THE RISK

Why sap_connect needs a policy

The tool name suggests it establishes a connection to an SAP GUI session. Connecting to an SAP system initiates an external session/operation via the SAP GUI Scripting API, which falls under Execute. The description is empty, so confidence is reduced. Given the server context (SAP GUI interaction), misuse could expose sensitive enterprise data or enable further high-impact actions, warranting high severity.

From the tool's definition Tool name 'sap_connect' on a server that 'enables AI assistants to interact with SAP GUI for Windows through the SAP GUI Scripting API'

POLICY

How to control sap_connect

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_connect:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "sap_connect": {
      "limits": [
        {
          "counter": "sap_connect_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

sap_connect stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. 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.
