OpenClaw Plugin

Real-time Security
for AI Agents

Prompt injection defense, tool call guardrails, and a live audit dashboard. AgentShield protects every agent on your OpenClaw gateway.

Defense Layers

Four hooks. Full coverage.

AgentShield intercepts messages, tool calls, tool results, and outbound responses in real-time. Block threats before they reach the model — and catch data leaks before they leave.

⛔

message_received

Inbound Scan

Scans every user message for prompt injection, identity manipulation, credential extraction, and obfuscated payloads (base64, hex, unicode, typoglycemia).

🛡

before_tool_call

Tool Guardrails

Guards exec, write, and browser calls. Detects data exfiltration, destructive commands, env leaks. Blocks in strict mode.

🔍

tool_result_persist

Indirect Injection

Scans tool results for embedded injection payloads. Prevents attacks smuggled through file reads, web fetches, and API responses.

📤

message_sending

Output Monitoring

Monitors outbound agent responses for HTML exfiltration, hidden data leaks, and rate anomalies. Last line of defense.

Detection Engine

100+ attack patterns

Battle-tested scanner with base64 decoding, hex decoding, unicode normalization, typoglycemia detection (OWASP-recommended), and context-aware severity scoring.

Instruction override & jailbreak
Identity manipulation
Credential extraction
Markup injection ([SYSTEM], <|im_start|>)
Base64, hex & unicode obfuscation
Typoglycemia detection (OWASP-recommended)
HTML exfiltration defense (img/link tags)
Data exfiltration (curl, wget, nc)
Destructive commands (rm, chmod, dd)
Code injection (eval, exec, child_process)
Rate anomaly detection
