MCP Security: What the Most Popular Enterprise MCP Integrations Actually Mean for Your Governance Program
Every MCP connection establishes a persistent trust relationship between an AI agent and the system it connects to. The agent authenticates to the MCP server once, establishing a session within which multiple tool calls can occur. What happens inside that session - which data is accessed, which actions are taken, which instructions the agent follows - is governed by the MCP server itself. Most enterprise identity governance stacks have no visibility into this layer.
