Retrieves transactions from the Qonto API for a specific bank account.

How to control get_qonto_transactions ↓

AI agents call get_qonto_transactions 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.

Low Risk

This tool retrieves historical transaction data without modifying, deleting, or executing financial operations. However, severity is 'high' rather than 'low' because transaction data is sensitive financial information that could expose business operations, client details, and account activity patterns if accessed by a malicious agent.

From the tool's definition Tool name contains 'get_' and description states 'Retrieves transactions', which are read-only operations. No modification, deletion, or financial movement is performed.

Documented attack patterns abuse exactly the kind of access get_qonto_transactions gives an agent:

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 get_qonto_transactions:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_qonto_transactions": {}
  }
}

get_qonto_transactions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Qonto MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
