WHAT IT DOES

What list_bills does on Wpm Mcp Server

AI agents call list_bills to retrieve information from Wpm Mcp Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_bills is rated Low

This is a read-only operation that retrieves bill information. However, bills are inherently financial documents, so even passive access to billing data carries medium severity risk if exposed to an untrusted AI agent (exposure of financial records, payment history, account details).

From the tool's definition Tool name is 'list_bills' and description states it 'Retrieves a list of bills' — a query operation with no modification of data.

list_bills Allowed

list_bills is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
