# Restricted access tokens

A restricted access token lets you provide a token to an automation system or script without exposing all of your capabilities. It cannot grant more rights than you already have.

**Role-based access control (RBAC)** in MK.IO is controlled by granting permissions to users. Each permission is composed of:

* A scope: defines the resources the permission applies to.

* A role: defines what capabilities are granted on those resources.

For more details on RBAC in MK.IO, see [Access, users and teams](/mkio/how-to/managing-your-organization/access-users-and-teams).

## View your RBAC capabilities

Because a restricted access token cannot exceed your existing rights, the first step is to check what you have access to.

Log in to the MK.IO application at [app.mk.io](https://app.mk.io), then open [app.mk.io/api/v1/user/rbac](https://app.mk.io/api/v1/user/rbac) in a second browser tab.

The response is a JSON document that describes your capabilities. If you have access to multiple organizations, switch to the correct organization first to see the right set of capabilities.

The `teams` field shows how your RBAC capabilities are derived. The `rbac` field is what you use when defining a restricted token.

```json
{
  "rbac": {
    "core.customer": {
      "00000000-0000-0000-0000-000000000000": {
        "core.customer": [
          "get",
          "update"
        ],
        "core.invite": [
          "create",
          "delete",
          "get",
          "update"
        ],
        "core.project": [
          "assign",
          "create",
          "delete",
          "get",
          "update"
        ]
      }
    },
    "core.project": {
      "11111111-1111-1111-1111-111111111111": {
        "ams.asset": [
          "create",
          "delete",
          "get",
          "update"
        ],
        "ams.assetfilter": [
          "create",
          "delete",
          "get",
          "update"
        ]
      }
    }
  }
}

```

This example shows capabilities on a single organization (`core.customer`) and a single project (`core.project`).

## Create a restricted token

Send a POST request to the tokens endpoint with a `permissions` object that is a strict subset of the `rbac` object you received above.

```shell
curl --request POST \
     --url https://app.mk.io/api/v1/user/tokens \
     --header 'accept: application/json' \
     --header 'authorization: Bearer bearer-token' \
     --header 'content-type: application/json' \
     --data '
{
  "permissions": {
    "core.project": {
      "11111111-1111-1111-1111-111111111111": {
        "ams.asset": [
          "create",
          "delete",
          "get",
          "update"
        ]
      }
    }
  },
  "type": "restricted",
  "description": "Restricted token for automation",
  "expireDate": "2025-08-22T10:15:00.000Z",
  "organizationId": "00000000-0000-0000-0000-000000000000"
}
'

```

This request creates a token scoped to asset management on project `11111111-1111-1111-1111-111111111111` only. Requests using this token will be denied for any operation outside that scope.

If the request succeeds, the response includes the new token details and the JWT string.

```json
{
  "metadata": {
    "id": "00000000-0000-0000-0000-000000000000",
    "type": "restricted",
    "JWT": "eyJ..."
  },
  "spec": {
    ...
    ...
  }
}

```

Use the returned JWT for subsequent asset management operations.
