AI agents call get_client 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.
This tool retrieves client information from the Qonto API without creating, modifying, deleting, or executing any operations. It is a simple read operation that queries existing data. While the Qonto server has financial context, this specific tool only accesses client data, not financial transactions or operations that would require higher severity classification.
From the tool's definition Tool name 'get_client' and description 'Get a specific client from Qonto API' indicate a retrieval operation with no modification or execution capabilities.
Documented attack patterns abuse exactly the kind of access get_client 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_client:
{
"version": "1",
"default": "deny",
"tools": {
"get_client": {}
}
}get_client is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a specific client from Qonto API. 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 get_client: 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.
get_client 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_client 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_client. 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_client 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.
