**Executive summary:** The report analyzes Model Context Protocol (MCP) security risks, documents real-world incidents (postmark-mcp supply-chain backdoor, Anthropic MCP Inspector RCE CVE-2025-49596, and Cyera's OpenClaw privilege-escalation CVE-2026-44118), and catalogs common attack patterns (confused deputy, token passthrough, tool poisoning, rogue/shadow servers). It emphasizes that MCP does not mandate authentication or access controls, highlights the high-impact consequences of compromised MCP servers (credential exposure, broad data access), and provides concrete mitigations and governance guidance including token exchange, TLS/mTLS, sandboxing, supply-chain controls, centralized gateways, inventory, and logging.
