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

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "listar_taxas_iva",
    "arguments": {}

}
```

## Why listar_taxas_iva is rated Low

The prefix 'listar' (list) strongly implies a read/query operation that retrieves VAT rate data without side effects. The description is empty, which reduces confidence, but the naming convention on this server appears consistent (other tools use action verbs like 'adicionar', 'anular', 'atualizar' for write/destructive operations). A listing tool for tax rates is unlikely to cause significant harm if misused.

From the tool's own definition: "Tool name 'listar_taxas_iva' translates from Portuguese to 'list VAT rates' — 'listar' means 'to list' and 'taxas_iva' means 'VAT/tax rates'."

## Use case

AI agents call listar_taxas_iva to retrieve information from MCP Officegest 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 MCP Officegest:

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