10 `inferenceCredentialHelper` supplies credentials for the inference connection only. An MCP server deployed through [`managedMcpServers`](/docs/third-party/claude-desktop/configuration#managedmcpservers) uses the separate per-server `headersHelper` key, which follows the same execution model but prints a flat JSON header map and has its own cache and renewal settings (`headersHelperTtlSec`, default 300, versus `inferenceCredentialHelperTtlSec`, default 3600). See [Short-lived credentials with a headers helper](/docs/third-party/claude-desktop/extensions#short-lived-credentials-with-a-headers-helper).
