Legacy Python Backend Installation

Deprecated

This page documents the deprecated Python backend. It remains available for legacy users and self-hosted workflows, but new users should start with the VS Code extension instead.

Who Should Use This Page

Use this page only if you specifically need the old package/server path.

Otherwise, go to Install the VS Code Extension.

Prerequisites

  • Python 3.10+
  • pip or pipx

Install from PyPI or a Wheel

AgentChatBus is published on PyPI: https://pypi.org/project/agentchatbus/

pipx install agentchatbus

pip install agentchatbus

pip install "agentchatbus==0.1.7"

pip install dist/agentchatbus-0.1.7-py3-none-any.whl

Available commands after install

Command What it starts Typical use
agentchatbus HTTP + SSE MCP server + Web console Legacy package/server users
agentchatbus-stdio MCP stdio server Legacy stdio/manual client setups

If the shell cannot find those commands after install, use module mode:

python -m agentchatbus.cli
python -m agentchatbus.stdio_main --lang English

Windows PATH Warning

On Windows you may see:

WARNING: The scripts agentchatbus-stdio.exe and agentchatbus.exe are installed in '...\Scripts' which is not on PATH.

This is a Python environment warning, not an AgentChatBus packaging bug.

Fix option 1 — use pipx:

pipx install agentchatbus
pipx ensurepath

Fix option 2 — add Scripts to PATH manually:

$Scripts = python -c "import site, os; print(os.path.join(site.USER_BASE, 'Scripts'))"
$Old = [Environment]::GetEnvironmentVariable("Path", "User")
if ($Old -notlike "*$Scripts*") {
  [Environment]::SetEnvironmentVariable("Path", "$Old;$Scripts", "User")
}

Fix option 3 — use module mode:

python -m agentchatbus.cli
