MOST DANGEROUS TOOLS

High Risk

The most dangerous Trello tools

Write · Medium add_checklist This is a Write category tool because it creates and modifies data (a checklist) on a Trello card in a reversible manner. Write · Medium add_checklist_item This is a Write operation because it creates or modifies data reversibly. Write · Low add_comment Adding a comment modifies a card by appending a comment, which is a standard Write operation. Write · Medium add_label Adding a label to a card is a write operation that modifies card state reversibly.

10 of Trello's 16 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Trello

PolicyLayer is an MCP gateway — it sits between your AI agents and Trello, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "add_checklist": {
    "limits": [
      {
        "counter": "add_checklist_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_card": {
    "limits": [
      {
        "counter": "get_card_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Create a free account and register Trello — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
