Retrieve detailed information about a specific list by ID. Use this when you need comprehensive details about a particular list.
AI agents call get_list to retrieve information from Trello without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a pure read operation on Trello list data. It retrieves and queries information without side effects, aligning with the Read category. Severity is low because accessing list details poses minimal risk—no data is altered, deleted, or executed.
From the tool's definition Tool name and description indicate retrieval: 'Retrieve detailed information about a specific list by ID' with no mention of modification, deletion, or execution of operations.
Documented attack patterns abuse exactly the kind of access get_list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Trello, and nothing reaches the server without passing your rules. This is the rule we recommend for get_list:
{
"version": "1",
"default": "deny",
"tools": {
"get_list": {}
}
}get_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieve detailed information about a specific list by ID. Use this when you need comprehensive details about a particular list. It is categorised as a Read tool in the Trello MCP Server, which means it retrieves data without modifying state.
Register the Trello MCP server in PolicyLayer and add a rule for get_list: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Trello. Nothing to install.
get_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_list rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_list. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_list is provided by the Trello MCP server (v4lheru/trello-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Trello, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
