# snow_create_data_policy

Create a Data Policy (sys_data_policy2) on a table — server-side equivalent of UI Policies, enforced for API/import writes. reverse_if_false re-applies the inverse when the condition turns false. Add field-level rules with snow_create_data_policy_rule.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "snow_create_data_policy",
    "arguments": {}
  }
}
```

## Why snow_create_data_policy is rated Medium

This tool creates new policy records in ServiceNow that enforce constraints on data writes at the API and import level. While reversible (can be deleted), it modifies system behavior and enforces rules that affect all subsequent API operations. This is clearly a Write operation rather than Read (retrieves data) or Destructive (the policy itself is not deleted, just created).

From the tool's own definition: "'Create a Data Policy' — creates a new sys_data_policy2 record on a table. This is a data creation operation that establishes server-side enforcement rules affecting API/import writes."

## Use case

AI agents use snow_create_data_policy to create or update resources in Serac, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Serac environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Serac:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "snow_create_data_policy": {
      "limits": [
        {
          "counter": "snow_create_data_policy_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
