Get any document by doctype and name
AI agents call get_generic_document to retrieve information from ERPNext 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 documents from an ERPNext system without creating, modifying, or deleting data. It is a pure Read operation. Severity is medium rather than low because ERPNext systems commonly store sensitive business data (customer details, financial records, inventory), and an AI agent with unconstrained access to get_generic_document could exfiltrate confidential information.
From the tool's definition Tool description states 'Get any document by doctype and name' — a retrieval operation with no modification.
