The 2026 development
Google Cloud announced a work agent connecting tools, skills and business applications.
The governance gap
Every connector is an authority boundary. A work agent that can read CRM, write ERP and send email needs per-system scope, not one broad service account.
Where CAIN-42 fits: Moat 2 — Security-Context Continuity
Core question: Does authority survive every boundary? Identity, scope and delegation are carried across tools, agents, memories and systems.
Put every connector behind the MCP/API boundary with a per-tool allowlist and a per-tenant credential. CAIN's MCP proxy evaluates the tool, arguments and blast radius before forwarding.
How the wiring works
- Register each business system and tool with an owner and risk class.
- Grant the agent a per-tool, per-tenant credential.
- Inspect arguments for destructive or exfiltrating patterns.
- Log the forwarded call and the observed result.
What is real today
LIVE A public route in this deployment exercises this mechanism today, within its stated scope.
The MCP proxy and demo are real. There is no Google Cloud work-agent integration.
