FAQPage Schema
What is OAuth 2.0 Protected Resource Metadata in an MCP server?▼

OAuth 2.0 Protected Resource Metadata is a standardized endpoint configuration that allows MCP servers to securely advertise authorization services and scopes, enabling clients to reliably discover trust and scope disclosures.

How do I configure an MCP server to expose OAuth 2.0 Protected Resource Metadata?▼

You configure the MCP server by implementing standardized metadata endpoints over HTTPS and listing trusted authorization servers, aligning the setup with RFC 9728 for proper scope disclosures.

Does my MCP server need to serve OAuth metadata over HTTPS?▼

Yes, your MCP server must serve OAuth 2.0 Protected Resource Metadata over HTTPS to ensure security assurance, maintain client trust, and keep metadata up to date during automated security compliance checks.

How do I audit an MCP server for OAuth 2.0 compliance?▼

You audit an MCP server for OAuth 2.0 compliance by verifying it correctly exposes protected resource metadata according to RFC 9728, checking HTTPS enforcement, and reviewing trusted authorization server listings.

Can I use this approach to validate trusted authorization servers for my MCP server?▼

Yes, you can validate trusted authorization servers by configuring the MCP server with OAuth 2.0 Protected Resource Metadata, which lists trusted authorization servers and specifies the correct scopes for client discovery.

Why does my MCP client fail to discover authorization services?▼

MCP clients fail to discover authorization services when the server lacks properly configured OAuth 2.0 Protected Resource Metadata endpoints, preventing reliable scope and trust disclosures required by RFC 9728.
