# Get someone's permission

> Someone's permission on a repository: their role and its source (owner, base or direct), or null for both when they have none, and the capabilities that role has, from the permission table.

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

Being able to read a public repository does not count as a role. Needs the Write role or higher, or to ask about yourself.

`capabilities` lists what the role allows, in the table's order: `read`, `participate`, `triage`, `push`, `merge`, `run`, `manage_settings`, `manage_protection`, `manage_integrations`, `manage_access`, `administer` and `delete` (which also takes an owner of the workspace). `role` and `source` are null, and `capabilities` empty, for someone with no role. Refused with `403` below the Write role, unless you ask about yourself. See [Access and roles](/guides/access-and-roles/).

- **Authentication:** Required. Send an [access token](/reference/api/#authentication) as `Authorization: Bearer`.
- **MCP tool:** [`access`](/reference/mcp/#access) with `action` `get_permission`, and the same inputs
- **Scope:** An access token needs [`access:read`](/guides/authentication/#scopes).

## Path parameters

| Name | Type | Required | Description |

## Example request

```sh
curl https://api.g1t.sh/repos/flagon-io/hello/collaborators/ada/permission \
  -H "Authorization: Bearer $G1T_TOKEN"
```

## Example response

A successful request answers `200` with:

```json
{
  "username": "ada",
  "role": "triage",
  "source": "direct",
  "capabilities": [
    "read",
    "participate",
    "triage"
  ]
}
```

## 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).

| 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. |
