modbender OneBot Adapter
Connect OpenClaw to OneBot protocol servers like NapCat for QQ bot functionality.
Quick Start

2. Receive Messages
Use the WebSocket listener script to receive QQ messages:
python scripts/onebot_ws_listener.py
3. Send Messages
Use HTTP API to send messages:
from scripts.onebot_client import OneBotClient
client = OneBotClient()
client.send_private_msg(user_id=123456, message="Hello!")
client.send_group_msg(group_id=789012, message="Group message")
Connection Modes
WebSocket (Recommended)
- Real-time bidirectional communication
- Receives events instantly
- Supports both sending and receiving
HTTP
- Request-response model
- Good for simple sending
- Requires polling for receiving
Common Tasks
Get Login Info
client.get_login_info()
Get Friend/Group List
client.get_friend_list()
client.get_group_list()
Handle Messages
See references/message-handling.md for message parsing and response patterns.
NapCat Specific
NapCat is a OneBot11 implementation based on NTQQ.
Default ports:
- WebSocket: 3001
- HTTP: 3000
- WebUI: 6099
Token authentication is optional but recommended for public deployments.
Troubleshooting
Connection refused: Check if OneBot server is running and ports are correct.
Authentication failed: Verify token matches OneBot server configuration.
