Options for CloudDevin.loadSession and CloudDevin.attach.

​
Properties

​
McpServer[]
Type: McpServerMCP servers passed to the agent. Tool availability depends on the agent’s support.
​
PermissionHandler
Answer this session’s permission requests. Takes precedence over the client-level onPermission; when neither is set, requests are rejected.
​
"full" | "tail" | "none"
How much history to replay while loading:
  • "full": the whole transcript, as session/load does. The default for loadSession().
  • "tail": only the newest tailLimit events plus a history skeleton (needs the cognition.ai/tailReplay capability; falls back to "full").
  • "none": join the live stream without replaying anything. The default for attach().
​
number
Dense-tail size for replay: "tail"; the server defaults to 300 and caps at 1000.
​
false | SessionTraceOptions
Type: SessionTraceOptionsTrace attributes for this session, merged over the client’s tracing defaults; false leaves the session untraced. No effect without a client-level tracing option.
