WeChat Image Sending Limitations & Workarounds

Problem

WeChat does NOT expose a direct API for sending images programmatically. The only supported way via MCP tools is mcp_android_phone_send_wechat_message which only handles text.

What We Tried

1. Android Intent Sharing (am start -a SEND)

• Opens WeChat's ShareImgUI activity
• Result: Opens a contact picker UI, requires manual selection
• Status: Partially works, but not fully automated

am start -a android.intent.action.SEND -t image/png \
  --eu android.intent.extra.STREAM file:///sdcard/Pictures/WeChat/daily_digest.png \
  -n com.tencent.mm/.ui.tools.ShareImgUI

2. UI Automation (Click "+" → Album → Select Image → Send)

• Result: Unreliable - button coordinates vary by device/screen size
• Status: Failed - cannot consistently locate the "+" button or album icon

3. FileProvider / ContentProvider

• Result: Would require WeChat-specific permissions
• Status: Not feasible without modifying WeChat's manifest

4. Frida Hooking

• Result: Requires Mac bridge (frida_bridge.py) not available in Termux
• Status: Not feasible in current environment

Current Workaround

1. Generate image with Pillow → save to /sdcard/Pictures/WeChat/
2. Send text summary via mcp_android_phone_send_wechat_message
3. User manually sends image from gallery if needed

Future Solutions

Option A: phoneuse Script

Build a dedicated phoneuse script that:

1. Opens specific chat via am start with chatroom ID
2. Uses accessibility service to find and click "+" button
3. Navigates to album
4. Selects image by filename
5. Clicks send

Option B: WeChat Web Hook

If user has WeChat PC client running, could use:

• Windows COM automation
• Or a third-party WeChat bot framework (risky, may violate ToS)

Option C: Alternative Delivery

• Upload image to temporary hosting (imgur, etc.)
• Send link to group
• Or send as email attachment

Recommendation

For now, use the text summary + manual image approach. The text summary captures all key information; the image is a nice-to-have visual enhancement.
