Update any ERPNext document (partial update). Works on any DocType. Pass doctype (e.g. 'Customer', 'Sales Order'), the document name, and the fields to change. Returns the updated document.
Part of the Mcp Erpnext MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use erpnext_doc_update to create or modify resources in Mcp Erpnext. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call erpnext_doc_update repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Mcp Erpnext.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Update any ERPNext document (partial update). Works on any DocType. Pass doctype (e.g. 'Customer', 'Sales Order'), the document name, and the fields to change. Returns the updated document.. It is categorised as a Write tool in the Mcp Erpnext MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for erpnext_doc_update. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Mcp Erpnext MCP server.
erpnext_doc_update is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the erpnext_doc_update rule in your Intercept 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 Intercept policy for erpnext_doc_update. 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.
erpnext_doc_update is provided by the Mcp Erpnext MCP server (@casys/mcp-erpnext). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
