# list_properties

List properties for a Sanka object family such as orders, companies, or deals. Use this before creating or updating object records when you need the current property schema. Company billing_cycle and payment_cycle are standard company fields, not a custom-property discovery flow.

## Why list_properties is rated Low

This tool retrieves structural metadata about Sanka object families (orders, companies, deals) to discover available properties and fields. It performs a read-only query operation with no capability to modify, delete, or execute external operations. The intended use case is informational—gathering schema information before other operations. No data is modified, deleted, or executed.

From the tool's own definition: "Tool name 'list_properties' and description explicitly states it 'List properties' and is used to query 'the current property schema' before creating or updating records. This is a schema/metadata retrieval operation with no side effects."

## Use case

AI agents call list_properties to retrieve information from Sanka MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Sanka MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_properties": {}
  }
}
```
