Lists transactions within a date range.
AI agents call transaction_list to retrieve information from Money Manager 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 transaction data for a specified date range. It performs a read-only operation with no capability to create, modify, delete, or execute external actions. The blast radius of misuse is minimal—an agent could access transaction history, but cannot alter financial state or execute transactions. This is a standard data retrieval operation classified as Read with low severity.
From the tool's definition Tool name 'transaction_list' and description 'Lists transactions within a date range' indicate a query operation that retrieves data without modification or side effects.
Documented attack patterns abuse exactly the kind of access transaction_list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Money Manager MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for transaction_list:
{
"version": "1",
"default": "deny",
"tools": {
"transaction_list": {}
}
}transaction_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Lists transactions within a date range. It is categorised as a Read tool in the Money Manager MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Money Manager MCP Server MCP server in PolicyLayer and add a rule for transaction_list: 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 Money Manager MCP Server. Nothing to install.
transaction_list 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 transaction_list 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 transaction_list. 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.
transaction_list is provided by the Money Manager MCP Server MCP server (shahlaukik/money-manager-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Money Manager MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
