# Overview

Akto Probe Library is the AI Red Teaming framework for teams protecting AI agents, LLM components, and MCP endpoints. Write custom probes to discover vulnerabilities specific to autonomous systems including prompt injections, tool abuse, and permission escalation.

Probe Library consists of three blocks:

1. [Probe Library](/akto-argus-agentic-ai-security-for-homegrown-ai/probe-library/agentic-security-categories.md) with 4000+ built-in probes for agentic security
2. [YAML](/akto-argus-agentic-ai-security-for-homegrown-ai/probe-library/concepts/test-yaml.md) probe editor for custom probe creation
3. Sample agent component requests and responses for scanning
