  description: >-
    Authentication is declared per operation: API-key, runtime, or connector
    bearer; Automation signature; bootstrap poll token; or anonymous bootstrap
    creation and credential-free pairing redemption. Every general Checkfu REST
    request requires the dated `Checkfu-Version` header (one of: 2026-08-31);
    the three MCP JSON-RPC transports use `MCP-Protocol-Version`, A2A uses
    `A2A-Version`, and the provider OAuth callback carries neither Checkfu
    header. API keys resolve one Workspace without a request selector;
    authenticated responses identify it with `Checkfu-Workspace-Id`.
