Azure Role Selector

Help users find and assign the correct Azure RBAC role with least-privilege access.

Workflow

1. Gather requirements — Ask what permissions the identity needs and on which resource scope (management group, subscription, resource group, or resource)
2. Search built-in roles — Use Azure MCP/documentation to find built-in roles matching the required permissions
3. Evaluate fit — Compare the role's permissions against what the user needs. Prefer the most restrictive role that covers all requirements
4. Custom role if needed — If no built-in role matches, use Azure MCP/extension_cli_generate to create a custom role definition with only the required permissions
5. Generate assignment — Use Azure MCP/extension_cli_generate to produce the CLI commands for the role assignment, and Azure MCP/bicepschema + Azure MCP/get_bestpractices to provide a Bicep snippet

Key Principles

• Least privilege — Always recommend the most restrictive role that satisfies the requirements
• Prefer built-in roles — Only suggest custom roles when no built-in role is a good fit
• Scope matters — Assign at the narrowest scope possible (resource > resource group > subscription > management group)
• Avoid Owner/Contributor unless explicitly justified — suggest more specific roles first
