Why rfc_system_info needs a policy

This tool retrieves system information from SAP (likely system name, version, configuration details, etc.) with no side effects. It is a read-only query operation that gathers data for informational purposes. The blast radius of misuse is minimal—exposing system metadata could aid reconnaissance but does not directly compromise data, execute code, or modify systems.

From the tool's definition Tool name 'rfc_system_info' and description 'Get SAP system information using RFC_SYSTEM_INFO' indicate a retrieval operation that fetches system metadata without modifying or executing operations.

POLICY

How to control rfc_system_info

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

policy.json

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

rfc_system_info 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 SAP RFC MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
