Get a single document by DocType and name, including all child tables and linked data
AI agents call get_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 performs a straightforward query operation that retrieves data from the ERPNext system without any side effects. It does not create, modify, delete, execute code, or move money. The use of 'Get' and retrieval language confirms read-only semantics.
From the tool's definition Tool description states 'Get a single document' and retrieves 'all child tables and linked data' — pure retrieval with no modification, deletion, or execution capabilities.
Documented attack patterns abuse exactly the kind of access get_document gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ERPNext MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_document:
{
"version": "1",
"default": "deny",
"tools": {
"get_document": {}
}
}get_document is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a single document by DocType and name, including all child tables and linked data. 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_document: 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_document 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_document 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_document. 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_document is provided by the ERPNext MCP Server MCP server (rakeshgangwar/erpnext-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
