Alert: [FIRING:1] OpenClaw Gateway Unavailable — MCP Bridge Down
Source
OpenClaw local host (stdio MCP transport)
Message
Firing
The OpenClaw MCP gateway process has stopped responding on the host machine.
opensre integrations verify openclaw is returning:
OpenClaw bridge validation failed: Connection closed.
Hint: The `openclaw mcp serve` bridge needs a running OpenClaw Gateway.
Check `openclaw gateway status`, then start it with `openclaw gateway run`
(foreground) or `openclaw gateway install` followed by `openclaw gateway start`.
All three bridge tools (list_openclaw_tools, search_openclaw_conversations,
call_openclaw_bridge_tool) are permanently unavailable for the duration of the outage.
Investigation write-back to OpenClaw is also failing.
Labels:
- alertname = OpenClawGatewayUnavailable
- severity = critical
- service = openclaw-gateway
- environment = local
- pipeline_name = openclaw_mcp
Annotations:
- error = Connection closed
- command = openclaw mcp serve
- last_successful_heartbeat = 2026-05-11T08:34:00Z

Fault Injection Script
The following script reproduces this alert against a real local OpenClaw install:
#!/usr/bin/env bash
# inject_gateway_crash.sh — stop the OpenClaw gateway to trigger the alert
set -euo pipefail
echo "[inject] Stopping OpenClaw gateway..."
openclaw gateway stop 2>/dev/null || pkill -f "openclaw gateway" 2>/dev/null || true
echo "[inject] Verifying fault is active..."
sleep 1
opensre integrations verify openclaw && echo "ERROR: gateway still up" && exit 1 || true
echo "[inject] Fault confirmed. Gateway is down."
echo "[inject] Run 'opensre investigate' with the alert JSON above to get RCA."
echo "[inject] To restore: openclaw gateway start"
