# Gemini CLI 0.56.0-preview.1: MCP OAuth refresh and false quota-exhaustion fixes

> Preview release. The builder-relevant items are an MCP OAuth token refresh fix (refresh now uses the stored client ID) and a fix for models being falsely reported as capacity-exhausted. The bulk of the changelog is internal "caretaker" issue-triage infrastructure with no user-facing effect.

## What changed


- MCP OAuth tokens now refresh using the stored client ID.
- Fixed false model capacity-exhaustion reports and corrected the core quota-lookup model mapping.
- Capacity exhaustion reclassified as a terminal error.
- Evals: local report command plus developer documentation.
- Remainder is internal caretaker triage/ingestion/eval service work (Firestore schema, Cloud Run jobs, GCP deploy script, prompt tuning) — no user-facing change.
