Why sac_users_update needs a policy

This tool modifies user data irreversibly within the current operation context (though the change itself is reversible via subsequent updates). It affects access control, authentication, and user identity configurations in an enterprise analytics platform. The 'full replace' semantics mean it overwrites existing user state entirely.

From the tool's definition Tool description states 'Full replace of a user (SCIM v2 PUT)' — PUT operations in SCIM perform complete replacement of user records, modifying user attributes, permissions, and configurations.

POLICY

How to control sac_users_update

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_update:

policy.json

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

sac_users_update 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.
