Get field definitions for a DocType.
AI agents call get_doctype_meta 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 field definitions and metadata about DocTypes, which is a read-only operation. It has no side effects on the system state. While metadata disclosure could theoretically aid attackers in reconnaissance, the impact is low compared to other tools on this server that perform CRUD operations.
From the tool's definition Tool name 'get_doctype_meta' and description 'Get field definitions for a DocType' indicate a retrieval operation that queries schema/metadata information without modifying any data.

Get field definitions for a DocType. It is categorised as a Read tool in the ERPNext MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ERPNext MCP Server MCP server in PolicyLayer and add a rule for get_doctype_meta: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches ERPNext MCP Server. Nothing to install.
get_doctype_meta is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_doctype_meta rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_doctype_meta. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_doctype_meta is provided by the ERPNext MCP Server MCP server (yazelin/erpnext-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
