# mr_review — gitlab > 23 actions > This page as plain markdown. Index: https://mcp.jmrp.io/llms.txt Canonical: https://mcp.jmrp.io/servers/gitlab/actions/mr_review/ Language: en Alternate: https://mcp.jmrp.io/es/servers/gitlab/actions/mr_review/index.md Updated: 2026-09-11T09:56:41+02:00 License: https://mcp.jmrp.io/license/ Counted with a Free-tier token against gitlab.com, which is the only host this endpoint talks to: to use it against a self-managed instance, run the server yourself — its documentation covers that. The catalog is scoped to the token that asks, so the count moves with both its tier and its permissions: higher tiers expose more actions, and administration domains only appear to tokens allowed to use them. That is why the figures differ elsewhere: the upstream project catalogues 1,006 actions across 162 domains, and 851 on the Free/CE surface, while this deployment publishes 747 because it is OAuth-only and acts with your token, so the administration domains a non-admin account cannot call never appear. All three describe the same catalog, counted from three vantage points. ## Actions ### `mr_review.changes_get` — MR Changes Get _read-only_ Get the current file diffs (changes) for a merge request.
