Why sap_get_toolbar_buttons needs a policy

This tool performs a read-only query of toolbar button information. It retrieves metadata about available UI controls without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal since the agent can only discover what buttons exist, not interact with them. Consequently, it is classified as Read with low severity.

From the tool's definition Tool name and description indicate it 'List all buttons' on toolbars—a retrieval operation with no side effects. The function queries the state of UI elements (tbar[0] and tbar[1]) without modifying data or executing actions.

How to control sap_get_toolbar_buttons

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP SAP GUI Server, and nothing reaches the server without passing your rules. This is the rule we recommend for sap_get_toolbar_buttons:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "sap_get_toolbar_buttons": {}
  }
}

sap_get_toolbar_buttons is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register MCP SAP GUI Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
