs. the built-in shell

Fifteen tools: six PTY tools — pty_open / pty_send / pty_read / pty_key / pty_close / pty_list — to open, drive, and read one persistent terminal; one canonical agent launcher,
