IMtoAgent — IM ↔ Agent Unified Gateway

Connect Feishu, Telegram, personal WeChat, and WeCom to AI coding agents like Claude Code, Codex (GPT), OpenCode, and more.

One gateway, multiple IMs, multiple agents, unified port proxy.

🚀 Quick Start (5 Minutes)

Step 1: Install (One Command)

curl -fsSL https://imtoagent.pages.dev/install.sh | bash

This script detects your environment, installs bun if needed, installs imtoagent, and guides you through setup.

Step 2: Start

imtoagent setup

The interactive wizard guides you through:

1. Select IM platform (Feishu/Telegram/WeChat/WeCom)
2. Enter Bot credentials
3. Choose Agent backend (Claude Code/Codex/OpenCode)
4. Configure model providers (API keys)
5. Generate soul files for personality injection

Step 2: Verify

imtoagent status    # check it's running

That's it! Send /help to your Bot in the IM to see available commands.

Alternative install methods: See Installation Methods below for npm global install or source install.

Architecture

IM Platform (Feishu/Telegram/WeChat/WeCom)
    → IM Registry Factory → Bot Instance
        → AgentRuntime SDK → Agent Adapter
            → Unified Proxy (:18899) → Upstream Models

Supported IM Adapters

Supported Agent Backends

Quick Start

Prerequisites

• Bun runtime (≥1.0.0): brew install oven-sh/bun/bun
• macOS / Linux
• At least one Agent backend (see table below; can be installed before or after imtoagent)

Installation Methods

Method 1: One-Click Install (Recommended)

curl -fsSL https://imtoagent.pages.dev/install.sh | bash

This script does everything automatically:

• Detects your OS and environment
• Installs bun if missing
• Installs or upgrades imtoagent
• Runs the setup wizard if no configuration exists
• Starts the gateway and verifies it's running

Flags:

• --non-interactive — Skip all prompts, auto-install and auto-start
• --skip-bun — Skip bun installation check
• --skip-start — Don't start the gateway after install

Method 2: npm Global Install

npm install -g imtoagent

This is the simplest approach. After installation, the post-install script checks if you need initial configuration.

Method 3: Source Install

git clone https://github.com/imtoagent/imtoagent.git
cd imtoagent
bun install
bun run bin/imtoagent setup

Use this for development or if you want to modify the source code.

Prerequisites

• Bun runtime (≥1.0.0): brew install oven-sh/bun/bun
• macOS or Linux
• At least one Agent backend installed (see below)

Agent Backend Installation

You can install backends before or after installing imtoagent.

Configuration

First-Time Setup

imtoagent setup

The interactive wizard will guide you through:

1. Configure Bot — Select IM platform + Agent backend combination
2. Configure Model Providers — Add API credentials (DeepSeek, Dashscope, etc.)
3. Generate Soul Files — Create personality files (rules.md, identity.md, etc.)
4. Write Config Files — Auto-generate ~/.imtoagent/config.json

Platform-Specific Requirements

Feishu

• App ID (cli_...) and App Secret
• Enable in Feishu app console: Bot, Event Subscription, Message Send/Receive permissions

Telegram

• Bot Token from @BotFather
• Optional: HTTP proxy (e.g., http://127.0.0.1:7890)

Personal WeChat

• QR code automatically appears on first imtoagent start
• Scan with WeChat on your phone to complete binding

WeCom (Enterprise WeChat)

• Webhook callback URL configuration
• REST API credentials

Running the Gateway

Basic Commands

Upgrading

Upgrade IMtoAgent itself:

imtoagent update-system

This runs npm update -g imtoagent and verifies the new version.

Upgrade agent backends:

# Auto-detect current Bot's backend and upgrade it
imtoagent update-backend

# Upgrade a specific backend
imtoagent update-backend codex
imtoagent update-backend claude
imtoagent update-backend opencode

The command detects how each backend was installed (npm, brew, or manual) and uses the correct upgrade command automatically.

Running Modes

Running Modes

• start — Background mode, terminal returns immediately
• run — Foreground mode, real-time logs, Ctrl+C to stop
• daemon — Foreground with auto-restart on crash

Linux (systemd)

Create /etc/systemd/system/imtoagent.service:

[Unit]
Description=IMtoAgent Gateway
After=network.target

[Service]
Type=simple
User=youruser
WorkingDirectory=/home/youruser/.imtoagent
ExecStart=/usr/bin/bun run /usr/lib/node_modules/imtoagent/index.ts daemon
Restart=on-failure
RestartSec=5

[Install]
WantedBy=multi-user.target

systemctl daemon-reload
systemctl enable imtoagent
systemctl start imtoagent

Troubleshooting

Common Issues

Gateway won't start

• Check imtoagent status for details
• Verify config with cat ~/.imtoagent/config.json
• Check logs: cat ~/.imtoagent/logs/*.log

Setup wizard stuck

• Ensure terminal supports interactive input
• Try running in a standard terminal (not IDE integrated)

Bot not responding in IM

• Verify credentials in config.json
• Check IM platform permissions (Feishu events, Telegram webhook, etc.)
• Ensure the gateway is running: imtoagent status

Port 18899 already in use

• Another service is using the proxy port
• Kill the existing process or change port in config

Getting Help

• Check logs: ~/.imtoagent/logs/
• Run imtoagent status for runtime information
• Open an issue on GitHub with logs attached
