WHAT IT DOES

What add_checklist_items does on Trello MCP Server

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

RISK

Why add_checklist_items is rated Medium

The tool creates or adds checklist items to Trello cards, which is a reversible modification of data. This is a Write operation (create/modify). Severity is medium because while the action is reversible and confined to a single card's checklist, an AI agent could spam cards with unwanted checklist items or clutter project management workflows.

From the tool's definition Tool name 'add_checklist_items' and server context showing 'full CRUD operations' including create actions; sibling tools like 'add_checklist_item', 'add_label_to_card', 'create_card' confirm Write pattern. Description is empty but naming is clear.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_checklist_items safely

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

add_checklist_items Rate-limited

add_checklist_items 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.
