9898The helper follows the [`inferenceCredentialHelper`](/docs/third-party/claude-desktop/credential-helper) execution model, with three differences: a 30-second time limit, no `CLAUDE_HELPER_CONTEXT`, and no prompting for input. The helper applies only to servers provisioned through managed configuration and never replaces the `Authorization` header on `oauth` entries.

100While the connection is open, only the TTL schedule triggers renewal; a failed request never re-runs the helper. A failed run does not interrupt the connection; Claude Desktop keeps the current headers and retries. A failure while the server is connecting shows the server as needing authentication.
100While the connection is open, the TTL schedule triggers renewal, and a request that the server rejects with HTTP 401 or 403 also re-runs the helper and, when it returns new headers, is retried once with them (Claude Desktop 1.46388.1 or later). A failed helper run does not interrupt the connection; Claude Desktop keeps the current headers and retries on its schedule. A failure while the server is connecting shows the server as needing authentication.

103103 Mid-session renewal requires Claude Desktop 1.21459.0 or later. Earlier versions run the helper only when the server connects.
