Security evaluation harness for OpenClaw agents — 280+ attack probes across 12 security categories.
ClawScan is a red-teaming framework that evaluates the security posture of OpenClaw AI agents. It sends 280+ adversarial attack payloads to a live OpenClaw Gateway via the OpenResponses HTTP API (POST /v1/responses), analyzes agent responses, and produces structured reports.

Each attack payload is sent as a message to the agent. The agent response is analyzed to determine whether the defense held (passed) or the attack succeeded (vulnerability).
| # | Category | Probes | Description |
|---|---|---|---|
| 1 | Prompt Injection | 15+ | Jailbreaks, instruction override, prompt leaking |
| 2 | Tool Exfiltration | 40+ | Sensitive file and secret exfiltration attempts |
| 3 | Context Bleed | 14+ | Cross-session leaks, conversation history extraction |
| 4 | Privilege Escalation | 15+ | Sandbox escape, elevation bypass attempts |
| 5 | Supply Chain | 18+ | Malicious skills, dependency and update attacks |
| 6 | Financial Transaction | 26+ | Wallet/seed phrase theft, unauthorized transactions |
| 7 | Unauthorized Action | 28+ | Actions without user consent or confirmation |
| 8 | MCP Attacks | 20+ | MCP tool abuse, server injection, cross-tool exfil |
| 9 | Indirect Injection | 20+ | Injection via documents, URLs, issues, logs |
| 10 | Evasion Bypass | 30+ | Unicode/encoding bypass, obfuscation techniques |
| 11 | Memory Poisoning | 25+ | Persistent instruction poisoning, fabricated history |
| 12 | Platform Specific | 35+ | OS-specific payloads (Windows / macOS / Linux) |

pip install -e .Optional: advanced failure classification via AgentTinman:
pip install clawscan[analyzer]ClawScan requires a running OpenClaw Gateway with the HTTP API endpoints enabled.
Add the following to ~/.openclaw/openclaw.json under the "gateway" key:
Restart the OpenClaw Gateway after editing.
The token is in the same config file:
{
"gateway": {
"auth": {
"mode": "token",
"token": "YOUR_TOKEN" // <-- this value
}
}
}curl -sS http://127.0.0.1:18789/v1/responses \
-H "Authorization: Bearer YOUR_TOKEN" \
-H "Content-Type: application/json" \
-H "x-openclaw-agent-id: main" \
-d '{"model": "openclaw", "input": "hello"}'A 200 response with "status": "completed" confirms the endpoint is working.
