Download a file's content from ERPNext.
AI agents call download_file 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.
The tool itself performs a read-only operation (downloading/retrieving file content), qualifying it as Read category. Severity is medium rather than low because ERPNext systems typically contain sensitive business data (customer information, inventory details, financial records), making unauthorized downloads a meaningful information disclosure risk.
From the tool's definition Tool description states 'Download a file's content from ERPNext' — a retrieval operation with no modification.

Yes. Add a rate_limit block to the download_file 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.
