# List milestones

> A repository's milestones: open ones soonest due first (those without a due date after), then closed ones, most recently closed first.

<div class="g1t-endpoint"><span class="g1t-method" data-method="get">GET</span><code>/repos/{owner}/{name}/milestones</code></div>

Each has its number, title, description, due_on (YYYY-MM-DD), state, and open_items and closed_items: its issues and pull requests, a merged pull request counting as closed.

Open milestones soonest due first, then closed ones. Progress is closed_items out of open_items plus closed_items.

- **Authentication:** Optional. Public data can be read without a token; send one to see what is private.
- **MCP tool:** [`repository`](/reference/mcp/#repository) with `action` `list_milestones`, and the same inputs
- **Scope:** An access token needs [`repo:read`](/guides/authentication/#scopes).
