MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Trello MCP Server tools

Destructive · Medium deleteAttachmentFromCard This tool permanently deletes an attachment from a card, which cannot be undone. Destructive · High deleteCard This tool meets the definition of Destructive because it irreversibly deletes data (a Trello card) and cannot be undone. Destructive · Medium deleteCheckItem The tool deletes a checklist item, which is an irreversible operation that cannot be undone through normal means. Destructive · High deleteCheckItemOnChecklist This tool irreversibly removes a check item from a checklist with no undo capability (indicated by 'permanently').

26 of Trello MCP Server's 49 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 MCP Server

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

Deny destructive operations

{
  "deleteAttachmentFromCard": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "addAttachmentToCard": {
    "limits": [
      {
        "counter": "addattachmenttocard_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "downloadFileAttachment": {
    "limits": [
      {
        "counter": "downloadfileattachment_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 MCP Server — 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.
