## Why canton_list_user_rights is rated Low

The tool retrieves and displays user rights information without side effects. While it accesses permission/authorization data, listing existing rights is a read operation. Severity is low because exposing user rights information poses minimal immediate risk—it aids reconnaissance but does not enable direct privilege escalation or unauthorized actions by itself.

From the tool's own definition: "Tool name contains 'list' (action: retrieval) and description states 'List the rights granted to a Canton user', indicating query/enumeration of existing permissions without modification."

## Use case

AI agents call canton_list_user_rights to retrieve information from Tenzro Ledger MCP 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 Tenzro Ledger MCP:

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