# Permissions

> MCP tools follow the same role-based permissions as the Nonce app

## How It Works

MCP uses your Nonce account for authentication. Your role in each workspace determines which tools you can use and what data you can access.

**Your role in the Nonce app = your MCP permissions.**

| Role   | Read (farms, miners, metrics) | Execute (tasks, reboots)  |
| ------ | ----------------------------- | ------------------------- |
| Admin  | Yes                           | Yes                       |
| Member | Yes (assigned farms only)     | Yes (assigned farms only) |
| Viewer | Yes (assigned farms only)     | No                        |

<Note>
  For a complete breakdown of roles and farm scope, see [Role Overview](/user-guide/permissions/role-overview) and [Permission Matrix](/user-guide/permissions/permission-matrix).

## Multi-Workspace Access

If you belong to multiple workspaces, the `ListWorkspaces` tool returns all workspaces you have access to. Each subsequent tool call requires a `workspace_id` parameter to specify which workspace to operate on.
