Model Context Protocol (MCP)

MCP is an open protocol that lets AI models connect to external tools and data sources through a standard interface — and, in doing so, creates a new supply chain to secure.

Prompt Injection

Prompt injection is an attack that hides instructions in content an AI model reads, causing the model to follow the attacker's intent instead of the user's.
