Why sap_set_batch_fields needs a policy

The tool performs batch field modification in SAP GUI, which is a reversible write operation that modifies data. While potentially high-impact due to batch nature and SAP's enterprise criticality, it lacks the irreversibility of Destructive operations or the arbitrary code execution risk of Execute.

From the tool's definition Tool name 'sap_set_batch_fields' indicates setting/modifying multiple fields in batch. The 'set' operation combined with 'batch_fields' implies mass modification of data in SAP. Description is empty, reducing certainty.

POLICY

How to control sap_set_batch_fields

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_set_batch_fields:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "sap_set_batch_fields": {
      "limits": [
        {
          "counter": "sap_set_batch_fields_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

sap_set_batch_fields stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
