Retrieve detailed information about a specific label by ID. Use this when you need comprehensive details about a particular label.
AI agents call get_label 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.
This tool retrieves label information from Trello. It performs no modifications, deletions, executions, or financial operations. The operation is read-only with minimal blast radius—retrieving label metadata poses negligible security risk.
From the tool's definition Tool name 'get_label' and description 'Retrieve detailed information about a specific label by ID' indicates a query operation that fetches data without modification or side effects.
Documented attack patterns abuse exactly the kind of access get_label 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_label:
{
"version": "1",
"default": "deny",
"tools": {
"get_label": {}
}
}get_label 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 label by ID. Use this when you need comprehensive details about a particular label. 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_label: 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_label 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_label 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_label. 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_label 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.
