That's the line I'd read first, because whoever steals the backend's client ID and secret gets every connected user's Gmail and Slack, not a tool call. The agent-facing design is careful. Virtual MCP servers mint per-user session tokens from 60 seconds to 24 hours, one hour by default, scoped to that user's connected accounts, so the agent can be kept away from the raw credential.
