AI agents call getAccountsAccountIdTransactions to retrieve information from Mcp Upbank without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves transaction data for a specified account without creating, modifying, or deleting any information. It is a straightforward query operation with no side effects. The read-only constraint of the server confirms this classification.
From the tool's definition Tool name 'getAccountsAccountIdTransactions' with prefix 'get' and description 'List transactions by account' indicates retrieval of data with no modification. Server description explicitly states 'read-only mode'.

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