Constrained GET wrapper for public /api/... Richgo endpoints. This is useful while mapping newly discovered site services.
AI agents call richgo_get_public_api to retrieve information from Richgo Finance MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data from public API endpoints without side effects. The 'constrained GET wrapper' language indicates it is limited to read-only queries. No creation, deletion, execution, or financial transactions are possible. Severity is low because it accesses only public financial data that is already publicly available, posing minimal risk even if misused.
From the tool's definition Tool description states 'Constrained GET wrapper for public /api/... Richgo endpoints' — explicitly a GET operation on public data with no modification or execution capability.
