THE RISK

Medium Risk

Why provision_share needs a policy

The tool performs reversible write operations (create share, grant permissions) that alter system state and data access configurations. While high-impact due to the security implications of granting data access, it is not destructive (shares/grants can be revoked), not financial, and not arbitrary code execution.

From the tool's definition Tool description states 'creates Databricks share, grants to recipient' — these are create and modify operations that establish new data sharing relationships and permission grants.

POLICY

How to control provision_share

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

policy.json

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

provision_share 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.
