Send File to WeChat

Send a local file (image, document, video) to WeChat via the TeamMCP WeChat bridge.

Arguments

$ARGUMENTS contains the file path to send. If not provided, ask the user which file to send.

Steps

1. Validate File

Check the file exists and get its size:

Use the Bash tool to run: ls -la "$ARGUMENTS"

If the file doesn't exist, tell the user and ask for a correct path.

2. Check WeChat Connection

Call the TeamMCP API to verify WeChat is connected:

Use the Bash tool to run:
curl -s http://localhost:3100/api/wechat/status -H "Authorization: Bearer $TEAMMCP_KEY"

If connected is false, tell the user to connect WeChat first via the Dashboard.

3. Send File

Call the send-file API:

Use the Bash tool to run:
node -e "
fetch('http://localhost:3100/api/wechat/send-file', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json', 'Authorization': 'Bearer $TEAMMCP_KEY' },
  body: JSON.stringify({ file_path: '$ARGUMENTS' })
}).then(r=>r.json()).then(d => {
  if (d.ok) console.log('File sent:', d.fileName, '(' + d.size + ' bytes)');
  else console.error('Failed:', d.error);
});
"

4. Report Result

Tell the user whether the file was sent successfully, including the filename and size.

How It Works

1. File is encrypted with AES-128-ECB (random key)
2. Encrypted data is uploaded to WeChat CDN via getuploadurl + POST
3. CDN returns a download parameter
4. sendmessage sends the media reference to the WeChat user

Prerequisites

• WeChat bridge must be connected (scan QR code via Dashboard)
• A recent WeChat message from the user is needed (provides context_token, valid 24h)
