KYE Protocol™ proves who was allowed to act — and lets anyone verify it. Microsoft’s AGT is a capable, open way to _build_ governed agents inside one stack. **[KYE Protocol™](https://kyeprotocol.com/)** sits one layer up and is deliberately different: a vendor-neutral **authority** and **evidence** layer that decides admissibility at the moment of the action and seals a [Replay-Proof™ Evidence Pack™](https://kyeprotocol.com/evidence-pack/) you verify offline from a published key — across any agent framework. When an agent acts, you prove who authorised it in seconds, cutting audit exam-prep from days to minutes. [Start a governed pilot](https://kyeprotocol.com/poc/) [Verify a live decision](https://kyeprotocol.com/trust-self-audit/) ## Two honest layers, not a strawman This is a fair comparison drawn from Microsoft’s public AGT specifications (an MIT-licensed, Python-first project with ten published specs). Their toolkit and KYE Protocol™ answer different questions, and the honest framing is “which layer” — not “which is better at the other’s job”. You can run both; the question is where the _authority decision_ and the _portable proof_ live. ## Where KYE Protocol™ has the upper hand A toolkit helps you build a governed agent; a protocol lets a regulator, an auditor or a counterparty _believe_ the result without trusting you or your vendor. These are the dimensions where, for a CISO or a DPO buying for audit defensibility, KYE Protocol™ is the stronger answer. | Dimension | Microsoft AGT (public specs) | KYE Protocol™ | | --- | --- | --- | | Primary job | Toolkit to build governed agents (policy, identity, execution control, MCP gateway, audit) | Authority + evidence protocol — decides who may act and proves it | | Stewardship | Microsoft-stewarded open source (MIT) | Vendor-neutral protocol + open standard; public schemas, ID format, Apache-2.0 Constitution Kit™ | | Decision moment | Policy evaluation within the toolkit | Purpose Permission™ + Authority Finality™ — refuse at the moment of the action, not after | | Proving a past decision | Audit & compliance logging | Replay-Proof™ — re-derive any decision offline from a published JWKS, with no vendor in the loop | | Agent identity | Agent identity & trust | Agents as first-class principals — identity, authority bindings, memory authority, metering, directory | | Regulatory mapping | Framework adapters; OWASP Agentic Top 10 | 249 frameworks with per-requirement bindings (EU AI Act™, NIST AI RMF, ISO/IEC 42001™, DORA) | | Runtime stance | Includes execution control of the agent runtime | Governs, does not run — one neutral overlay across every agent framework | | Edge & offline | Not in the public ten-spec set | KYE™ Edge Governance™ — four modes plus an offline evidence log | Comparison compiled from Microsoft’s publicly published AGT specifications as of June 2026; capabilities evolve, so verify the current specs before a procurement decision. “Not in the public ten-spec set” describes the published specification scope, not a claim about every internal capability. ## The difference, in one picture A toolkit’s proof tends to live where the agent runs. KYE Protocol™ detaches the proof from the runtime: the decision is signed and the verification key is published, so you — or your auditor, or a court — re-derive it independently, even years later and even if KYE™ is offline. [Authority Sourcing™](https://kyeprotocol.com/authority-sourcing/) ## Use both — the honest recommendation This page argues for a layer, not against a product. If your agents live in the Microsoft stack, their toolkit is a reasonable way to build governance in. KYE Protocol™ is what you add on top so the _authority decision_ and the _evidence_ are vendor-neutral and provable. **The honest boundary.** KYE Protocol™ is not a Microsoft-stack replacement and we will not pretend it is. Keep building agents however you build them. What KYE™ adds is the part a regulator actually tests: a purpose-scoped admissibility decision at the moment of the action, and a [Replay-Proof™](https://kyeprotocol.com/evidence-pack/) record that survives a vendor switch, a framework change, or a courtroom — because it verifies from a published key with no KYE™ service in the loop. That is also why KYE™ can be delivered as **[governance-as-a-service](https://kyeprotocol.com/ai-governance-as-a-service/)** over agents you already run: the service is the authority and the proof, never the agent runtime. ## AI governance, agent governance, and governance as a service — what they mean Buyers search for these terms interchangeably, but they are distinct layers. Here is the plain-language version, and where KYE Protocol™ fits as a service over the agents you already run. ### What is AI governance? AI governance is the practice of proving an AI system acted within policy, law and mandate — purpose, permission, evidence and accountability mapped to frameworks like the EU AI Act™, NIST AI RMF and ISO/IEC 42001™. KYE Protocol™ makes it verifiable rather than asserted. ### What is agent governance? Agent governance applies that discipline to autonomous AI agents that take actions on your behalf — deciding, at the moment of each action, whether the agent is authorised, and sealing the proof. KYE™ treats each agent as a first-class principal with its own authority bindings. ### What is AI governance as a service? AI governance as a service delivers that capability as a managed layer instead of a build-it-yourself toolkit: KYE Protocol™ provides the authority decision and a Replay-Proof™ Evidence Pack™ as a service, mapped across frameworks, with no AI runtime to operate. 249 ### What is agent governance as a service? Agent governance as a service is the same, scoped to agents: KYE™ governs who an agent is allowed to act as and what it may do — across LangChain, CrewAI, the OpenAI and Claude agent SDKs or your own loop — and never runs the agent itself, so governance as a service stays cleanly separate from execution. In short: KYE Protocol™ is vendor-neutral **agent governance as a service** — AI governance and agent governance delivered as a verifiable, Replay-Proof™ service layer over any agent stack, rather than a toolkit you assemble and operate yourself. ## Why each buyer prefers the protocol layer Vendor-neutral authority plus portable proof changes what each role can defend — regardless of which toolkit built the agent. ### For a CISO — when an agent oversteps, you replay the sealed decision and read the exact failed control, instead of reconstructing it from one vendor’s runtime logs. ### For a DPO — you show a supervisory authority exactly what shaped a decision under the EU AI Act™ Article 12 logging duty, in open schemas rather than a vendor’s paraphrase. ### For counsel — a Replay-Proof™ stands on its own signatures; it does not depend on Microsoft, KYE™ or any vendor staying in the loop. Evidence Pack™ ### For a CFO — one neutral authority layer across every agent framework avoids lock-in and cuts duplicated governance spend as agent stacks proliferate.
