The Models You Already Pay Azure For
Microsoft Foundry is Azure's platform for deploying and managing models from several vendors in one place, which is how a lot of organizations end up with one model contract instead of five. Where that is the arrangement, AI Intelligence Hub uses those deployments rather than a separate provider relationship, and Foundry's own MCP server is reachable as a tool source. Model governance stays in Azure, under the tenancy and the commercial terms already agreed.
How it connects
Two connections, and they do different jobs. A Foundry-deployed model is reached through its OpenAI-compatible endpoint, configured under the platform's OpenAI provider rather than a Foundry-specific one. The model behind an agent or a node is configuration rather than code, chosen per deployment or per agent, so which Foundry deployment answers a given workflow is a setting. A native Foundry provider, as distinct from the OpenAI-compatible path, is added per engagement.
The second connection is Foundry's MCP server, which Microsoft runs as a hosted endpoint with Entra ID authentication. The platform is an MCP client, and the connection is configured once with a name, the server URL, the transport and the headers carrying its credential. Streamable HTTP, Server-Sent Events and WebSocket are the transports carried. The server's tool list is fetched when the connection binds rather than coded in, so a tool added on the Azure side is usable without reconfiguration.
The connection carries the credential it is configured with, so what it can do in Foundry is bounded by what that credential is granted there. Nothing about model selection is locked: hosted providers and self-hosted servers are both supported, so a deployment can run Foundry models for one agent and something else for another.
What you can do together
- Point an agent at a model already deployed in your Azure tenancy, so inference runs under the contract, region and commercial terms you have rather than a new one.
- Change the model behind a workflow as a configuration setting, without rebuilding the workflow.
- Reach Foundry's own tools through its MCP server, discovered at bind, when a step needs to act on the Azure side.
- Keep some agents on Foundry and others on a self-hosted model, where cost, latency or data-residency reasons differ per use case.
A scenario
- Provider setupAn administrator configures the Foundry deployment as a provider through its OpenAI-compatible endpoint. No model leaves the insurer's Azure tenancy arrangement.
- Agent configurationThe claims assistant in AI Intelligence Hub is set to that deployment. A summarization node in a separate workflow is pointed at a smaller, cheaper deployment.
- ToolingFoundry's MCP server is added with a scoped credential, and its tool list appears in the workflow editor without development.
- In useAn adjuster asks a question and the answer is generated by the Azure-hosted model, with retrieval over the library running under the adjuster's own identity.
- A changeSix months later the insurer moves to a newer model in Foundry. The agent's provider setting is updated and nothing else changes.
What stays where
Model governance stays in Azure
Deployments, regions, quotas and the commercial relationship are managed in Foundry, and the platform consumes what is deployed there.
Content stays in the library
Retrieval runs over the platform's own content under the asking user's identity, and what is sent to the model is what that retrieval returned.
The credential is the boundary on the Foundry side
What the MCP connection can do is what its configured credential is granted, so scoping it is the control.
Processing runs where you deploy the platform
Shared or dedicated SaaS, your own cloud subscription, or your own servers. Reaching a hosted Foundry endpoint needs a network path to it, which an air-gapped deployment does not have; a self-hosted model is the option there.
