The most builder-actionable MCP security guide published to date. Three threat areas: LLM interaction vulnerabilities (indirect prompt injection, supply chain rug pulls, tool poisoning), local server misconfigurations (exposed credentials in ~/.cursor/mcp.json), and third-party server vulnerabilities (tool name collision, consent fatigue). Datadog's AI Guard (in preview) provides real-time MCP protection with prompt protection, tool protection, and anomaly detection. Essential reading for anyone deploying MCP in production.
