Why it matters
MCP servers are a fast-growing attack surface for agentic AI, and this checklist helps defenders identify and remediate concrete weaknesses like prompt injection via tool results and weak tenant isolation before attackers exploit them.
Rick Hightower's article presents a TypeScript-focused security-review checklist for Model Context Protocol (MCP) servers, enumerating 14 production gaps including shared API keys, missing audit logs, prompt-only guardrails, prompt injection through tool results, weak tenant isolation, non-idempotent mutations, schema drift, unmanaged secrets, and missing DLP, plus a maturity scorecard. It offers code patterns to close the most dangerous gaps and hardening guidance for moving MCP servers from demo to production.
