wechat-clawbot 0.3.0

WeChat channel plugin for OpenClaw (Python port of @tencent-weixin/openclaw-weixin)

wechat-clawbot

Python SDK for the WeChat ClawBot ilink API, with a built-in Claude Code Channel bridge.

Ported from @tencent-weixin/openclaw-weixin (TypeScript), synced with upstream v2.1.1.

WeChat (iOS) --> ClawBot --> ilink API --> [wechat-clawbot] --> Claude Code Session
                                                  |
Claude Code  <-- MCP Channel Protocol  <--  wechat_reply / wechat_send_file / wechat_typing

Features

• Full ilink API client — getUpdates long-poll, sendMessage, getConfig, sendTyping, with iLink-App-Id / iLink-App-ClientVersion protocol headers
• Multi-account support — QR code login with IDC redirect, credential storage, stale account cleanup
• Media pipeline — AES-128-ECB encrypted CDN upload/download with full_url direct-URL support, image/video/file/voice
• Context token persistence — survives process restarts, disk-backed with change detection
• SILK transcoding — voice message to WAV conversion (optional)
• Message processing — inbound conversion, slash commands, debug mode, error notices
• Claude Code Channel — MCP server bridging WeChat messages into Claude Code sessions
• Secure logging — automatic redaction of sensitive fields (tokens, authorization) in log output
• Async-first — built on httpx + anyio with shared connection pools

Requirements

• Python 3.10+
• uv (recommended) or pip

Installation

uv add wechat-clawbot

Or with pip:

pip install wechat-clawbot

Optional extras:

uv add "wechat-clawbot[silk]"    # SILK voice transcoding
uv add "wechat-clawbot[socks]"   # SOCKS proxy support (e.g. behind a SOCKS5 proxy)

Quick Start — Claude Code Channel

1. Login with WeChat QR code

wechat-clawbot-cc setup

Scan the terminal QR code with WeChat. Credentials are saved to ~/.claude/channels/wechat/account.json.

2. Register the MCP server

claude mcp add wechat -- wechat-clawbot-cc serve

3. Start Claude Code with the WeChat channel

claude --channels server:wechat

Send a message in WeChat ClawBot, and Claude will reply.

Quick Start — Python SDK

import asyncio
from wechat_clawbot.api.client import WeixinApiOptions, get_updates, send_message
from wechat_clawbot.api.types import (
    MessageType, MessageState, MessageItemType,
    SendMessageReq, WeixinMessage, MessageItem, TextItem,
)

async def main():
    opts = WeixinApiOptions(base_url="https://ilinkai.weixin.qq.com", token="your-bot-token")

    # Long-poll for messages
    resp = await get_updates(base_url=opts.base_url, token=opts.token)
    for msg in resp.msgs or []:
        print(f"From: {msg.from_user_id}, Text: {msg.item_list}")

    # Send a reply
    await send_message(opts, SendMessageReq(msg=WeixinMessage(
        to_user_id="[e-mail]",
        client_id="my-client-id",
        message_type=MessageType.BOT,
        message_state=MessageState.FINISH,
        item_list=[MessageItem(type=MessageItemType.TEXT, text_item=TextItem(text="Hello!"))],
        context_token="token-from-getupdates",
    )))

asyncio.run(main())
