Why sac_users_patch needs a policy

While reversible (not destructive), it modifies security-sensitive identity data such as user profiles, permissions, or contact information. Unauthorized use could escalate privileges, lock out users, or compromise access controls.

From the tool's definition Tool name 'sac_users_patch' combined with description 'Partial update of a user (SCIM v2 PATCH)' indicates modifying user data. PATCH is a standard HTTP method for partial updates to resources, which creates or modifies data reversibly.

POLICY

How to control sac_users_patch

PolicyLayer is an MCP gateway — it sits between your AI agents and Sap Analytics Cloud, and nothing reaches the server without passing your rules. This is the rule we recommend for sac_users_patch:

policy.json

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

sac_users_patch 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.

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