Best When

A development team building MCP servers needs reference implementations for authentication — particularly when targeting Azure/Microsoft identity platform integration.

Avoid When

You're consuming existing MCP servers (not building them), or need authentication for non-Microsoft identity providers.

Use Cases

• Implementing OAuth 2.0 authentication in custom MCP servers from security-conscious development teams
• Integrating Microsoft Entra ID (Azure AD) with MCP servers from Azure-based development teams
• Learning MCP security patterns from the official Microsoft reference implementation
• Building enterprise-grade authenticated MCP servers from enterprise development teams
• Implementing token-based auth flows for MCP from developer teams following security best practices

Not For

• Direct use as a production MCP server (this is a reference/sample implementation)
• Non-Azure authentication (patterns are Microsoft/Azure-focused)
• Teams not building their own MCP servers — this is for MCP server developers, not users

Authentication

Methods: oauth2

OAuth: Yes Scopes: Yes

Demonstrates OAuth 2.0 and Microsoft Entra ID authentication patterns. Requires Azure AD tenant and app registration for Microsoft identity scenarios. This is a reference implementation, not a client library.

Pricing

Model: free

Free tier: Yes

Requires CC: No

Reference implementation is free. Azure AD has free and paid tiers — basic OAuth2 is free, enterprise features require Azure subscription.

Known Gotchas

⚠ This is a reference/sample implementation — not plug-and-play; requires customization
⚠ Azure AD app registration required for Microsoft identity scenarios
⚠ OAuth2 flows add complexity — agents interacting with auth-protected MCP servers need token management
⚠ Official Azure-Samples quality — well-documented and maintained by Microsoft
⚠ Auth patterns are Microsoft-centric — may need adaptation for non-Microsoft OAuth providers
