SPR{K}3 Defend Agents
Runtime security for AI agents — detects jailbreak, prompt injection, and tool misuse from inside the agent, not at the gateway.
Install
pip install sprk3-defend-agents
Quick Start
from sprk3.defend import monitor
monitor(api_key="sk-...")
That's it. Auto-instruments Anthropic, OpenAI, and LangChain clients.
What it detects
- Indirect prompt injection — hidden instructions in web pages, emails, docs, tool outputs
- Tool misuse — legitimate tools used on attacker's behalf
- Agent tamper — heartbeat detects monitoring disabled or bypassed
- Behavioral anomaly — tool velocity spikes, entropy shifts, new tool usage
Privacy
All detection runs client-side. Server sees metadata only. Evidence stays on your machine.
