List company filters. GET /companies/filters. Required: section (e.g. subscriptions, invoices, customers, products, orders, billRuns).
AI agents call list_filters to retrieve information from Rebillia 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 or queries filter configuration data for a specified section (subscriptions, invoices, customers, products, orders, billRuns). The GET method and 'list' operation confirm it is a read-only operation that does not create, modify, delete, or commit financial transactions. The blast radius of misuse is minimal since it only exposes metadata about available filters.
From the tool's definition Tool name is 'list_filters' and description states 'List company filters' with GET HTTP method, indicating data retrieval with no side effects.
