List Applications

Returns a slim list of the applications the authenticated caller can access, scoped to their credential: a user sees every application in their active organization, an API key sees the single application it is bound to, and an internal admin sees all applications. Hidden from public docs and intended for MCP clients to select an applicationId without exposing sensitive application settings. MCP clients should call listApplications before application-scoped endpoints. If one application is returned, use it automatically; if multiple applications are returned, ask the user which application to use.
