Why it matters
Shadow MCP connections represent an ungoverned expansion of agent privilege and tool reach that defenders must inventory and control before it becomes a hidden bridge into sensitive systems.
A glossary entry from NHI Management Group defines a "Shadow MCP Connection" as an unreviewed or unsanctioned Model Context Protocol connection created outside formal security oversight, which can bypass approval, expand an agent's effective access, and create governance blind spots. The reference piece describes how such hidden integrations enlarge an agent's blast radius and references the MCP authorization specification and the OWASP Agentic Applications Top 10.
