A chatbot that only answers is a content problem. An agent that calls tools is an access-control problem. MCP servers, memory stores, and loop limits turn that into an estate problem.
OptimaTrust records agent cards: tools, data, memory, autonomy, approvals, MCP, APIs, and loop limit. Boundaries are ALLOWED, RESTRICTED, APPROVAL_REQUIRED, or DENIED. The Governor decide API stores ALLOW or DENY against policy-to-code rules.
What we do not claim: silent intercept of every third-party agent runtime. Honesty is part of assurance. Declared boundaries plus recorded decisions plus tests against the APIs you own — that is the operating model.
Security teams should put MCP servers on the same register as models. If it can act, it is an asset.
