Struct SessionToolAuthenticationRequest 

pub struct SessionToolAuthenticationRequest {
    pub id: String,
    pub chat: Uri,
    pub turn_id: String,
    pub tool_call: ToolCallAuthRequiredState,
}

A tool call blocked on MCP authentication mid-execution, surfaced at the session level.

The {@link toolCall} is always a {@link ToolCallAuthRequiredState} (a {@link ToolCallState} in auth-required status). Unlike {@link SessionToolConfirmationRequest}, this is not answered by dispatching a chat/* action directly: the client obtains a token for {@link ToolCallAuthRequiredState.auth | toolCall.auth}.resource and pushes it via the existing authenticate command (see {@link /specification/authentication | Authentication}). The host resumes the tool call and dispatches chat/toolCallAuthResolved once the token is accepted, at which point it also removes this entry with session/inputNeededRemoved.

Fields

id: String

Stable key for this entry, unique within the session’s {@link SessionState.inputNeeded} list. The host derives it however it likes (for example from the chat URI plus the underlying request or tool-call id); consumers MUST treat it as opaque. It is the key for the session/inputNeededSet / session/inputNeededRemoved upsert convention.

chat: Uri

The chat the underlying request lives in. This is the channel a client dispatches its response to — it does not need to have subscribed to that chat first.

turn_id: String

The turn the tool call belongs to.

tool_call: ToolCallAuthRequiredState

The tool call awaiting authentication.
