The Model Context Protocol (MCP) is identified as a critical component in managing AI assistant context, making its servers vulnerable to prompt injection attacks.
- Prompt injection allows malicious users to manipulate an AI assistant's behavior or extract sensitive information by bypassing initial instructions.
- Attack types include direct injection (overwriting system prompts) and indirect injection (embedding malicious prompts in external data accessed by the AI).
- Defense strategies involve sanitizing inputs, implementing strong access controls, employing AI firewalls, and establishing a human review process for critical outputs.
- Best practices for developers include robust input validation, output filtering, and continuous monitoring to detect and mitigate injection attempts.
