Google is turning Google Cloud Marketplace into a distribution channel for AI agents, not just software subscriptions. Under the new Agent-as-a-Service framework, third-party developers can list agents directly inside Gemini Enterprise, where enterprise users discover, purchase, and invoke them without leaving Google’s interface. The model centers on Google’s Agent2Agent protocol for interoperability, OAuth 2.0 for delegated authentication, and Dynamic Client Registration to automate credential exchange. Early listed agents include Lovable and Atlassian Rovo, with governance split across Billing Administrator, Discovery Engine Administrator, and end-user roles.
What this means for your business
The organization that decides whether this matters is the one already running Gemini Enterprise or weighing it as a productivity platform. If your workforce is inside Google Workspace and your procurement team is comfortable with Marketplace, you’re now inheriting an agent ecosystem whether you planned for one or not. The governance model Google has designed is explicit about that: a Billing Administrator can subscribe to an agent before the IT organization has reviewed it, putting the Discovery Engine Administrator in a reactive approval role rather than a proactive one.
The A2A protocol is the architectural bet worth scrutinizing. Google is positioning A2A as the neutral interoperability layer for agents the way REST became the default for web services, but it’s a Google-designed standard being enforced inside a Google distribution channel. Vendors who build to A2A compliance gain Marketplace access; vendors who don’t get excluded. That’s not neutrality, it’s a platform tax dressed as a technical standard. The Dynamic Client Registration requirement, which automates the credential handshake between Gemini Enterprise and a third-party agent’s authorization server, genuinely reduces integration friction, but it also tightens Google’s grip on the authentication layer across every agent transaction.
The order-ID-to-security linkage buried in the registration flow is the detail most CIOs will miss and shouldn’t. Before an agent can register with a customer’s environment, the provider must verify that a valid purchase exists by cross-referencing the order ID in the OAuth token against its own billing records. That means procurement and IT provisioning are structurally coupled at the protocol level, not just by policy. If your enterprise has separate budget owners for Marketplace subscriptions and Gemini administration, that coupling will surface as a coordination problem on day one of any agent deployment.
Google’s real move here is collapsing the distance between SaaS discovery and agent invocation into a single interface. If that succeeds, the Marketplace becomes the dominant procurement surface for enterprise AI services, and every vendor who wants enterprise reach has to price and authenticate through Google’s infrastructure. The falsification condition is simple: if Atlassian, Salesforce, or any large ISV builds a parallel agent distribution channel with comparable enterprise reach outside Google’s stack, the A2A standard loses its coercive gravity and becomes just another protocol.
Concept deep-dive: Dynamic Client Registration
Dynamic Client Registration, or DCR, is the process by which a software application registers itself automatically with an authorization server rather than requiring a human administrator to manually exchange credentials. Think of it as a digital handshake that replaces a paper form. In Google’s agent framework, Gemini Enterprise uses DCR to register itself with a third-party agent provider’s systems at the moment of first deployment, verifying purchase legitimacy in the same step. It eliminates a manual provisioning bottleneck that has historically slowed enterprise integrations by days or weeks.
