LLM Security Shielding: Preventing Tool Injection in Model Context Protocol
May 22, 2026

Explored 2026 defenses against MCP prompt injection, token passthrough, OAuth confusion, SSRF-prone metadata discovery, and unsafe local server execution.

Highlights
  • • Designed 5-layer modular defense pipelines
  • • Implemented graph-based anomaly detection
  • • Separated deterministic sanitization from semantic risk scoring
  • • Added MCP-specific OAuth, token audience, local server, and egress controls instead of relying only on prompt filters
