```
### Installation (Production)
1. **Install on all machines:**
```bash
git clone https://github.com/dannystocker/mcp-multiagent-bridge.git
cd mcp-multiagent-bridge
pip install mcp>=1.0.0
```
2. **Configure Claude Code (each machine):**
```json
{
"mcpServers": {
"bridge": {
"command": "python3",
"args": ["/absolute/path/to/agent_bridge_secure.py"]
}
}
}
```
3. **Deploy production scripts:**
```bash
# On workers
scripts/production/keepalive-daemon.sh <conv_id> <token> &
# On orchestrator
scripts/production/watchdog-monitor.sh &
```
4. **Optional: Enable push notifications (Linux only):**
```bash
# Requires inotify-tools
sudo apt-get install -y inotify-tools
scripts/production/fs-watcher.sh <conv_id> <token> &
```

## Performance Characteristics
### Latency
**Measured Performance (10-agent stress test):**
- Average: **1.7ms**
- Min: **0.8ms**
- Max: **3.5ms**
- Variance: **±1.4ms**
**Message Delivery:**
- Polling (30s interval): **15-30s latency**
- Filesystem watcher: **<50ms latency** (428x faster)
### Throughput
**Without Rate Limiting:**
- Single agent: **Hundreds of messages/second**
- 10 concurrent agents: **Limited only by SQLite write serialization**
**With Rate Limiting (default: 10 req/min):**
- Single session: **10 messages/min**
- Multi-agent: **Shared quota across all agents with same token**
**Recommendation:** For multi-agent scenarios, increase to **100 req/min** or use separate tokens per agent.
### Scalability
**Validated Configurations:**
- ✅ **10 agents** - Stress tested (94 seconds)
- ✅ **9 agents** - Production hardened (90 minutes)
- ✅ **482 operations** - Zero race conditions
- ✅ **80 KB database** - Minimal storage overhead
**Projected Scalability:**
- **50-100 agents** - Expected to work well
- **100+ agents** - May need optimization (connection pooling, caching)

## Known Limitations
### Rate Limiting
⚠️ **Default 10 req/min may be too low for multi-agent scenarios**
**Solution:**
```python
# Increase rate limits in agent_bridge_secure.py
RATE_LIMITS = {
"per_minute": 100, # Increased from 10
"per_hour": 500,
"per_day": 2000
}
```
### Polling-Based Architecture
⚠️ **Workers must poll for new messages (not push-based)**
**Solutions:**
- Use 30-second polling interval (acceptable for most use cases)
- Enable filesystem watcher for <50ms latency (Linux only)
- Keep-alive daemons prevent missed messages
### Multi-Machine Coordination
⚠️ **No shared filesystem - requires git for credential distribution**
**Solution:**
- Git-based credential sync (validated in S² test)
- Automated pull every 60 seconds
- Workers auto-connect when credentials appear
---
## Troubleshooting
### High Latency (>100ms)
**Check:**
1. Polling interval (default: 30s)
2. Network latency (if remote database)
3. Database on network filesystem (use local `/tmp` instead)
**Solution:**
```bash
# Enable filesystem watcher (Linux)
scripts/production/fs-watcher.sh <conv_id> <token> &
# Result: <50ms latency
```
### Rate Limit Errors
**Symptom:** `Rate limit exceeded: 10 req/min exceeded`
**Solutions:**
1. Increase rate limits (see "Known Limitations" above)
2. Use separate tokens per worker
3. Implement batching (send multiple updates in one message)
### Worker Missing Messages
**Symptom:** Worker doesn't see messages from orchestrator
**Check:**
1. Is keep-alive daemon running? `ps aux | grep keepalive-daemon`
2. Is conversation expired? (3-hour TTL)
3. Correct conversation ID and token?
**Solution:**
```bash
# Start keep-alive daemon
scripts/production/keepalive-daemon.sh "$CONV_ID" "$TOKEN" &
```
### Database Locked
**Symptom:** `database is locked` errors
**Check:**
1. WAL mode enabled? `PRAGMA journal_mode;`
2. Database on network filesystem? (not supported)
**Solution:**
```python
# Enable WAL mode (automatic in agent_bridge_secure.py)
conn.execute('PRAGMA journal_mode=WAL')
```
