Why it matters

Shadow MCP servers create ungoverned, unvetted pathways from AI agents into sensitive corporate systems, expanding an invisible attack surface that most asset-discovery and access-review processes do not track.

An explainer on "shadow MCP servers" argues that developers connect AI assistants to real systems (Google Drive, Notion, browser extensions) via config files that skip normal SaaS vetting, leaving organizations with no inventory of what their AI agents can reach. The piece discusses why standard discovery tools miss these connectors and offers practices for finding and governing them, citing Check Point research on Claude Code MCP vulnerabilities (CVE-2025-59536, CVE-2026-21852).
