AI agents call list_qonto_labels to retrieve information from Qonto MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list' prefix strongly suggests data retrieval with no side effects. Within the Qonto financial data context, listing labels is a query operation that retrieves metadata about transaction or account labels. While the server handles sensitive financial information, this particular tool merely reads label definitions, not sensitive transaction or balance data.
From the tool's definition Tool name 'list_qonto_labels' indicates a listing/retrieval operation. Description is empty, but sibling tools on the server (get_client, get_clients, get_qonto_label, etc.) follow a consistent pattern of Read operations for querying financial data without…

PolicyLayer is an MCP gateway — it sits between your AI agents and Qonto MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_qonto_labels:
{
"version": "1",
"default": "deny",
"tools": {
"list_qonto_labels": {}
}
}list_qonto_labels is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_qonto_labels. It is categorised as a Read tool in the Qonto MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Qonto MCP Server MCP server in PolicyLayer and add a rule for list_qonto_labels: 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 Qonto MCP Server. Nothing to install.
list_qonto_labels 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 list_qonto_labels 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 list_qonto_labels. 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.
list_qonto_labels is provided by the Qonto MCP Server MCP server (qonto/qonto-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
