PolicyClient MCP Server

The PolicyClient API, provided by Microsoft as part of the Azure Resource Manager, is a comprehensive interface designed for the governance and enforcement of organizational standards across cloud resources. Its core capability is the lifecycle management of policy assignments, which dictate which policies (rules that evaluate resource compliance) are active and where they are applied within the Azure resource hierarchy. Beyond simple assignment, the API allows users to define customized policies and assign them at various scopes—such as a management group, subscription, resource group, or individual resource—enabling a top-down or targeted approach to control. Typical enterprise use cases include ensuring security configurations (like requiring encryption on storage accounts), enforcing naming conventions, mandating specific resource types for compliance, and automating remediation for non-compliant resources. For consumer or smaller-scale deployments, it provides a straightforward mechanism to apply guardrails that prevent resource sprawl and manage cost by restricting deployments to specific regions or SKUs.
