XSI-AIMS™ for MAF is live on AppSource.
The XSI-AIMS™ for the Microsoft Agent Framework listing is live on Microsoft AppSource. The first substrate runtime of XSI-AIMS™ — the open governance standard XSI published on June 12 — is now one click from any team building on the Microsoft Agent Framework.
May's milestone was approval. This is the listing. A team building on the Microsoft Agent Framework can now add an XSI-AIMS™ governance layer from the same Microsoft commerce surface they already buy through — a Contact-Me listing on Microsoft AppSource, live as of today.
XSI-AIMS™ for the Microsoft Agent Framework is the first substrate runtime of the open standard. It binds the XSI-AIMS governance contract — the Witness Layer that records what an agent did, the Policy Bundle that fences what it was allowed to do, the Bridge-of-Trust Executor that signs who authorized it — into the Microsoft Agent Framework's own enforcement surface, without re-authoring the agents a team has already shipped.
The framework gives you the agent. The spec gives you the contract.
The Microsoft Agent Framework reached general availability this spring with orchestration, tool calling, memory, and observability hooks — everything a team needs to ship an agent. What it does not specify is the governance contract: who authorized an action, under what policy, with evidence a regulator would accept. That gap is what XSI-AIMS closes, and as of today it closes from inside the Microsoft marketplace a MAF team already uses.
"The Microsoft Agent Framework gives a team orchestration, tools, and guardrails. It doesn't tell you who authorized an action, under what policy, with evidence you could hand a regulator — that's the governance contract, and that's what this ships," said Rhyan J Neble, founder of Extended Systems Intelligence. "As of today it installs from the same AppSource surface a MAF team already buys through. It's the first substrate runtime of XSI-AIMS — not the last."
XSI-AIMS tells you what the governance contract is. This is one place you can run it — the Microsoft Agent Framework binding, on AppSource. It isn't the standard itself, and it isn't the only runtime: XSI-AIMS is substrate-agnostic by design, and further bindings build against the same open contract.
