Operating the Red - Blue - Green Teaming Loop

Operating Red Teams (proactive attack), Blue Teams (intent drift monitoring), and Green Teams (circuit breaking & remediation) in a continuous triad loop.

Organize Red Teaming exercises simulating realistic agent attacks

Implement Blue Teaming systems to detect intent and behavior drift

Build Green Teaming reflexes: circuit breakers and state remediation

Govern MCP discovery and contextual authorization

MCP spoofing exploits runtime discovery: a forged or compromised server can present a familiar tool name, return instruction-shaped content, or request privileges unrelated to the task. TLS or a valid server credential proves who answered; it does not prove that the requested call matches the user's intent.

Route every Agent-to-Tool and A2A invocation through a centralized Agent Gateway. The gateway should verify server identity and tool schema, pin approved server versions, run an LLM firewall over untrusted semantic content, and apply contextual authorization to the association among user, agent, task intent, tool, resource, and time. Returned text remains data and cannot grant itself authority.

For example, a legitimate CRM MCP server may expose both read_account and bulk_delete_accounts. A request to prepare a briefing can authorize the read tool but must reject the delete tool even though both come from the same authenticated server. The PM owns the server registry, allowed association matrix, mismatch UX, and emergency disable path. Measure unregistered-server attempts, schema drift, privilege escalation requests, tool calls lacking intent linkage, policy latency, and blocked lateral movement.
