## Why search_supplier_invoices is rated Low

This tool retrieves/queries supplier invoice data based on date filters. It has no capability to modify, delete, or execute actions on invoices. The search operation is a read-only query that returns matching results. While the data being searched (supplier invoices) is financial in nature, the tool itself only performs retrieval and does not move money, commit financial obligations, or have destructive effects.

From the tool's own definition: "'Search incoming (supplier) invoices by date range' - the word 'search' and 'by date range' indicate retrieval and querying of data without modification or deletion."

## Use case

AI agents call search_supplier_invoices to retrieve information from Tripletex 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 Tripletex MCP Server:

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