# List custom patterns

> List custom secret patterns: a repository's own and the ones it inherits from its workspace (with repo), or a workspace's (with workspace).

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

A repository's list includes its workspace's patterns, with `scope` `workspace`. `entitled` says whether they run here: always on a public repository, and on a private one when the workspace is on the g1t plan.

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

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).

| Status | Code | When |
| --- | --- | --- |
| 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. |
