Get a list of all available DocTypes
AI agents call get_doctypes 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 metadata about available DocTypes in an ERPNext instance. It has no side effects, does not execute code or commands, does not create, modify, or delete data, and does not involve financial operations. It is a simple informational query operation, making it a Read category tool with low severity risk.
