wechat-moments 0.1.1

Post to WeChat Moments via ADB automation

wechat-moments

Post to WeChat Moments via ADB automation. Controls an Android phone running WeChat using a deterministic FSM — no LLM required for UI interaction.

Requirements

• Python 3.12+
• Android phone with USB debugging enabled, WeChat installed

Note: ADBKeyboard is required for Chinese text input and will be installed automatically on first use.

Installation

pipx (recommended)

pipx install wechat-moments

uv tool

uv tool install wechat-moments

Homebrew (macOS)

brew tap vangie/formula
brew install wechat-moments

Usage

OpenClaw Integration

To integrate with OpenClaw or other MCP clients:

Local Setup (stdio mode)

If the MCP client and Android phone are on the same machine, use stdio transport (recommended):

Add to your MCP client config (e.g., ~/.mcporter/mcporter.json):

{
  "mcpServers": {
    "wechat-moments": {
      "command": "wx-pyq-mcp"
    }
  }
}

Remote Setup (SSE mode)

If the Android phone is connected to a different machine:

1. On the machine with the phone, start the MCP server:

wx-pyq-mcp --transport sse --host 0.0.0.0 --port 8765

2. On the remote machine, configure the MCP client:

{
  "mcpServers": {
    "wechat-moments": {
      "baseUrl": "http://<phone-machine-ip>:8765/sse",
      "transport": "sse"
    }
  }
}

CLI

# Check device connection
wx-pyq status

# Post with text only
wx-pyq post "今天天气真好"

# Post with images (local paths or URLs, max 9)
wx-pyq post "周末出游" -i photo1.jpg -i photo2.jpg

# Post without preview confirmation prompt
wx-pyq post "自动发布" -i photo.jpg --no-preview

# Collect FSM test fixtures (run once with phone connected)
wx-pyq collect-fixtures -o tests/fsm/fixtures/

# Clean up expired staging / archive dirs
wx-pyq cleanup

MCP Server

The MCP server exposes tools for AI agents to post to WeChat Moments.

# Start MCP server (stdio transport, for local use)
wx-pyq-mcp

# Start MCP server with SSE transport (for remote access)
wx-pyq-mcp --transport sse --host 0.0.0.0 --port 8765

Available Tools

Tool	Description
prepare_post(text, images)	Stage assets, generate preview image, return post_id
submit_post(post_id)	Execute ADB flow and publish to Moments
get_device_status()	Check ADB connection and app installation
take_screenshot()	Capture current phone screen for debugging

Typical Workflow

prepare_post("text", ["image.jpg"])
  → returns { post_id, preview_path, ... }
  → show preview_path to user for confirmation (optional)
submit_post(post_id)
  → returns { status: "success", archive_path: "..." }

Architecture

CLI / MCP Server
      │
   preview.py   ← prepare_post: stage images, generate layout preview
      │
   submit.py    ← execute_submit: lock + FSM + archive + history
      │
  ┌───┴──────────────────────────────────┐
  │ UI FSM (poster.py)                   │  ← concurrent with ↓
  │ LAUNCH → DETECT_TAB → NAV_DISCOVER   │
  │ → OPEN_MOMENTS → [DISCARD_DIALOG]    │
  │ → SELECT_IMAGES → INPUT_TEXT → DONE  │
  └──────────────────────────────────────┘
  │ Image FSM (images.py, background thread)
  │ IDLE → PUSHING → SCANNING → READY → CLEANUP
      │
    adb.py   ← ADB commands (screenshot, tap, dump UI, push files)
    cv.py    ← tab detection, checkmark counting
    ime.py   ← ADBKeyboard Chinese text input

Device Profiles

UI coordinates are stored in profiles/<device_serial>.json. Huawei defaults are in profiles/huawei_default.json. Run wx-pyq calibrate to create a profile for a new device.
