# Read-only mode

> Block mutations while still allowing ephemeral read edits.

Pass `--read-only` to `gps` or `gps-mcp` to refuse user-facing writes.

## Blocked

* Deploy, track promote/rollout/halt
* Listing/image updates
* Review replies
* Monetization create/patch/delete
* Purchase acknowledge/consume/cancel/revoke
* Order refunds
* Explicit `edits.insert` / `edits.commit` / `edits.withEdit`

## Allowed

* Pure GET-style APIs (reviews list, subscriptions list, purchases get, …)
* **Ephemeral edits** for read helpers (tracks list, listings list) — edit is deleted, never committed

## When to use

* Agent sessions that should only inspect production
* CI dry-runs
* Pairing with `--json` for safe automation

```bash theme={"theme":{"light":"github-light","dark":"github-dark"}}
gps-mcp --read-only --credentials ./sa.json
gps --read-only --package com.example.app tracks list
```
