Module: MCP::Client::OAuth::StorageBackedProvider

Included in:
ClientCredentialsProvider, Provider
Defined in:
lib/mcp/client/oauth/storage_backed_provider.rb

Overview

Shared token/credential persistence for the OAuth provider classes (Provider for the authorization-code flow and ClientCredentialsProvider for the client_credentials flow). The two grants differ in how they authenticate, but both read and write the same two pieces of state through a storage object: the token response and the client information. This module supplies that delegation so the Flow orchestrator can treat any provider uniformly.

Including classes must set @storage to an object responding to tokens, save_tokens(tokens), client_information, and save_client_information(info) (see InMemoryStorage).
