Anthropic MCP

⚠️ PROMPT INJECTION RISK ⚠️

Issue

Tool responses are passed directly to the model without sanitization, allowing prompt injection attacks.

Attack

Malicious data in tool responses can:

  • Override system prompts
  • Exfiltrate conversation history
  • Manipulate model behavior

Mitigation

Implement output encoding and prompt isolation techniques.
