The OAuth 2.0 authorization server that fronts the SiFive Cloud Services (SCS) portal at scs.sifive.com, where SiFive Core Designer and the rest of the SiFive development tooling are delivered. It publishes RFC 8414 authorization server metadata anonymously at /.well-known/oauth-authorization-server, supports the authorization_code and refresh_token grants with PKCE (S256), exposes token, introspection, revocation, userinfo, dynamic client registration and JWKS endpoints, and advertises the openid, mcp:read and mcp:write scopes. The protected resources behind it — including the MCP surface implied by those scopes — require a SiFive customer account.
