## Why altegio_list_expense_categories is rated Low

This tool retrieves and enumerates expense categories, which is a read-only query operation with no side effects. It serves to support other operations by providing valid category identifiers, but performs no mutations or external actions itself. The blast radius of misuse is minimal — an agent might retrieve unwanted category information, but cannot modify or delete data.

From the tool's own definition: "Tool name contains 'list' and description states 'List transaction categories' — a pure retrieval operation with no modification, deletion, or execution of external operations. Returns reference data (expense_id values) for use by other tools."

## Use case

AI agents call altegio_list_expense_categories to retrieve information from Allmcp 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 Allmcp:

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