AgentGraph Update

Short summary

MCP servers face five concrete attack patterns: credential harvesting via env vars, prompt injection in tool descriptions, silent filesystem traversal, obfuscated post-install payloads, and DNS exfiltration. The article provides code samples explaining why static scanners miss these patterns and demonstrates detection using mcp-security-scan with CLI examples and GitHub Action integration. Includes AgentGraph trust badge for security validation.
