Type Alias: AuthServerMetadata
type AuthServerMetadata = OAuthMetadata & {
jwks_uri?: string;
};Authorization server metadata in wire format (snake_case), as fetched from the server's discovery endpoint or provided directly in the configuration.
This is the MCP SDK's RFC 8414 OAuthMetadata type, extended with the jwks_uri field that
mcp-auth requires for JWT verification. The metadata is passed verbatim (no key-casing
transformation) to the SDK's metadata helpers such as oauthMetadataResponse and
mcpAuthMetadataRouter.
Note: mcp-auth validates the fields it consumes (issuer, authorization_endpoint,
token_endpoint, response_types_supported, jwks_uri, grant_types_supported,
code_challenge_methods_supported, registration_endpoint); other fields are passed through
as-is.
