WHAT IT DOES

What add_checklist does on Trello

AI agents use add_checklist to create or update resources in Trello, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Trello environment.

RISK

Why add_checklist is rated Medium

This is a Write category tool because it creates and modifies data (a checklist) on a Trello card in a reversible manner. The severity is medium because misuse could clutter boards with unwanted checklists, but the action is reversible (checklists can be deleted). Confidence is high because the description clearly indicates a create/modify operation with no side effects beyond the intended checklist creation.

From the tool's definition The tool description states it will 'Create a checklist on a card and optionally seed it with items,' which is a create operation that modifies card state in Trello.

RECOMMENDED RULE

The rule that runs add_checklist safely

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

add_checklist Rate-limited

add_checklist 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.

    "add_checklist": {
      "limits": [
        {
          "counter": "add_checklist_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 Trello, apply this rule, and every add_checklist call is checked against it from then on.
