RISK

Why zendesk_add_comment is rated Medium

Adding comments to tickets creates new data records within Zendesk and modifies the ticket state, making this a Write operation. Severity is medium because comments can affect ticket workflows, customer communication, and support records, but the action is reversible (comments can typically be edited or deleted). The tool does not move money, execute arbitrary code, or permanently destroy data.

From the tool's definition Tool description states 'Add a public or internal comment to a Zendesk ticket' — the verb 'add' and the action of inserting comment data into a ticket system indicates creation/modification of data.

RECOMMENDED RULE

The rule that runs zendesk_add_comment safely

PolicyLayer is an MCP gateway: it sits between your AI agents and UnClick, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For zendesk_add_comment, this is the rule to start with:

zendesk_add_comment Rate-limited

zendesk_add_comment stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

          "counter": "zendesk_add_comment_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect UnClick, apply this rule, and every zendesk_add_comment call is checked against it from then on.
