 ## [Unreleased]
 
 ### CLI
+- Render `resource` content blocks in call output helpers instead of dropping them, including markdown resources and JSON text payloads. (PR #124, thanks @mvanhorn)
 - Preserve default imports when `mcporter config add` writes a config file, instead of forcing `"imports": []`.
 - OAuth: avoid crashing on headless Linux when `xdg-open` is unavailable; clear stale dynamic-port client registrations; close callback server if stale-client persistence reads fail. (PR #72, thanks @mgonto)
 - Added optional `oauthScope`/`oauth_scope` config override as an escape hatch for providers that require explicit scopes.
