AI agents call bills-outstanding to retrieve information from Tally Prime 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 financial data (outstanding bills) from Tally Prime ERP and caches it in an in-memory table. It is a read/query operation with no side effects. Severity is medium because it exposes sensitive financial data including outstanding amounts, party names, and overdue days, which could be misused if accessed by unauthorized parties.
