Best Tools for Securing MCP and LLM Integrations | UpGuard

This guide outlines the security risks posed by shadow MCP servers and unsanctioned LLM integrations, recommends a two-layer approach of exposure/discovery followed by runtime defenses, lists key capabilities to evaluate (e.g., MCP inventory, lookalike detection, prompt-injection protection, least-privilege scoping, DLP, monitoring, and audit logging), and compares leading vendors to help organizations prioritize visibility before deploying runtime guardrails.
