Generic Frappe get-by-name. Use for any doctype not covered by a dedicated tool.
AI agents call frappe_get_doc to retrieve information from Frappe MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves existing documents by name from the Frappe ERPNext system without modifying, deleting, or executing operations. It is a generic read operation analogous to 'get' or 'fetch' patterns.
From the tool's definition Server description explicitly states 'Read-only MCP server' and tool performs get-by-name retrieval operation which is a query function with no side effects. Tool name 'frappe_get_doc' indicates retrieval of existing documents.
