> List code scanning alerts: problems a tool reported on the default branch, one per tool, category and fingerprint, open first and worst first.

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

In a repository, or (with workspace) across a workspace. Filter by state, severity, tool and rule_id.

`severity` is the rule's security severity when it has one (from its `security-severity` score), else from the result's level: `error` high, `warning` medium, `note` low.

- **Authentication:** Required. Send an [access token](/reference/api/#authentication) as `Authorization: Bearer`.
- **MCP tool:** [`security`](/reference/mcp/#security) with `action` `code_alerts`, and the same inputs
- **Scope:** An access token needs [`security:read`](/guides/authentication/#scopes).
- **Also at:** [`GET /workspaces/{workspace}/code-scanning/alerts`](/reference/api/code-scanning/list-code-scanning-alerts-for-workspace/)

## Errors

A failed request answers with one of these statuses and a body like `{"error": {"code": "not_found", "message": "Repository not found."}}`. See [errors](/reference/api/#errors).

| --- | --- | --- |
| 401 | `unauthenticated` | A token is required, or the one sent is not valid. |
| 403 | `forbidden` | The token is valid but not allowed to do this, such as a member-only change or an agent token outside its repository. |
| 404 | `not_found` | It does not exist, or you cannot see it. |
| 422 | `invalid` | The input is not valid. `message` says which field and why. |
