Verify recipient account name before making payments.
AI agents call verify_account_name to retrieve information from Mono Banking MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs account name verification, which is a read-only query operation. It retrieves information to validate a recipient account before payment, but does not itself create, modify, delete, execute code, or commit financial transactions. The most severe operation on this server is 'initiate_payment', which is separate.
From the tool's definition Tool name and description indicate 'Verify recipient account name before making payments' — this is a lookup/query operation that retrieves account name information for validation purposes, with no side effects or state changes.

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