thinkfleetai Feishu Bridge
Bridge Feishu bot messages to ThinkFleet Gateway over local WebSocket.
Architecture
Feishu user → Feishu cloud ←WS→ bridge.mjs (local) ←WS→ ThinkFleet Gateway → AI agent
- Feishu SDK connects outbound (no inbound port / public IP needed)
- Bridge authenticates to Gateway using the existing gateway token
- Each Feishu chat maps to a ThinkFleet session (
feishu:<chatId>)
Setup
1. Create Feishu bot
- Go to open.feishu.cn/app → Create self-built app → Add Bot capability
- Enable permissions:
im:message,im:message.group_at_msg,im:message.p2p_msg - Events: add
im.message.receive_v1, set delivery to WebSocket long-connection - Publish the app (create version → request approval)
- Note the App ID and App Secret
2. Store secret
mkdir -p ~/.thinkfleet/secrets
echo "YOUR_APP_SECRET" > ~/.thinkfleet/secrets/feishu_app_secret
chmod 600 ~/.thinkfleet/secrets/feishu_app_secret
3. Install & run
cd <skill-dir>/feishu-bridge
npm install
FEISHU_APP_ID=cli_xxx node bridge.mjs
4. Auto-start (macOS)
FEISHU_APP_ID=cli_xxx node setup-service.mjs
launchctl load ~/Library/LaunchAgents/com.thinkfleet.feishu-bridge.plist
Diagnostics
# Check service
launchctl list | grep feishu
# Logs
tail -f ~/.thinkfleet/logs/feishu-bridge.err.log
# Stop
launchctl unload ~/Library/LaunchAgents/com.thinkfleet.feishu-bridge.plist
Group chat behavior
Bridge replies only when: user @-mentions the bot, message ends with ?/？, contains request verbs (帮/请/分析/总结…), or calls the bot by name. Customize the name list in bridge.mjs → shouldRespondInGroup().
